Survival and Complications of Single Dental Implants in the Edentulous Mandible following Immediate or Delayed Loading: A Randomized Controlled Clinical Trial.

The lifespan of an edentulous mandible with one median implant to hold a full denture for 24 months was evaluated to see if the early loading had any impact on it. Single-implant denture retention for the mandibular region was proposed by "Cordioli et al. in the 1990s. Whether rapid loading and placement of a "single median implant" may result in the implant survival rate comparable to rehabilitation with a single implant and second-stage surgery. It was found that 81 of the 158 implant recipients had quick loading, whereas the rest had delayed loading (77 patients). Patients in the context of "delayed loading group" had follow-up appointments at 1 month, 4 months, 12 months, and 24 months. In addition, the nine implants failed in the 3 months after loading in a quick loading group, while just one implant failed before loading. Median implant survival at 2 years was the study's main goal. Direct loading had a 7% fatality rate advantage over traditional loading because of the alleged advantages of immediate loading, including the avoidance of second-stage surgery. Prosthetic problems were evaluated using Fisher's exact test. A higher rate of implant survival was not seen when implants were loaded more quickly (P = 0.81). A statistically significant difference (P = 0.019) was seen in implant survival between the therapy groups. Single implant loading in an edentulous mandible has a worse survival rate than delayed loading, according to all available research.

Two-Stage Operations in Patients with Acute Right-sided Colonic Obstruction: a 15-year Single Institution Experience

Objective The aim of the study was to review the characteristics, surgical outcomes, complications, and long-term outcomes of two-stage operations for acute right-sided colonic obstruction (RSCO) in a single institution. Summary background data Although patients with acute RSCO can be treated by resection of the tumor with a primary anastomosis, longer procedure times and bigger wounds can result in more mortality and complications. A two-stage operation by diverting loop ileostomy was another surgical option. However, the outcomes of two-stage operations are lacking. Methods The retrospective study reviewed the patients who underwent emergency surgery for acute RSCO in a tertiary center from 2004-2018. First-stage operations other than diverting loop ileostomy, incomplete obstructions that could be treated medically, or pathologies other than adenocarcinomas were excluded. Perioperative data such as first and second operations, operative times, lengths of stay, harvested lymph nodes, and any complications were included. We assessed overall survival (OS) and disease-free survival (DFS) for the oncologic outcomes. Results Sixty-nine patients were included. Seven patients had surgical complications related to ileostomy. Three of them died within 30 days of first admission. Thirty-one patients received a second-stage operation by right hemicolectomy. None had anastomosis leakage or 30-day mortality. Only 9.7% of patients had fewer than 12 harvested lymph nodes. One-year OS was 34% in the patients who received only ileostomy, and 89% in those who received two-stage operations (P < 0.001). Among 26 patients who underwent curative resection of tumor, 3-year DFS was 61.5%. Conclusions A two-stage operation is associated with low mortality and morbidity rates in an emergency setting. The subsequent right hemicolectomy can harvest more lymph nodes than emergency resection. Long-term survival benefits can be expected.

Inflammatory Sinonasal Polyposis-Causing Globe Perforation-With Response to Dupilumab Therapy.

A 75-year-old male patient with asthma presented with left eye vision loss for 1 year and progressive nasal obstruction, anosmia, and purulent eyelid and nasal discharge for several months. There was no light perception vision with an afferent pupillary defect in the left eye. Examination demonstrated nasal dorsum widening, sino-cutaneous fistulae, bilateral proptosis, and left eye chemosis with corneal keratinization in the setting of prior perforation (Fig. 1A). Nasal endoscopy showed severe, bilateral polyposis (Fig. 1B). MRI revealed an extensive sinonasal process with left globe disfigurement and severe, postobstructive, sinus mucocele formation (Fig. 2, top). The patient underwent bilateral functional endoscopic sinus surgery. Intraoperatively extensive sinonasal polyposis and inspissated mucinous debris were encountered. Histopathology demonstrated nasal polyps with dense eosinophilic infiltration and cultures grew polymicrobial bacteria. He underwent left eye evisceration, left lower eyelid ectropion repair, and second-stage sinus surgery. Postoperatively, there were improvements in pain, breathing, and smell. Nasal endoscopy displayed improved sinus patency, although with rapid polyp recurrence. Given concern for mucocele formation and potential impact on the right eye, bimonthly subcutaneous dupilumab was initiated. Following 5 doses, there was dramatic improvement, with symptom resolution, nasal bridge narrowing, sinonasal polyposis reduction, and fistulae closure (Fig. 1C). Subsequent CT showed dramatic polyposis involution and sinus clearing (Fig. 2, bottom). Severe chronic sinusitis with polyposis may exert mass effect on local structures including the brain, optic nerves, and globes. Among patients with severe, refractory, or recurrent polyposis, subcutaneous dupilumab may provide a dramatic clinical response.FIG. 1FIG. 2

Automated prediction of cardiorespiratory deterioration in patients with single-ventricle parallel circulation: A multicenter validation study

ObjectivesPatients with single-ventricle physiology have a significant risk of cardiorespiratory deterioration between their first- and second-stage palliation surgeries. Detection of deterioration episodes may allow for early intervention and improved outcomes. MethodsA prospective study was executed at Nationwide Children's Hospital, Children's Hospital of Philadelphia, and Children's Hospital Colorado to collect physiologic data of subjects with single ventricle physiology during all hospitalizations between neonatal palliation and II surgeries using the Sickbay software platform (Medical Informatics Corp). Timing of cardiorespiratory deterioration events was captured via chart review. The predictive algorithm previously developed and validated at Texas Children's Hospital was applied to these data without retraining. Standard metrics such as receiver operating curve area, positive and negative likelihood ratio, and alert rates were calculated to establish clinical performance of the predictive algorithm. ResultsOur cohort consisted of 58 subjects admitted to the cardiac intensive care unit and stepdown units of participating centers over 14 months. Approximately 28,991 hours of high-resolution physiologic waveform and vital sign data were collected using the Sickbay. A total of 30 cardiorespiratory deterioration events were observed. the risk index metric generated by our algorithm was found to be both sensitive and specific for detecting impending events one to two hours in advance of overt extremis (receiver operating curve = 0.927). ConclusionsOur algorithm can provide a 1- to 2-hour advanced warning for 53.6% of all cardiorespiratory deterioration events in children with single ventricle physiology during their initial postop course as well as interstage hospitalizations after stage I palliation with only 2.5 alarms being generated per patient per day.

Caracterización de la reinfección de prótesis articular tras recambio en 2 tiempos (infección de la prótesis del 2.o tiempo). Un estudio multicéntrico

IntroductionTwo-stage exchange is the gold standard in the surgical management of prosthetic joint infection (PJI). However, perioperative reinfections (RePJI) can occur to newly inserted prosthesis, which highlights the importance of an adequate antibiotic prophylaxis, although there is scarce evidence in this field. Our objective was to evaluate the characteristics of RePJI, its prognosis and the antibiotic prophylaxis that is commonly used in second-stage surgery. MethodsMulticentric retrospective observational study in Spanish hospitals including patients with RePJI between 2009 and 2018. ResultsWe included 92 patients with RePJI from 12 hospitals. The most frequent isolated microorganism was Staphylococcus epidermidis in 35 cases (38.5%); 61.1% of staphylococci were methiciliin-resistant. In 12 cases (13%), the same microorganism causing the primary PJI was isolated in RePJI. When comparing with the microbiology of primary PJI, there were more cases caused by Gram-negative bacteria (the most frequent was Pseudomonas spp.) and less by Gram-positive bacteria. Failure occurred in 69 cases (75%). There were 43 different courses of antibiotic prophylaxis after the second-stage surgery; the most frequent was a unique preoperative cefazolin dose, but most patients received prophylaxis before and after the second-stage surgery (61 cases). ConclusionsThe most frequent microorganisms in RePJI are coagulase-negative staphylococci, although Gram-negative bacteria, especially Pseudomonas spp. are also common. There is a significant heterogeneity in antibiotic prophylaxis for a second-stage surgery. ReIPJI treatment has a high failure rate.

Efficacité de la fixation interne précoce associée à un lambeau libre pour le traitement des fractures ouvertes de l’avant-bras Gustilo IIIB

IntroductionGustilo IIIB open forearm fractures are severe injuries often associated with extensive bone and soft tissue injuries. The treatment of Gustilo IIIB open forearm fractures remains a challenging problem, with a high morbidity rate such as infection, nonunion, even amputation. External fixation is preferred for open lower limb fractures. However, there are significant differences between open bone injuries of the upper and lower extremity in terms of treatment plans. Use of internal fixation methods for open fractures is a controversial issue, as it requires early coverage of skin and soft tissue defects after radical debridement and irrigation. The optimal approach for open forearm fractures remains to be determined. The present study evaluated whether early internal fixation combined with free flap placement is effective for the treatment of Gustilo IIIB open forearm fracture. HypothesisEarly internal fixation combined with the free flap technique in the treatment of Gustilo IIIB open forearm fracture provides good consolidation results. Material and methodsFrom January 2015 to January 2020, 20 patients with Gustilo IIIB open forearm fracture treated with early internal fixation combined with free skin flap placement were retrospectively analyzed. There were 9 males and 11 females, with an average age of 40years. In all cases, the injuries were classified as Gustilo type IIIB. The area of the wounds ranged from 9×3cm to 27×10cm. Fist-stage plate fixation was adopted in 16 cases. Four patients presenting with major contamination received first-stage fixation with Kirschner wires and external fixation, and the second-stage surgery of surgical treatment included flap placement and internal fixation within 10days. The rates of limb salvage and complications were recorded. The Anderson scoring system was utilized to assess limb function. ResultsLimb salvage was successful in all 20 cases. The average length of hospital was 19 days (range, 7–28days). Four patients developed superficial infections. After debridement, the wounds were covered with skin grafts. No deep infections or osteomyelitis occurred. Three patients developed nonunion, and bone grafts achieved bone healing later. The donor skin flaps healed well, with partial pigmentation. No complete necrosis of the flaps occurred. Only the distal part of flaps became necrotic in two cases, which were then successfully treated by debridement and skin grafting. The average follow-up duration was 14.7months (range, 8–24months). According to the Anderson scoring system, 7 cases were graded as excellent, 6 cases as good, 5 cases as fair, and 2 cases as poor. ConclusionFor Gustilo IIIB type injuries, early and thorough debridement along with early internal fixation and skin flap coverage of the wound can achieve satisfactory clinical results, shorten the treatment cycle, and maximize limb function recovery. Level of evidenceIV; retrospective study without control group.

Comparison of functional and esthetic outcomes in digital versus analog rehabilitation of one-piece screw-retained implant crowns placed at second stage surgery.

Analog and digital impressions are established procedures for restoration of single-tooth implants. In this study, single-tooth implants were restored with definitive restorations during second-stage surgery. Analog and digital workflows were compared. Eighty single-tooth implants were examined in total. In 40 implants, an index was taken immediately after implant placement using composite resin to fabricate the final crowns (analog workflow). For the other 40 single-tooth implants, intraoral intraoperative scans were performed (digital workflow) during primary surgery. The custom-fabricated screw-retained crowns were placed during second-stage surgery. Photographs and examinations for the scores were taken at the time of the follow-up visit, 1-4 years after placement of the crowns. The number of treatment appointments required was recorded and the modified pink esthetic score (PES) was determined. Additionally, the functional implant prosthetic score (FIPS) was measured. The mean PES was 12.15/14 for the digital workflow and 11.95/14 for the analog workflow. The most common deficit was incomplete papillae for both workflows. Three treatment appointments were required for both workflows: (1) Scan and/or impressions making and patient consent, (2) implant placement, and (3) second-stage surgery with crown insertion. The FIPS was 9.1/10 for the digital workflow group and 9.2 /10 for the analog workflow group. Common deficits presented as missing papillae as well as open approximal contacts. The FIPS was not significantly different between workflows (p = 0.679). The PES also did not show a statistically significant difference for both workflows (p = 0.654), however the analog workflow showed better values for the papillae (p < 0.05). A significant difference was also found in the other PES values, with the digital workflow showing better results here (p < 0.05). A chronological analysis of the results of the digital technique showed that the cases treated last had significantly better values than the cases treated first. According to the results of this study, both workflows allowed placement of the definitive crowns on single-tooth implants during second-stage surgery. Both workflows were found to be equivalent in terms of esthetic results in this study, although the digital workflow demonstrated a learning curve. This article is protected by copyright.

(280) Second Stage Surgery After Ring Flap Metoidioplasty: Technique and Outcomes

Abstract Introduction Metoidioplasty is an option for creation of external male-appearing genitalia in transmasculine individuals. Many individuals report good sensory, functional, and aesthetic outcomes following single-stage metoidioplasty with urethral lengthening and scrotoplasty. However, an average of 12% of patients require a second-stage surgery to improve aesthetic appearance, place testicular implants, address complications, and maximally lengthen the neophallus. These procedures are risky to perform at the time of initial metoidioplasty as this may disrupt the vascular supply to the neoscrotum via the anterior branches of the external pudendal artery. We report outcomes of second-stage ring-flap labial metoidioplasty involving monsplasty, upper labia majora dermatolipectomy, and scrotoplasty with testicular implant insertion. Objective Transmasculine individuals who have had metoidioplasty with rotational advancement labia majora flap and (Ghent style) scrotoplasty often desire monsplasty, upper labia majora tissue resection, and testis implant insertion to optimize aesthetics, reduce dysphoria and improve voiding function. We describe our technique and surgical outcomes with dermatolipectomy of the mons pubis (monsplasty) and upper labia majora with simultaneous testis implant insertion. Methods We retrospectively reviewed the outcomes of ring flap metoidioplasty patients who underwent second stage surgery involving monsplasty and upper labia majora dermatolipectomy, and testis implant insertion. Monsplasty is performed by excising excess skin and adipose tissue to better expose the penis and lift the genitals. Upper labia majora tissue is subsequently resected, followed by development of pockets into each hemiscrotum inferiorly. Silicone carving implants are then individually sized and inserted to serve as testicular prostheses. Results From November 2017 to January 2022, 13 patients underwent second stage metoidioplasty and scrotoplasty with testis implant insertion. Mean follow-up was 22 months. Monsplasty was not desired/necessary in two (15%) patients. Implant malposition occurred in one (7.7%) patient, and one (7.7%) patient was unhappy with the overall aesthetics prompting him to seek a second opinion. To date, no surgical revision was desired nor performed. There were no wound or implant infections, and no scrotal necrosis. Conclusions Monsplasty and upper labia majora dermatolipectomy with simultaneous testis implant insertion is a safe and reliable combination of surgeries after metoidioplasty with Ghent style scrotoplasty.

Modified Reconstruction Technique to Adapt Management of Severe Group IIB Tanzer Constricted Ear Deformity.

A prospective study includes 20 patients who underwent modified autologous reconstruction using costal cartilage for unilateral severe grade IIB constricted ears in the period between October 2018 and November 2021. Mean follow-up period was 6 months. Satisfaction was recorded using a questionnaire form 4 months after second-stage surgery. Patients reported excellent (n = 14) and good (n = 7) results. According to a four-point Likert scale, the average aesthetic outcome score was 3.8. No complications were recorded, except in one patient who shows postoperative collection. The helix, concha, and lobule were the most satisfying parts to patients. The least pleasing subunit to patients was the antihelix. All patients were satisfied with the elevation of the auricle. They reported symmetry in size, shape, and position in 14 of 20 (70%) patients. Modified autogenous auricular reconstruction is useful in correcting severe group IIB Tanzer constricted ear deformities. Because it addresses all the anatomical features of this deformity, this technique is reproducible and reliable and has offered consistently effective results.

Systemic antibiotics are not required for successful two-stage revision hip arthroplasty.

The duration of systemic antibiotic treatment following first-stage revision surgery for periprosthetic joint infection (PJI) after total hip arthroplasty (THA) is contentious. Our philosophy is to perform an aggressive debridement, and to use a high local concentration of targeted antibiotics in cement beads and systemic prophylactic antibiotics alone. The aim of this study was to assess the success of this philosophy in the management of PJI of the hip using our two-stage protocol. The study involved a retrospective review of our prospectively collected database from which we identified all patients who underwent an intended two-stage revision for PJI of the hip. All patients had a diagnosis of PJI according to the major criteria of the Musculoskeletal Infection Society (MSIS) 2013, a minimum five-year follow-up, and were assessed using the MSIS working group outcome-reporting tool. The outcomes were grouped into 'successful' or 'unsuccessful'. A total of 299 two-stage revision THAs in 289 patients met the inclusion criteria, of whom 258 (86%) proceeded to second-stage surgery. Their mean age was 68.1 years (28 to 92). The median follow-up was 10.7 years (interquartile range (IQR) 6.3 to 15.0). A 91% success rate was seen in those patients who underwent reimplantation, decreasing to 86% when including those who did not proceed to reimplantation. The median duration of postoperative systemic antibiotics following the first stage was five days (IQR 5 to 9). There was no significant difference in outcome between those patients who were treated with antibiotics for ≤ 48 hours (p = 0.961) or ≤ five days (p = 0.376) compared with those who were treated with longer courses. Greater success rates were seen for Gram-positive PJIs (87%) than for Gram-negative (84%) and mixed-Gram PJIs (72%; p = 0.098). Aggressive surgical debridement with a high local concentration of targeted antibiotics at the time of first-stage revision surgery for PJI of the hip, without prolonged systemic antibiotics, provides a high rate of success, responsible antibiotic stewardship, and reduced hospital costs.

Firm elevation of the auricle in reconstruction of microtia with a retroauricular fascial flap wrapping two titanium plate struts

BackgroundReconstruction of the cephaloauricular sulcus in patients with microtia in ear reconstructions remains challenging. Costal cartilage and other support materials wedge were used for ear elevation. Each material has its disadvantages. To reconstruct a stable cephaloauricular sulcus and reduce costal cartilage harvesting, we used two titanium plate struts to support the costal cartilage framework. MethodsA titanium plate strut was designed. The angle of the strut was 60°, the arm length was 0.8 cm, and the width was 0.5 cm. The thickness was 0.6 mm. Four small pores are formed on the titanium plate. The implanted framework was separated from the underlying bed. Two titanium plate struts were fixed on the raised ear framework, tendon, and periosteum, and then wrapped with a turned-over retroauricular fascia flap. The raw surface was covered with a split-thickness skin graft, harvested from the scalp. ResultsFrom 2019 to 2022, 51 patients underwent second-stage operations. All patients were followed up for a minimum of 6 months. The auricular projection was well-maintained, and the cephaloauricular sulcus of the constructed auricle was acceptable in 50 patients. There was one infection, and the titanium plate struts were removed, which resulted in shrinking cephaloauricular angles. ConclusionsTitanium plate is effective as a supportive material to obtain the proper and firm projection of the constructed auricle. It provides a new option for patients whose costal cartilage volume is insufficient or who do not want to have the costal cartilage harvested again.

Surgical Treatment of Facial Abscesses and Jaw Osteomyelitis of Dental Origin Using Extraoral Tooth Extraction in the Domestic Rabbit: A Case Series.

The treatment of facial abscesses of dental origin is difficult as jaw osteomyelitis in rabbits is mainly associated with a thick caseous pus that is particularly difficult to drain. Precise identification of the teeth involved in the infected site with the use of cone beam computed tomography (CBCT) was expected to ensure a favorable surgical treatment plan without a long-term local antibiotic strategy or local marsupialization. The first part of the study compared multi-planar reconstruction (MPR) and 3D reconstruction complemented by a maximum intensity projection filter (MIP). The surgical part of the study included rabbits with documentation of the treatment outcome for a period greater than one month after surgery and having had at least one post-operative CBCT demonstrating the achievement of surgical extraction. MPR is significantly more efficient than MIP techniques for alveolar bone (P < 10-7), spongious bone (P < 10-10) and apical elongation (P < 10-5) parameters. Nineteen of 20 surgical sites gave radiological confirmation of the success of the surgical plan. Eighteen of 20 of the abscess sites were clinically healed within one month. Seven out of 20 of the abscess sites presented evidence of one dental structure regrowth following the CBCT recheck. Two out of these seven cases presented with a concomitant persistent chronic facial fistula. Both cases healed after second-stage surgery to extract the tooth structure. The mean number of teeth extracted was 2.85, and seven of the 20 procedures included one incisor.

Autologous myocutaneous flap implantation for chronic refractory chest wall sinus with infection: a case report

BackgroundChest wall sinus with infection is a refractory disease caused by a variety of susceptible factors, and the treatment is still challenging. For clinically complex cases, although there are various surgical methods to choose from, it is still very difficult to achieve clinical cure, especially for patients with older age and many underlying diseases. Complete resection of chest wall sinus and application of repair and reconstruction technology may bring hope to refractory cases.Case presentationHerein, we report a case of a 67 year-old woman who had undergone breast cancer surgery and a history of multiple cycles of radiotherapy and chemotherapy. One year ago, she had a fistula in the left chest wall with yellow purulent fluid. After admission to our hospital, chest computed tomography (CT) showed the formation of the left chest wall sinus, accompanied by high-density images of the left clavicle, part of the ribs and part of the sternu. According to the patient's symptoms, signs and imaging examination, we preliminarily diagnosed the patient as chest wall sinus with infection and chronic osteomyelitis. Therefore, in the first-stage operation, the patient underwent left chest wall sinus resection, left partial rib resection, left partial clavicular resection and left partial sternal resection, After surgery, the wound surface was changed with gauze dressing with sensitive antibiotic solution every day until the wound surface was clean and new granulation was formed. In the second-stage operation, the wound surface was appropriately expanded, and the pedicled latissimus dorsi myocutaneous flap was transferred to the chest wall defect. Finally, the skin paddle was sutured without tension to the normal skin around the chest, and two drainage tubes were placed. Anti-infection, anti-spasm, anti-coagulation and other treatments were given after operation, and the survival of myocutaneous flap, wound healing and sinus disappearance were observed.ConclusionThe application of pedicled latissimus dorsi myocutaneous flap in the treatment of intractable chronic chest wall sinus is an effective method. It does not change the shape of the thorax. The clinical effect is satisfactory in the near and medium term, which is worthy of clinical promotion.

Microureteroscopy in the treatment of upper urinary tract stones in pediatric patients younger than 3years of age.

The aim of this study is to evaluate the usefulness of microureteroscopy (m-URS) in the treatment of renal and ureteral stones in children younger than 3years of age. A retrospective analysis of pediatric patients aged < 3years with upper urinary tract calculi who underwent lithotripsy was performed. The children were divided into the m-URS group (4.85 F, n = 41) and the ureteroscopy (URS) group (4.5/6.5 F, n = 42) according to the type of ureteroscope used. The mean age of the patients was 23.5 ± 10.7months in the m-URS group and 20.6 ± 7.1months in the URS group (P = 0.212). The success rate of one-stage surgery was 80.5% (33/41) for m-URS and 38.1% (16/42) for URS (P < 0.001). The success rates of m-URS were 60.0%, 69.2%, and 91.3% for stones located in the renal pelvis/calix, upper ureter, and mid-lower ureter, respectively. Eight children in the m-URS group and 26 children in the URS group underwent the second-stage ureteroscopic surgery. The mean operation time was 50 (30-60) min in the m-URS group and 40 (34-60) min in the URS group (P = 0.287). The complication rates were 4.9% and 7.1% in the m-URS and URS groups, respectively (P = 1.000). The stone-free rate at 1 month after lithotripsy was 87.8% in the m-URS group and 83.3% in the URS group (P = 0.563). The mean anesthesia session was 2.1 in the m-URS group and 2.5 in the URS group (P = 0.002). M-URS can effectively reduce the number of anesthesia sessions and is considered an alternative treatment for upper urinary tract calculi in selected pediatric patients younger than 3years of age.

Rehabilitation of a completely edentulous patient with fixed implant prosthesis on titanium framework

Rationale: This article describes step by step procedure for the rehabilitation of a completely edentulous patient with 12 endosseous implants followed by the fabrication of the Malo bridge with CAD-CAM fabricated titanium framework. Patient Concerns: The patient with a chief complaint of ill-fitting conventional complete denture reported to the hospital and wanted a fixed rehabilitation. Diagnosis: The patient was diagnosed with completely edentulous maxillary and mandibular arches without any systemic illness. Interventions: Twelve implants (Neobio tech) were placed in maxillary and mandibular arches (6 in each arch). After osseointegration, healing abutments were placed during the second stage of surgery. A final impression was made using the open tray technique. The accuracy of the impression was verified using jig trial and OPG. This was followed by jaw relation and try-in. A titanium metallic framework was positioned on the implants to check the fit. A Malo bridge with individual cementable zirconium crowns was fabricated. The metallic framework was torqued to 35N and crowns were cemented using Implant Premier cement. The screw holes were packed with Teflon tape and restored using composite. Outcomes: The patient was satisfied with the treatment outcome. Follow up were done after 10 years with no significant complications. Lessons: Fixed implant prosthesis with titanium framework was found to be a successful treatment protocol for the rehabilitation of the completely edentulous patient.

Effect of preoperative estrogen on complications after proximal hypospadias repair: A randomized controlled trial.

Proximal hypospadias repair has many postoperative complications such as urethrocutaneous fistulae, wound dehiscence, and urethral stricture. The beneficial effect of estrogen to promote wound healing has been known. We designed a study to determine whether preoperative stimulation of tissue with estrogen can reduce the postoperative complications associated with wound healing in patients undergoing hypospadias repair. Patients with proximal hypospadias requiring two-stage repairs (chordee correction followed by urethral tubularization) were randomized to estrogen and control groups before the second stage of surgery. In the former, topical estrogen cream (0.5 mg of estriol) was applied to the ventral penis for a month, whereas normal saline gel was applied to the latter; the urethroplasty was carried out thereafter. Patients were followed up for complications. There were 29 patients in the estrogen group and 31 in the placebo group after the exclusion criteria were met. There was no significant difference in the overall postoperative complications between the estrogen group (44.8%) and the placebo group (51.6%). The occurrence of urethrocutaneous fistula (37.9% vs. 51.6%) and dehiscence (41.4% vs. 45.2%) was not significantly different between the estrogen and placebo groups. Neourethral stricture occurred in four patients in the estrogen group, while none of the patients in the placebo group developed stricture. The preoperative application of topical estrogen cream to the ventral penis failed to demonstrate any significant effect on wound healing and complications.

Primary Ear Reconstruction Using Cadaveric Costal Cartilage.

Allogeneic cadaveric costal cartilage is commonly used for grafts in nasal reconstruction surgery; however, limited information exists on its use in total ear reconstruction for microtia. In this case series, we describe the novel use of cadaveric cartilage for auricular framework construction in ear reconstruction and review preliminary histologic findings. Patients requiring primary complete reconstruction of the auricle from August 2020 to December 2021 were eligible and underwent ear reconstruction using cadaveric costal cartilage. Patients were evaluated for surgical site infection, skin necrosis, cartilage resorption, and cartilage exposure during regular follow-up visits. Two cartilage samples were taken after 2 separate second-stage surgeries done 52 weeks after first-stage reconstruction. These samples were stained with hematoxylin and eosin as well as safranin-O and examined under light microscopy. A total of 12 ear reconstruction procedures using cadaveric costal cartilage were performed across 11 patients; 10 of 12 ears had type III microtia and 2 of 12 ears had type IV microtia. Patients ranged from 4 to 25 years old at the time of surgery, with an average age of 10.7 years. Follow-up time ranged from 1.6 to 25.4 months, with a mean follow-up time of 11.2 months. No patients experienced any visibly significant cartilage warping. Two patients experienced minor construct exposure, which were successfully salvaged. Two patients experienced surgical site infections, one lead to resorption requiring framework replacement. Preliminary histologic analysis of the 2 samples taken 1 year after implantation showed viable chondrocytes with no evidence of immunologic rejection or any local inflammation or host foreign body response. Cadaveric costal cartilage serves as a viable alternative to autologous cartilage and other alloplastic biomaterials for construction of auricular frameworks in primary microtia reconstruction. Resorption secondary to infection and construct exposure remain potential risks. Longer follow-up times and a larger sample size are needed for assessment of long-term efficacy.

Staged Resection of Difficult-to-Treat Intracranial Meningiomas: A Systematic Review of the Indications, Surgical Approaches, and Postoperative Outcomes.

Introduction Meningiomas-the most common extra-axial tumors-are benign, slow-growing dural-based lesions that can involve multiple cranial fossae and can progress insidiously for years until coming to clinical attention secondary to compression of adjacent neurovascular structures. For complex, multicompartmental lesions, multistaged surgeries have been increasingly shown to enhance maximal safe resection while minimizing adverse sequela. Here, we systematically review the extant literature to highlight the merits of staged resection. Methods PubMed, Scopus, and Web of Science databases were queried to identify articles reporting resections of intracranial meningiomas using a multistaged approach, and articles were screened for possible inclusion in a systematic process performed by two authors. Results Of 118 identified studies, 36 describing 169 patients (mean age 42.6 ± 21.3 years) met inclusion/exclusion criteria. Petroclival lesions comprised 57% of cases, with the most common indications for a multistaged approach being large size, close approximation of critical neurovascular structures, minimization of brain retraction, identification and ligation of deep vessels feeding the tumor, and resection of residual tumor found on postoperative imaging. Most second-stage surgeries occurred within 3 months of the index surgery. Few complications were reported and multistaged resections appeared to be well tolerated overall. Conclusions Current literature suggests multistaged approaches for meningioma resection are well-tolerated. However, there is insufficient comparative evidence to draw definitive conclusions about its advantages over an unstaged approach. There are similarly insufficient data to generate an evidence-based decision-making framework for when a staged approach should be employed. This highlights the need for collaborative efforts among skull base surgeons to establish an evidentiary to support the use of staged approaches and to outline those indications that merit such an approach.

Outcomes of surgical treatment of congenital cataract with microphthalmia in infancy

Objective: To examine the outcomes of surgical treatment for infants with congenital cataract and microphthalmia (CATM). Methods: It was a retrospective case series study. Data of 28 (55 eyes) CATM children who underwent cataract surgery at the Qingdao Eye Hospital of Shandong First Medical University and were followed up for more than 5 years between January 2010 and December 2014 under the age of 6 months. There were 15 male and 13 female children. The age at the time of surgery was (3.2±1.3) months, and the follow-up time was (8.2±1.7) years. The data included the basic information of the children, the ocular biological parameters before and after surgery and intraocular lens (IOL) implantation, and the occurrence of complications. Paired t-tests or Wilcoxon signed rank tests were used to compare groups, and logistic regression analysis was used to identify factors related to IOL implantation, secondary glaucoma, and visual axis opacification (VAO). Results: The mean preoperative axial length was (16.6±1.0) mm, and the mean horizontal corneal diameter was (9.5±0.9) mm. The axial growth rate within 2 years after the first stage of surgery was (1.4±0.8) mm/year. None of the children had an IOL implanted before the age of 2. Sixty percent of the eyes (33/55) received IOL implantation within 2 to 4 years after the first stage of surgery, while the remaining 40% (22/55) did not receive IOL implantation at the last follow-up. The axial growth rate was (0.9±0.7) mm/year within two years after the second stage of surgery. Postoperative secondary glaucoma occurred in 7 eyes (12.7%), and VAO occurred in 15 eyes (27.3%). IOL implantation was associated with preoperative axial length (OR=0.072, P<0.001) and age at the first stage of surgery (OR=7.270, P<0.001), but not with preoperative corneal diameter (P=0.735). The incidence of VAO was associated with preoperative corneal diameter (OR=4.124, P=0.011), but not with age at the first stage of surgery (P=0.489) or preoperative axial length (P=0.489). No factors related to the occurrence of secondary glaucoma were found. The best corrected visual acuity at the last follow-up after IOL implantation was (0.37±0.28) logMAR, which was better than that of children without IOL implantation (0.67±0.19) logMAR (U=49.50, P=0.003). Conclusions: Children with CATM can obtain the opportunity for IOL implantation through early surgery and ultimately achieve good visual outcomes. Properly selecting the timing for implanting IOL can keep the incidence of secondary glaucoma at an acceptable level.

A Permanent Articulating Spacer Versus Two-Stage Exchange for Chronic Periprosthetic Joint Infection: A Propensity Score-Matched Study

BackgroundAlthough 2-stage revision has been proposed as gold standard for periprosthetic joint infection treatment, limited evidence exists for the role of articulating spacers as definitive management. The purpose of this study was to compare clinical outcomes and costs associated with articulating spacers (1.5-stage) and a matched 2-stage cohort. MethodsA retrospective review was performed for patients who had chronic periprosthetic joint infections after total knee arthroplasty defined by Musculoskeletal Infection Society criteria and were matched via propensity score matching using cumulative Musculoskeletal Infection Society scores and a comorbidity index. Patients who maintained an articulating spacer (cemented cobalt-chrome femoral component and all-poly tibia) were included in the 1.5-stage cohort. Patients who underwent a 2-stage reimplantation procedure were included in the 2-stage cohort. Outcomes included visual analog scale pain scores, 90-day emergency department visits, 90-day readmission, unplanned reoperation, reinfection, as well as cost at 1 and 2-year intervals. A total of 116 patients were included for analyses. ResultsThe 90-day pain scores were lower in the 1.5-stage cohort compared to the 2-stage cohort (2.9 versus 4.6, P = .0001). There were no significant differences between readmission and reoperation rates. Infection clearance was equivalent at 79.3% for both groups. Two-stage exchange demonstrated an increased cost difference of $26,346 compared to 1.5-stage through 2 years (P = .0001). Regression analyses found 2 culture-positive results with the same organism decreased the risk for reinfection [odds ratio: 0.2, 95% confidence interval 0.04-0.8, P = .03]. ConclusionFor high-risk candidates, articulating spacers can preserve knee function, reduce morbidity from second-stage surgery, and lower the costs with similar rates of infection clearance as 2-stage exchange.
