Ankle fracture surgery in patients experiencing homelessness: a national evaluation of one-year rates of reoperation.

To evaluate the impact of homelessness on surgical outcomes following ankle fracture surgery. Retrospective cohort study. Mariner claims database. Patients older than 18 years who underwent open reduction and internal fixation (ORIF) of ankle fractures between 2010 and 2021. A total of 345,759 patients were included in the study. Study patients were divided into two cohorts (homeless and nonhomeless) based on whether their patient record contained International Classification of Disease (ICD)-9 or ICD-10 codes for homelessness/inadequate housing. One-year rates of reoperation for amputation, irrigation and debridement, repeat ORIF, repair of nonunion/malunion, and implant removal in isolation. Homeless patients had significantly higher odds of undergoing amputation (adjusted odds ratio [aOR] 1.59, 95% confidence interval [CI] 1.08-2.27, P = 0.014), irrigation and debridement (aOR 1.22, 95% CI 1.08-1.37, P < 0.001), and repeat ORIF (aOR 1.16, 95% CI 1.00-1.35, P = 0.045). Implant removal was less common in homeless patients (aOR 0.65, 95% CI 0.59-0.72, P < 0.001). There was no significant difference between homeless and nonhomeless patients in the rate of nonunion/malunion repair (aOR 0.87, 95% CI 0.63-1.18, P = 0.41). Homelessness is a significant risk factor for worse surgical outcomes following ankle fracture surgery. The findings of this study warrant future research to identify gaps in surgical fracture care for patients with housing insecurity and underscore the importance of developing interventions to advance health equity for this vulnerable patient population. Prognostic Level III.

The Efficacy and Safety of Radiation-Free Retrograde Intrarenal Surgery: A Prospective Multicenter-Based, Randomized, Controlled Trial.

Fluoroscopy is usually required during retrograde intrarenal surgery (RIRS). Although fluoroscopy is considered necessary for effective and safe RIRS, there is growing awareness regarding radiation exposure risk to patients and surgeons. We conducted a multicenter-based, randomized, controlled trial to compare the safety and effectiveness of radiation-free (RF) RIRS with radiation-usage (RU) RIRS for kidney stone management. From August 2020 to April 2022, patients with a unilateral kidney stone (≤20 mm) eligible for RIRS were prospectively enrolled in 5 tertiary medical centers after randomization and divided into the RF and RU groups. RIRS was performed using a flexible ureteroscope with a holmium:YAG laser. The primary end point of this study was the success rate, defined as complete stone-free or residual fragments with asymptomatic kidney stones ≤ 3 mm. The secondary end point of this study was ascertaining the safety of RF RIRS. The success rates were analyzed using a noninferiority test. Of the 140 consecutive randomized participants, 128 patients completed this study (RF: 63; RU: 65). The success rates (78% vs 80%, P = .8) were not significantly different between the groups. The rate of high-grade (grade 2-4) ureter injury was not significantly higher in the RF group compared to the RU group (RF = 3 [4.8%] vs RU = 2 [3.1%], P = .6). In RF RIRS, the success rate was noninferior compared to RU RIRS (the difference was 2.2% [95% CI, 0.16-0.12]). This study demonstrated that the surgical outcomes of RF RIRS were noninferior to RU RIRS.

Extended Endoscopic Endonasal Approach for Giant Pediatric Craniopharyngiomas: Technical Note and Case Series.

Giant pediatric craniopharyngiomas are rare tumors whose clinical and surgical management is extremely challenging. A variety of open transcranial approaches has been used to resect these lesions. Although there has been an increasing acceptance of the endoscopic endonasal approach (EEA) for the resection of pediatric craniopharyngiomas in recent years, many surgeons continue to recommend against the use of the EEA for giant pediatric craniopharyngiomas. This study aimed to evaluate the feasibility of extended EEA for giant craniopharyngiomas in the pediatric population. All consecutive pediatric patients with giant craniopharyngiomas (diameter >4 cm) who underwent endoscopic endonasal surgery at our institution were retrospectively reviewed. Data on demographic information, preoperative assessment, imaging features, surgical results, complications, and recurrences were recorded and analyzed. A total of 16 pediatric patients with an average age of 12 years were identified. The mean maximum diameter and volume of the tumors were 4.35 cm and 24.1 cm3, respectively. Gross total resection was achieved in 13 patients (81.3%) and subtotal resection in 3 patients (18.7%). Postoperatively, partial or complete anterior pituitary insufficiency occurred in 100% of patients, and 62.5% developed new-onset diabetes insipidus. Visual function improved in 9 patients (56.3%) and remained stable in 7 patients (43.7%). Postoperative cerebrospinal fluid leakage occurred in 2 patients and was successfully repaired through the EEA. During a mean follow-up of 44.3 months, 18.8% of patients had a >9% increase in body mass index, and 93.8% of patients successfully returned to school or work. Two patients (12.5%) suffered a recurrence. Disease control was achieved in 16 patients (100%) at final follow-up. The extended EEA allows adequate access to this challenging tumor and enables complete resection and visual improvement with a reasonable approach-related complication rate.

Handmade Loop Versus Hem-o-Lok Clip in Closure of Appendiceal Stump During Laparoscopic Appendectomy: Limited Setting in a Peripheral University Hospital.

Background: Today, laparoscopy is frequently used in abdominal emergencies such as acute appendicitis. There are several techniques used to close the appendiceal stump during laparoscopic appendectomy. We aimed to compare the use of handmade loop and Hem-o-lok used to close the appendiceal stump in public hospitals where resources are limited, in terms of surgical outcomes and cost. Methods: Between January 2020 and December 2022, patients for whom handmade loops and Hem-o-loks were used to close the appendiceal stump during laparoscopic appendectomy in our clinic were included in the study. There were a total of 638 patients (mean age: 33 ± 13.5 years, 325 females and 313 males) in the patient cohort. Demographic and clinical data, duration of surgery, complications, hospital stay, pathology reports, mortality, and cost of supplies were compared between the two groups. Results: There were 308 patients in the handmade loop group (160 females, 148 males, mean age: 33.7 years, range: 18-85 years) and 330 patients in the Hem-o-lok group (166 females, 164 males, mean age: 32.5 years, range: 18-89 years). There was no significant difference between the two groups for American Society of Anesthesiologists score, duration of symptom, hospital stay, intensive care unit stay, preoperative laboratory values, histopathological results, mortality, and morbidity (P > .05). The mean operation time was 48.76 ± 16.16 minutes in the handmade loop group and 40.53 ± 11.63 minutes in the Hem-o-lok group (p = 0.001). In terms of cost, the cost per case of Hem-o-lok group was about 25.8 times as much as the group that used sutures ($31 versus $1.2). Conclusions: Both methods can be used safely in laparoscopic appendectomy. The use of Hem-o-lok has no advantage other than shortening the operation time. However, it is costlier. Especially in peripheral hospitals where resources are limited, closing the appendiceal stump using a handmade loop is an easy, safe, and cost-effective method.

Teaching of manual cataract extraction in ophthalmic surgical training programmes.

Manual cataract extraction techniques such as extracapsular cataract extraction (ECCE) or manual small incision cataract (MSICS) surgery have been replaced by phacoemulsification cataract surgery. Surgical training opportunities for manual techniques of cataract extraction are limited in modern surgical training programmes. This study evaluated the current trends of ECCE/MSICS training opportunities amongst trainees and trainers in the Irish Ophthalmic Surgical Training Program. An electronic survey was distributed to all ophthalmic surgical trainees and consultants in the country. It addressed the experience and exposure to ECCE/MSICS. Nineteen of 33 (57%) trainees and 29 of 55 (55%) of consultants completed the survey. Twelve of 19 (63%) trainees viewed an ECCE procedure performed live. Twenty-seven of 29 (93%) consultants performed an ECCE procedure during their surgical career; 8 of 27 (30%) performed an ECCE within the last 1-3 years. Fourteen of 19 (74%) trainees stated they do not feel confident converting from phacoemulsification to ECCE independently. Sixteen of 19 (89%) trainees believe manual cataract extraction training should be included in their surgical training. Nineteen of 29 (65%) consultants believe training in manual cataract extraction should be part of the surgical training programme. There is a paucity of manual cataract extraction being performed in Ireland, limiting live surgical training in this technique. This survey highlights the limited experience of trainees in this valuable skill that is occasionally required for a successful surgical outcome. The authors conclude that wet laboratory simulated training of manual cataract extraction will bridge this gap.

Accelerating Fleur-de-lis Panniculectomy with the Absorbable Dermal Stapler-A Study of Efficiency, Aesthetics, and Quality-of-life.

Fleur-de-lis panniculectomy (FDL), a contouring technique involving vertical and horizontal tissue resections, often involves longer operative times and potential complications. This study assessed operative time, postoperative outcomes, and patient-reported quality of life (PRO) with Insorb® Absorbable Subcuticular Skin Stapler versus traditional sutures during FDL. A retrospective review from 2015 to 2022 of FDL patients excluded those with complex concomitant procedures. Demographics, operative details, and surgical outcomes were compared between patients using the dermal stapler and those with suture-only closures. Forty subjects were identified, with 25 (62.5%) in the dermal stapler cohort. The dermal stapler significantly reduced total procedure time (66.76 vs. 125.33 min, p < 0.05). There were no significant differences in surgical site occurrences, aesthetic outcomes, readmissions, or reoperations. Multivariate regression analysis further highlighted the choice of closure technique as an independent predictor of operative time, with traditional sutures indicating a significantly increased operative time compared to using the dermal stapler (AOR 76.53, CI 38.11-114.95, p < 0.001). Regarding PROs, both groups saw improvements across multiple BODY-Q domains, but the dermal stapler group reported greater enhancements (six out of nine domains vs. three for sutures). The absorbable dermal stapler significantly reduces FDL operative time without increasing wound healing or aesthetic dissatisfaction incidents and maintains comparable quality-of-life improvements to standard suture closure.

Impact of Neoadjuvant Chemoimmunotherapy on Surgical Outcomes and Time to Radiation in Triple-Negative Breast Cancer.

We examined the association between immunotherapy-containing and standard chemotherapy regimens with treatment delays and postoperative complications in stage II-III triple-negative breast cancer. The effect of immune-related adverse events (irAEs) was compared. We compared 139 women treated with neoadjuvant pembrolizumab plus chemotherapy (KEYNOTE-522 regimen) from August 2021 to September 2022 with 287 consecutive patients who received neoadjuvant chemotherapy alone prior to July 2021 and underwent surgery. Baseline characteristics, time to treatments, and surgical complications were compared using two-sample non-parametric tests. Linear regression evaluated association of irAEs with time to surgery and radiation. Logistic regression identified factors associated with surgical complications. Age, body mass index, race, American Society of Anesthesiologists (ASA) class, and mastectomy rates were similar among cohorts. No clinically relevant difference in time from end of neoadjuvant treatment to surgery was observed [KEYNOTE-522: median 32 (IQR 27, 43) days; non-KEYNOTE-522: median 31 (IQR 26, 37) days; P = 0.048]. Time to radiation did not differ (P = 0.7). A total of 26 patients (9%; non-KEYNOTE-522) versus 11 (8%; KEYNOTE-522) experienced postoperative complications (P = 0.6). In the KEYNOTE-522 cohort, 59 (43%) of 137 patients experienced 82 irAEs; 40 (68%) required treatment. Older age (P = 0.018) and ASA class 4 (P = 0.007) were associated with delays to surgery after adjusting for clinical factors. Experiencing ≥ 1 irAE was associated with delay to radiation (P = 0.029). IrAEs were not associated with surgical complications (P = 0.4). We observed no clinically meaningful difference between times to surgery/adjuvant radiation or postoperative complications and type of preoperative chemotherapy. IrAEs were associated with delay to adjuvant radiation but not with postoperative complications or delay to surgery.

Posterior Corrective Surgery for Type II Congenital Kyphosis: SRS-Schwab Grade 4 Osteotomy or Vertebral Column Resection?

Surgical decision-making for congenital kyphosis (CK) with failure of anterior segmentation (type II) has been contradictory regarding the trade-off between the pursuit of correction rate and the inherent risk of the osteotomy procedure. This study was designed to compare the clinical and radiographic measurement in type II CK underwent SRS-Schwab Grade 4 osteotomy and vertebral column resection (VCR), the most-adapted osteotomy techniques for CK, and to propose the strategy to select between the two procedures. This retrospective observational comparative study evaluated surgical outcomes in type II CK patients underwent VCR or SRS-Schwab Grade 4 osteotomy at our institution between January 2015 and January 2020. Patients operated with VCR and SRS-Schwab Grade 4 osteotomy were allocated to Group 1 and Group 2 respectively. Radiographic parameters and SRS-22 quality of life metrics were assessed at pre-operation, post-operation, and during follow-up visits for both groups, allowing for a comprehensive comparison of surgical outcomes. Thirty-one patients (19 patients in Group 1 and 12 patients in Group 2) aged 16.3 ± 10.4 years were recruited. Correction of segmental kyphosis was similar between groups (51.1 ± 17.6° in Group 1 and 48.4 ± 19.8° in Group 2, p = 0.694). Group 1 had significantly longer operation time (365.9 ± 81.2 vs 221.4 ± 78.9, p < 0.001) and more estimated blood loss (975.2 ± 275.8 ml vs 725.9 ± 204.3 mL, p = 0.011). Alert event of intraoperative sensory and motor evoked potential (SEP and MEP) monitoring was observed in 1 patient of Group 2. Both groups had 1 transient post operative neurological deficit respectively. SRS-Schwab Grade 4 osteotomy was suitable for kyphotic mass when its apex is the upper unsegmented vertebrae or the neighboring disc, or when the apical vertebrae with an anterior/posterior (A/P) height ratio of vertebral body higher than 1/3. VCR is suitable when the apex is located within the unsegmented mass with its A/P height ratio lower than 1/3. Proper selection of VCR and SRS-Schwab Grade 4 osteotomy according to our strategy, could provide satisfying radiographic and clinical outcomes in type II CK patients during a minimum of 2 years follow-up. Patients undergoing VCR procedure might have longer operation time, more blood loss and higher incidence of peri- and post-operative complications.

ANTEGRADE METHODS OF BILIARY DECOMPRESSION IN TUMOR OBSTRUCTION OF THE BILIARY TRACT

Percutaneous transhepatic endoscopic ultrasound-guided intervention is a crucial method for addressing mechanical jaundice. This technique for restoring bile outflow enables the resolution of several medical and diagnostic issues with minimal invasiveness and fewer complications compared to traditional open surgical treatments. Most often, antegrade cholangiostomy is used in oncological practice, where the variety of clinical situations determines the indications for performing this intervention in different variants and with different goals. According to the world literature, at the moment, sufficient experience of transdermal technologies has been accumulated, their application in clinical practice has been worked out, which allows to recognize them, to a certain extent, as routine. The purpose of this work is to optimize biliary decompression in patients with tumor obstruction of the biliary tract, to improve the prevention of complications, to enhance the immediate results of treatment and the quality of life for this group of population. The study analyzed the examination and surgical treatment outcomes of 64 patients with tumor-related mechanical jaundice treated in surgical hospitals from 2017 to 2023. All patients underwent antegrade biliary drainage procedures, specifically percutaneous transhepatic cholangiostomy and bile duct stenting under ultrasound guidance, to achieve biliary decompression. Percutaneous transhepatic endoscopic interventions have become the primary method for biliary decompression in cases of bile duct obstruction due to tumors. These procedures, particularly for malignant tumors, are associated with relatively few complications and low mortality rates.

Surgical Treatment Outcomes of Anterior-Only Correction and Reconstruction for Severe Cervical Kyphotic Deformity with Neurofibromatosis-1: A Retrospective Study with a 5-Year Follow-Up.

Currently, anterior-only (AO), posterior-only, and combined anterior-posterior spinal fusions are common strategies for treating cervical kyphosis in patients with neurofibromatosis-1 NF-1. Nevertheless, the choice of surgical strategy remains a topic of controversy. The aim of our study is to evaluate the safety and effectiveness of anterior decompression and spinal reconstruction for the treatment of cervical kyphosis in patients with NF-1. Twelve patients with NF-1-associated cervical kyphotic deformity were reviewed retrospectively between January 2010 and April 2020. All patients underwent AO correction and reconstruction. The X-ray was followed up in all these patients to assess the preoperative and postoperative local kyphosis angle (LKA), the global kyphosis angle (GKA), the sagittal vertical axis, and the T1 slope. The visual analog scale score, Japanese Orthopedic Association (JOA) score, and neck disability index (NDI) score were used to evaluate the improvement inclinical symptoms. The results of the difference in improvement from preoperatively to the final follow-up assessment were assessed using a paired t-test or Mann-Whitney U-test. The LKA and GKA decreased from the preoperative average of 64.42 (range, 38-86) and 35.50 (range, 10-81) to an average of 16.83 (range, -2 to 46) and 4.25 (range, -22 to 39) postoperatively, respectively. The average correction rates of the LKA and GKA were 76.11% and 111.97%, respectively. All patients had achieved satisfactory relief of neurological symptoms (p < 0.01). JOA scores were improved from 10.42 (range, 8-16) preoperatively to 15.25 (range, 11-18) at final follow-up (p < 0.01). NDI scores were decreased from an average of 23.25 (range, 16-34) preoperatively to an average of 7.08 (range, 3-15) at the final follow-up (p < 0.01). Anterior-only correction and reconstruction is a safe and effective method for correcting cervical kyphosis in NF-1 patients. In fixed cervical kyphosis cases, preoperative skull traction should also be considered.

Clinical analysis of surgical outcome of 89 patients having large cerebral arteriovenous malformations.

The article analyzes the clinical features, morphological characteristics, surgical subtleties and long-term outcome of surgery in 89 cases of 'large' sized AVMs. During the period 2004 to 2022, 89 cases of 'large' arteriovenous malformations were operated in the neurosurgery departments of the authors. Large AVMs were defined as those that were more than 4cm on either lateral or antero-posterior view of digital subtraction angiogram. The factors that determined the extent of surgical difficulties included site and eloquence of the area, number of feeding vascular territories and draining veins, degree and rate of flow, presence of flow-related aneurysms, and the physical nature of the arteriovenous malformation. There were 59 males and 30 females and the average age was 32 years. Headache, giddiness and convulsions were the common presenting complaints. Six patients were unconscious after surgery. Of these, five patients died in the immediate post-operative period and one patient gradually recovered. Additionally, seven patients developed unilateral limb weakness that included hemiplegia (4 patients) and hemiparesis (3 patients) following surgery. Clinical follow-up ranged from 6 months to 18 years (average 43 months). All surviving patients are leading normal and essentially symptom free life and have recovered from their symptoms of headache, convulsions and giddiness. Large AVMs are amenable to 'curative' surgery with 'acceptable' results. The surgery can be challenging and appropriate case selection that is based on the surgeons experience is vital and decisive.

Circumferential Inferior Vena Cavectomy Without Caval Replacement in the Management of Renal Cell Carcinoma with Tumor Thrombus.

Renal cell carcinoma presents a unique proclivity for vascular involvement giving rise to a peculiar form of locally advanced disease so-called tumor thrombus. To date, the only curative strategy for these cases remains surgery, which should aim to remove every vestige of macroscopic disease. Most of the preexisting literature advocates opening the vena cava to allow tumor thrombus removal and subsequent venous suture closure. However, inferior vena cava circumferential resection (cavectomy) without caval replacement is possible in the majority of cases since progressive occlusion facilitates the development of a collateral venous network aimed at maintaining cardiac preload. Radical nephrectomy with tumor thrombectomy remains a surgical challenge not exempt of operative complications even in experienced hands. In opposition to what traditional cavotomy and thrombus withdrawal can offer, circumferential cavectomy without caval replacement would provide comparable or even better oncologic control, decrease the likelihood of operative bleeding, and prevent the development of perioperative pulmonary embolism. This review focuses on the rationale of circumferential IVC resection without caval replacement and the important technical aspects of this approach in cases of renal cell carcinoma with vascular involvement. We also include an initial report on the surgical outcomes of a contemporary series of patients managed under this approach at our center.

Surgical Management of Norwood Procedure for Atypical Aortic Arch.

Background: Postoperative restenosis of the aortic arch after the Norwood procedure is still an important complication that significantly affects surgical outcomes. The rarity of the Norwood procedure for atypical aortic morphology means appropriate arch reconstruction methods and postoperative complications are still unknown. This study aimed to assess the rate of arch reintervention and clinical outcomes after the Norwood procedure for atypical aortic arch. Methods: This retrospective single-center study was conducted between 2001 and 2022. Sixteen patients were identified, eight with a right aortic arch, five with transposition of the great arteries, one with a right aortic arch and transposition of the great arteries, and two with a large tortuous patent ductus arteriosus connected to the opposite side of the descending aorta. We selected and performed four different surgical techniques depending on each aortic arch morphology. Results: Except for one case, autologous tissue-only arch reconstruction was possible. There was one operative death and four late deaths. Overall, no patients required any surgical or catheter-based reintervention for the aortic arch. On the other hand, left pulmonary artery stenosis due to a narrow subaortic space was found in two patients. Conclusions: The Norwood procedure for atypical aortic arch was performed with good results by choosing the appropriate technique for each morphology. On the other hand, pulmonary artery stenosis is likely to occur especially in the transposition of the great arteries group. Therefore, careful surgical method selection or further improvement of the technique that allows retroaortic space should be considered.

Pilot robotic mastectomy in Singapore (PRoMiSing I) study: first safety and feasibility prospective cohort trial in South East Asia.

Robotic mastectomy has been performed worldwide since 2015. The advantages of the robotic approach in nipple-sparing mastectomy have been proven with better visualization and preservation of blood supply to the nipple-areolar complex (NAC), with a lower incidence of necrosis. It also allows smaller incisions for both mastectomy and immediate breast reconstruction. To date, no centers in Singapore and Southeast Asia offer robotic mastectomy. We believe that robotic mastectomy is a feasible and safe technique that can be utilized by our population. This study aimed to ascertain the surgical outcomes and perform a learning curve analysis in patients undergoing robotic mastectomy in a multi-ethnic South East Asian population. A single arm prospective pilot study of eligible patients aged 21-70 years old with early breast cancer or high-risk patients indicated for risk reducing mastectomy who were eligible and consented for robotic mastectomy were enrolled in this trial from 22nd December 2022 to 15th December 2023. A total of 29 consecutive robotic mastectomies were performed. The mean total operative time was 95±10.2 minutes. The average blood loss was 5.7±1.9ml and the average length of stay was 1.05 days. The mean mastectomy specimen weight was 251 g, and there was no conversion to conventional mastectomy in any case. Furthermore, there were no 30-days morbidity or complications in terms of wound infection requiring intervention, flap and nipple-areolar complex (NAC) necrosis, and postoperative hematoma/bleeding requiring intervention. This study contributes to the current evidence that robotic mastectomy is a safe and feasible option, and could prove to be a great alternative to conventional mastectomy. Further prospective trials examining the long-term oncological outcomes of robotic mastectomy will be performed to establish the oncologic safety of this technique in breast cancer treatment.

The Effect of Neoadjuvant Systemic Therapy on Surgical Outcomes After Lymph Node Dissections for Stage III Melanoma; An Australian Cohort.

Neoadjuvant systemic therapy (NAST) for patients with stage III melanoma achieves high major pathologic response rates and high recurrence-free survival rates. This study aimed to determine how NAST with targeted therapies (TTs) and immune checkpoint inhibitors (ICIs) influences surgical outcomes after lymph node dissection in terms of complications, morbidity, and textbook outcomes. Patients who underwent a lymph node dissection after either NAST in a clinical trial or upfront surgery for stage III melanoma between 2014 and 2022 were identified from an institutional research database. The study included 89 NAST-treated patients and 79 upfront surgery-treated patients. The rate of postoperative complications did not differ between the NAST- and upfront surgery-treated patients (55% vs. 51%; p = 0.643), and steroid treatment for drug toxicity did not influence the complication rate (odds ratio [OR], 1.1; 95% confidence interval [CI], 0.4-3; p = 0.826). No significant differences in postoperative morbidity were observed in terms of seroma (23% vs. 11%; p = 0.570) or lymphedema (36% vs. 51%; p = 0.550). The rate of achievinga textbook outcome was comparable for the two groups (61% vs. 57%; p = 0.641). The surgical outcomes after lymph node dissections were comparable between the patients who received NAST and those who had upfront surgery, indicating that surgery can be safely performed after NAST with TT or ICI for stage III melanoma.

Choanal Atresia: Clinical Features and Factors Affecting Its Surgical Outcomes

Introduction: One of a rare congenital anomaly seen in the development of nose is choanal atresia, whose occurrence is 1 in 5000-8000 live births. This study highlights our experiences in the management of choanal atresia. Materials and methods: It is a retrospective study, which includes the systematic analysis of case files of patients who underwent surgical treatment for choanal atresia from the year 2015 to 2022. Results: Total of 11 cases (15 operated sides) which has 9 female (53%) and 8 male (47%). Majority of them were bony atretic plate (10) followed by mixed variety (5) and none purely membranous. Age at 1st surgery in bilateral cases ranged from 6th day of life to 18th day of life. For unilateral cases the age at 1st surgery ranged from 26th day of life to as late as 10 years old. Conclusion: Management of choanal atresia involves multi-disciplinary approach and preventing restenosis is a challenge. Factors effecting the outcome of surgery are age and weight of the child, as bigger the child in size, wider the choanal arches can be opened with less post-operative scarring and restenosis. Usage of nasopharyngeal airway as a stent in primary repair during early post-operative period is essential to stabilize the nasal airway.

Outcomes of surgical repair of Type III and IV laryngotracheoesophageal clefts with posterior cartilage grafting.

To describe the clinical outcomes of patients who underwent surgical repair through an anterior approach that involved interposition a posterior cartilage for Type III or Type IV laryngotracheoesophageal cleft (LTEC). A chart view was performed on patients with Type III or Type IV LTEC between May 2017 and May 2022. Demographic features and surgical outcomes were collected and analyzed. Seven patients were finally included. Five patients were diagnosed with Type III LTEC and two patients were diagnosed with Type IV LTEC. All but one patients survived and thrived. Four patients were able to successfully extubate with acceptable voice, and two patients were tracheostomized. Five patients were deemed safe for all consistencies food and one was safe for thickened food. After a mean follow-up of 49months (18-83months), neither complications nor recurrences were observed. An anterior laryngofissure approach to the cleft repair with a posterior cartilage grafting is an effective and safe treatment for Type III or IV LTEC, which enables closure of LTEC and reconstruction of cricoid plate in order to avoid tracheoesophageal fistula formation or subglottic stenosis postoperatively. Severe tracheomalacia and GERD are two main causes for surgical failure.

Retroauricular endoscopic thyroidectomy: initial single-institution experiences.

Conventional thyroidectomy often results in visible scarring postoperatively. Endoscopic thyroidectomy offers the advantage of scarless surgery, especially beneficial for young adult women. The retroauricular approach uses a facelift incision well-known among surgeons and eliminates the need for gas insufflation due to the large working space. An early retrospective analysis was conducted on thirty-one individuals who underwent gasless retroauricular endoscopic thyroidectomy approach, focusing on isthmolobectomies (n = 26) and lobectomies (n = 5), with one case necessitating conversion to open thyroidectomy, from January 2016 to April 2017. Physical examination, laboratory, and histopathology findings were collected. The scar was evaluated using the Vancouver Scale System, while other surgical and oncological outcomes were documented and assessed. The average operative time was 154.2 ± 21.3min, with an average bleeding volume of 69.2 ± 52.1mL. The average length of stay was 4.7 ± 2.2days. All complications occurred were temporary and all subjects remained in good condition throughout the follow-up period. Most subjects (65.6%) were very satisfied with the scar concealed in the retroauricular area. Retroauricular endoscopic thyroidectomy is a safe and feasible remote access technique with excellent postoperative results.
