DIFFERENTIAL APPROACH IN THE COMBINED SURGICAL TREATMENT OF VARICOSE VEINS OF THE LOWER EXTREMITIES ACCORDING TO THE RESULTS OF ULTRASOUND DOPPLER ULTRASOUND

The most common pathology of the lower extremity veins is varicose veins, which is an urgent medical and social problem. The number of patients with trophic disorders is not decreasing, despite the improvement of treatment methods, which leads to a deterioration in the quality of life. Therefore, the topic of introducing new and improving existing minimally invasive treatment methods is relevant and requires further research. According to international studies, the combined laser method of treatment is superior in terms of therapeutic and cosmetic results to all known methods of surgical treatment of varicose veins and can be used in most cases.Aim. To demonstrate the eff ectiveness of individual diff erentiated combined surgical techniques for the treatment of varicose veins of the lower extremities, taking into account the data of ultrasound preoperative and intraoperative navigation.Material and methods. The study included 246 patients with varicose veins of the lower extremities of class C2-C5, who had various variants of varicose veins of the lower extremities – saphenous varicose veins in the system of small and/or large saphenous veins, which in some patients was combined with varicose veins in the basin of non-saphenous veins and reticular varicose veins. Patients were divided into clinical groups due to the diff erence in surgical and tactical treatment approach. All patients underwent preoperative ultrasound Doppler ultrasonography (USG) of the lower extremity veins in horizontal and vertical positions. The patency of deep and saphenous veins, the presence of unable varicose dilated saphenous venous tributaries with an assessment of the aff ected basin (saphenous, non-saphenous varicose veins and combined forms) were assessed. Horizontal and vertical pathological venous refl uxes were detected. All patients underwent combined surgical intervention – EVLC and miniphlebectomy under ultrasound Doppler monitoring, and sclerotherapy as indicated. The observation period lasted 1.5 years for each patient.Research results and discussion. The assessment of the treatment results was based on the presence of patient complaints, analysis of the clinical picture, the presence or absence of complications during the observation period, recurrence of the disease during the observation period, and analysis of the ultrasound assessment of the veins by an ultrasound diagnostician during a dynamic examination. USG was mandatorily performed in patients of all groups before surgical treatment, during surgical correction and as a control within 1-3 days after surgery. Dynamic follow-up was performed in all patients at 1, 3, 6 and 12-18 months after surgical treatment.Conclusions. Most patients have a complete recovery after surgical treatment. Careful history taking in patients of this group and performance of ultrasound Doppler ultrasonography of the veins of the lower extremities allowed to choose an eff ective individual surgical treatment. Specialists’ understanding of the capabilities of ultrasound Doppler ultrasound of the veins of the lower extremities, as well as compliance with the full examination protocol for ultrasound Doppler veins, allows us to provide detailed information to determine the most eff ective treatment tactics and prevent complications of the disease.

Surgical treatment of breast cancer related lymphedema-the combined approach: a literature review.

Breast cancer therapy is a common cause of lymphedema, a chronic condition resulting from impaired fluid drainage through the lymphatic system. The accumulation of fluid in the affected limb leads to swelling, inflammation, and fibrosis, causing irreversible changes. While conservative therapy is the initial treatment for lymphedema, it may prove ineffective for advanced-stage cases that require surgical intervention. Physiological approaches such as lymphaticovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT) aim to restore lymphatic circulation, while reductive approaches such as excision of excess tissue and liposuction (LS) aim to eliminate fibrofatty tissue. In advanced stages of breast cancer-related lymphedema, a treatment that incorporates both physiological and reductive methods is advantageous. The timing of these approaches varies, and recent simultaneous procedures have been introduced to address both aspects in one surgery. Additionally, lymphedema treatment can be combined with breast reconstruction. Current imaging techniques provide a better assessment of the lymphedematous limb, aiding in the tailoring of a personalized combined approach within a single surgery. This study aims to review the combined approach for breast cancer-related lymphedema treatment and propose a new therapeutic algorithm based on recent literature. The research aims to optimize the management of breast cancer-related lymphedema and improve patient outcomes. PubMed/MEDLINE was used as the database to conduct a review of the currently available literature concerning combined surgical techniques for treating breast cancer related lymphedema (BCRL). In our review, we discuss imaging methods for assessing lymphatic system anatomy and function in surgical preparation and decision-making. Simultaneously, we examine a range of combined surgical techniques for treating BCRL, encompassing the combined physiologic approach, breast reconstruction with physiologic surgery, and the combination of reductive and physiologic procedures. Our emphasis remains on key parameters, including patient demographics, lymphedema staging, procedure types, follow-up duration, and objective limb measurements. Surgical treatment of BCRL can include several surgical modalities that can be performed simultaneously. Current imaging techniques enable the tailoring of a personalized combined one-stage surgery for BCRL patients.

Descemet Membrane Endothelial Keratoplasty in Corneal Endothelial Decompensation After a Forceps-Induced Corneal Birth Injury: Case Series and Technique

Purpose: The aim of this study was to describe the efficacy of Descemet membrane endothelial keratoplasty (DMEK) in patients with corneal endothelial decompensation secondary to a forceps-induced corneal birth injury. Methods: This was a retrospective, noncomparative, interventional case series. Four eyes of 4 patients (1 female and 3 males; mean age, 64.0 ± 4.7 years) with corneal endothelial decompensation due to forceps-induced corneal birth injury were included. DMEK was performed in all cases, using a combined technique, including the use of intraoperative optical coherence tomography, vital staining of Descemet membrane of both host and donor, removal of scarred Descemet membrane with side-port forceps and vitreous cutter to smoothen the posterior corneal surface, epithelial peeling, and illumination for visualization. The examination included preoperative and postoperative ophthalmologic examinations: best-corrected visual acuity (converted to logarithm of the minimum angle of resolution [logMAR]), intraocular pressure, endothelial cell density (ECD), and central corneal thickness. Results: No postoperative complications were noted, and corneal transparency was maintained during follow-up (mean follow-up period, 32.0 ± 27.0 months; range, 3–71 months). The mean best-corrected visual acuity was 0.52 ± 0.35 logMAR preoperatively and 0.15 ± 0.09 logMAR at the last visit. The mean postoperative ECD was 1632 ± 631 cells/mm2 (mean ECD at baseline, 3167 cells/mm2). Central corneal thickness decreased from 640 ± 67 μm preoperatively to 576 ± 58 μm postoperatively. Conclusions: This study suggests that DMEK can be performed uneventfully in eyes with a forceps-induced corneal birth injury. The combination of surgical techniques may be an effective approach for DMEK.

Treatment of deep single RT2 and RT3 antero-mandibular gingival recessions with a combination of surgical techniques: A case series study.

To evaluate root coverage (RC) in deep single antero-mandibular RT2 and RT3 gingival recessions (GR) and to investigate the influence of several factors in RC. Fifteen single antero-mandibular GR with a minimum depth of 3 mm were consecutively treated with a new one-stage technique (laterally positioned flap with a tunnel access and a connective tissue graft). At baseline and at 12-month follow-up, the percentage of mean root coverage (%MRC), the recession reduction (RecRed), complete root coverage (CRC) and the gain of keratinized tissue width (KTW) were assessed. Descriptive, intergroup comparative and correlation analyses were performed. At 12 months, a %MRC of 77.29 ± 21.48% with a mean RecRed of 4.10 ± 1.51 mm was achieved. The %MRC was 84.71 ± 21.08% in RT2, and 62.43 ± 14.17% in RT3. The mean gain of KTW was 2.10 ± 0.89 mm, with a mean gain of 2.0 ± 1.03 mm for RT2 and 2.3 ± 0.57 mm for RT3. CRC was observed in six cases, all of them being RT2. A positive association was found between the %MRC and the initial position of the tooth and of both papillae. This technique might be a valuable approach for the treatment of deep single antero-mandibular RT2 and RT3 recessions, even in malpositioned teeth. A combination of different surgical techniques could provide greater vascularization to the CTG especially in malpositioned teeth in sextant V with a large avascular area to be covered.

Gynecomastia - a literature review of management, diagnosis and treatment

Introduction and Purpose: Gynecomastia is a common clinical problem that can also be a symptom of many serious disorders. The aim of this study is to analyze the etiology, pathogenesis, diagnostics, as well as pharmacological and surgical treatment, while also addressing the psychological aspect of the condition. State of Knowledge: Gynecomastia is the development of noncancerous breast tissue in males. It can occur unilaterally or bilaterally and may cause pain. It can be a natural occurrence during infancy, adolescence, and and in older age. It is usually accompanied by an imbalance between estrogens and androgens. Hormonal disorders lead to the growth of stromal and ductal proliferation. In the diagnostic process, the most important aspect is establishing the cause of the condition, allowing for the implementation of appropriate treatment. Gynecomastia can cause a decrease in quality of life, depression, anxiety, and reduced self-esteem. Conclusions: Gynecomastia is a complex condition that requires an individualized approach to the patient. It can be a side effect of medication use, result from an underlying disease, or occur idiopathically. Surgical treatment forms the basis of the therapeutic process. Currently, combined surgical techniques are most commonly used to achieve the best cosmetic effect.

Imaging findings and clinical function after combined surgery for recurrent patella dislocation: a comparative study

Limited research has evaluated imaging results following a combination of operations for recurrent patella dislocation (RPD) based on medial patellofemoral ligament (MPFL) reconstruction. Therefore, this study aimed to retrospectively compare the imaging and clinical results of RPD following 2 types of combined surgical techniques. Patients who underwent combined surgery for RPD from January 2008 to December 2019 were enrolled in the study and allocated into 2 groups. MPFL reconstruction combined with lateral retinacular release (LRR) was performed in groups A and B, and an additional tibial tuberosity transfer (TTT) was performed in group B only. Patients in group A with a tibial tuberosity trochlear groove (TT-TG) distance greater than 15 mm were included in subgroup A*. Congruence angle (CA), patellar tilt angle (PTA), lateral patellofemoral angle (LPA), lateral patellar displacement (LPD), TT-TG, Insall-Salvati Index (ISI), the Dejour type of trochlear dysplasia, and knee function were assessed. All groups were followed up in the short-term (1-2 years), and group B was also followed up in the mid-term (over 5 years). A total of 40 knees (36 patients) were included in group A, 26 knees (24 patients) in subgroup A*, and 27 knees (26 patients) in group B. In group A, CA, PTA, and LPD had increased at the short-term follow-up, yet LPA had decreased compared to the results 3 days after surgery. In group B, at the mid-term follow-up, PTA (12.54±6.88 vs. 15.23±6.10; P=0.002) increased while LPD (7.08±6.48 vs. 4.69±6.28; P=0.049) decreased compared with the short-term outcomes. The more severe the femoral trochlear dysplasia, the lower the mid-term Kujala scores in group B (P=0.007). The short-term TT-TG (17.32±4.288 vs. 12.84±3.758; P<0.001) and ISI [1.25 (1.1075, 1.300) vs. 1.06 (1.00, 1.16); P<0.001] in group B were lower than those in group A, who had a higher Kujala score (P<0.001). The CA, LPD, ISI, TT-TG, and Kujala score in subgroup A* were higher than those in group B at the short-term follow-up (P<0.05). Both types of combination treatments were successful in altering the patellofemoral joint in a satisfactory manner, and the knee function improved in both groups. A TTT might not be necessary for patients with a TT-TG distance greater than 15 mm.

Etiology and Treatment of Peri-Implant Soft Tissue Dehiscences: A Narrative Review.

Implant soft tissue dehiscences compromise not only the aesthetics of the supported restorations but implant survival in the long run. The aim of this narrative review was to briefly present the causative factors of buccal peri-implant soft tissue dehiscences (PSTDs), how these are classified, and the current therapeutic approaches. Implant malposition and the thin peri-implant phenotype are the two major determinants for the occurrence of PSTDs, but other risk factors have also been identified. The most common surgical procedure for treating PSTDs is the split-thickness coronally advanced flap combined with either a connective tissue graft or acellular dermal matrix materials. However, depending on the class and subtype of the dehiscence, the combination of surgical techniques with modifications in the restoration may further ameliorate the final result. In general, within a five-year follow-up period, most techniques lead to a satisfactory aesthetic result, although full coverage of the implant/abutment surface is not always achievable, especially in more extended lesions.

Intrathoracic Giant Mass with Anomalous Vascular Origin in an Asymptomatic Patient: A Case Report

Diagnostic and surgical difficulties were presented in case of a giant mass, found incidentally, in a 65-year-old healthy and asymptomatic man. The patient underwent different diagnostic procedures. Surgery was the treatment of choice. A combination of both open technique and videothoracoscopy to reduce the risk of seeding, pending a certain diagnosis, was resolutive. The postoperative period and recovery time were uneventful. The patient was discharged on the 5th postoperative day. The histological diagnosis was benign schwannoma. There are different aspects to think about, based also on the experience of each center. According to our experience, this is a rare situation; the combined surgical techniques to control the vascular risk and tissue infiltration of the mass seemed to us the approach of choice.

Outcomes, Union Rate, and Complications After Operative and Nonoperative Treatments of Neer Type II Distal Clavicle Fractures: A Systematic Review and Meta-analysis of 2284 Patients

Background: As nonoperative treatment of Neer type II distal clavicle fractures is associated with nonunion rates up to 33%, operative treatment is frequently advocated. However, evidence is lacking regarding which operative treatment to perform and whether this is superior to nonoperative treatment in terms of functional outcome and complication rate. Purpose: (1) To evaluate which surgical technique in the treatment of Neer type II distal clavicle fractures is optimal with regard to patient-reported outcomes and union and complication rates. (2) To review nonoperatively treated patients. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review of the literature and meta-analysis were performed on January 27, 2021, in PubMed, Embase, CENTRAL, CINAHL/EBSCO, Web of Science/Clarivate Analytics, and SPORTDiscus/EBSCO. The search included all studies regarding nonoperative and operative treatment of Neer type II distal clavicle fractures with a minimum of 20 patients and follow-up of 12 months. The primary and secondary outcomes were patient-reported outcome measures at 12 months and union, complication, and revision rates. Results: A total of 59 articles were included involving 2284 patients. Coracoclavicular fixation, hook plate, transacromial pins, alternative plate, tension band wire/K-wire, a combination of surgical techniques, and a nonoperative group were described. Hook plates showed lower Constant-Murley scores as compared with coracoclavicular fixation (standard mean difference, –0.77; 95% CI, –1.26 to –0.28; P = .002). However, no significant difference was seen when the hook plate was compared with the locking plate and tension band wire/K-wire groups, and no significant difference in union rate was seen among all operative treatment groups. Operatively treated patients had significantly higher union rates than patients treated nonoperatively (standard mean difference: 0.05; 95% CI, 0.01 to 0.37; P = .004). Conclusion: Patients treated with hook plates showed significantly lower Constant-Murley scores and higher complication and revision rates as compared with those treated with coracoclavicular fixation, without differences in union rate. Higher Constant-Murley scores were seen in those patients with supplemental coracoclavicular fixation when using locking. Nonoperatively treated patients showed good functional outcome despite the 31% nonunion rate, although future studies are necessary to substantiate this conclusion. When using a locking plate, additional craniocaudal fixation showed significant better functional outcome.

Low Frequency Electromagnetic Fields Might Increase the Effect of Enamel Matrix Derivative on Periodontal Tissues

Periodontal regeneration is a complex goal, which is commonly pursued with a combination of surgical techniques, biomaterials, and bioactive compounds. One such compound is enamel matrix derivative (EMD), a medical substance that is extracted from porcine tooth germs and which contains several protein fractions with BMP- and TGF-β-like action. Activation of TGF-β signaling is required for EMD activity on cells and tissues, and a growing body of evidence indicates that EMD largely relies on this pathway. As low frequency electromagnetic fields (EMFs) have long been investigated as a tool to promote bone formation and osteoblast activity, and because recent studies have reported that the effects of EMFs on cells require primary cilia, by modulating the presence of membrane-bound receptors (e.g., for BMP) or signal mediators, it can be hypothesized that the application of EMFs may increase cell sensitivity to EMD: as TGFBR receptors have also been identified on primary cilia, EMFs could make cells more responsive to EMD by inducing the display of a higher number of receptors on the cellular membrane.

Efficacy of Using Perichondrioadipodermal Flap With Combined Techniques in Prominent Ear Correction.

Prominent ear is 1 of the most common congenital deformities of the ear. Incidence is reported as approximately 5%. This deformity can classically be the result of antihelix insufficiency, overprojection of concha or combination of both. Less frequently, folded or overprojectile ear lobule can aggravate the deformity. Surgical techniques can be aimed at concha, antihelix formation, lobule positioning. In our study, postoperative results for the combination of suture otoplasty and perichondrioadipodermal flap techniques in prominent ear surgery is discussed in light of the recent literature. Forty-nine patients that were operated for prominent ear deformity in our clinic between 2010 and 2015 were evaluated. Anatomic structures that cause the anomaly was analyzed by photographing concha-scaphoid angle, antithetical fold absence or presence, position of the ear lobule, conchal depth, size of the auricula, and positioning Frankfort Plane parallel to the ground. The patients were photographed preoperatively, at postoperative first week and postoperative sixth month, respectively. Comparison of age, surgical technique, surgical complications, necessity for revision surgery, additional procedures, follow up time, preoperative, and postoperative helix-mastoid bone distance were evaluated. Forty-nine patients have been evaluated. Thirty-one of these patients were female, whereas 18 were male. Age of these patients ranged between 6 and 37. Operations were performed in 47 right side ears, and 44 left side ears (97% bilateral and 7% unilateral otoplasty). Preoperative helix-mastoid bone distance ranged between 21 and 33 mm (mean 26.77), whereas postoperative helix-mastoid bone distance was measured between 12 and 22 mm (mean 16.26). Compared to the preoperative values, helix-mastoid distance difference was statistically significant (P < 0.05). Asymmetry and recurrence are the most common late complications of prominent ear surgeries. Perichondrioadipodermal flap can be safely added to the combined surgical techniques protecting the cartilage support, therefore, reducing complication rates, with satisfying results.

Efficacy and safety of phacoemulsification plus goniosynechialysis and trabectome in patients with primary angle-closure glaucoma

We evaluated the efficacy and safety of combined phacoemulsification, intraocular lens implantation, goniosynechialysis (GSL), and trabectome in patients with primary angle-closure glaucoma (PACG). Twenty patients (22 eyes) of PACG treated with combined phacoemulsification, intraocular lens implantation, GSL, and trabectome between September 2017 and September 2020 were included in this case series study. The intraocular pressure (IOP), number of glaucoma medications, and best-corrected visual acuity (BCVA) were recorded at baseline, 1, 3, 6, and 12 months after surgery. Successful surgery was defined as IOP < 21 mmHg with or without IOP-lowering medications. IOP was decreased significantly from 22.07 ± 6.62 mmHg at baseline to 15.06 ± 3.39 mmHg at 12 months’ follow-up (p = 0.001). The number of glaucoma medications was significantly reduced from 2.68 ± 1.17 preoperatively to 0.78 ± 0.73 at 12 months’ follow-up (p < 0.01). The rate of successful surgery was 88.9% at 12 months. The reduction in IOP showed a positive correlation with baseline IOP (p < 0.001), and the reduction in number of glaucoma medications was positively correlated with baseline number of glaucoma medications (p < 0.001). There were no vision-threatening complications intraoperatively or postoperatively. Combined phacoemulsification, IOL implantation, GSL, and trabectome were effective and safe in PACG patients in this study. These combined surgical techniques may be useful in PACG patients, especially those with long term and extensive peripheral anterior synechiae.

Outcomes of Modified Scarf Osteotomy for Male Hallux Valgus

Category:BunionIntroduction/Purpose:Compared to women, hallux valgus in men is less common, more severe, and has higher rates of undercorrection, recurrence and greater distal metatarsal articular angle (DMAA). Bunionectomies that correct metatarsus primus varus (MPV) by valgus rotation paradoxically increase 1stMTP valgus in high DMAA, contributing to recurrence and undercorrection. While proximal valgus osteotomy or arthrodesis plus distal varus-producing metatarsal osteotomy can correct both components, there is a simpler solution. A modified Scarf osteotomy technique was developed in which the osteotomy is simultaneously translated laterally to correct MPV, while rotating the distal metatarsal in varus to correct DMAA. While previous literature on male hallux valgus is comprised of many studies using a combination of surgical techniques, all patients in this series had the same procedure.Methods:A retrospective review of prospectively collected data was performed in male patients treated with modified scarf osteotomy and soft tissue realignment for symptomatic hallux valgus, who failed conservative treatment. Preop and postop range of motion (ROM), radiographs, and validated patient reported outcome (PROM) scores including Pain VAS and SF-36, were tabulated, as well as complications, and AOFAS Hallux scores for historical comparison. There were 22 patients (26 feet), mean age 53 (17-79). Mean clinical and radiographic follow up was 24 months, and mean postop PROM’s follow up was 4.7 years. Six of 26 feet (23%) required a modified Akin osteotomy for a congruent 1stMTP joint. A subset of patients with minimum 4-year and mean 7.6 -year follow up (9 patients, 10 feet), was also analyzed. Weightbearing radiographs were evaluated for DMAA, hallux valgus angle (HVA) and 1st-2ndintermetatarsal angles (IMA).Results:Statistically significant improvements were found in VAS scores (5.8 to 1, p<0.001); SF-36 physical (44 to 56.7, p<0.001); IMA (15.9 to 8.7, p<0.001), HVA (36.1 to 15.1, p<0.001), DMAA (12.7 to 6.9, p=0.01) and AOFAS scores (44 to 79, p<0.001). Total 1stMTP ROM decreased from 60.9 to 50.8 degrees (p=0.06). One patient had delayed wound healing requiring oral antibiotics and wound vacuum application. Statistically significant improvements were maintained over time in the 7.6-year follow up sub-group, with VAS scores 6.2 to 1.3 (p<0.001), SF-36 physical from 40.8 to 61.3 (p=0.008), and SF-36 mental from 55.7 to 62.3 (p=0.002).Conclusion:This study found statistically significant improvements in both subjective validated PROM’s and objective radiographic measures using a special modification of the scarf osteotomy to address the characteristic increased DMAA that underlies complications and under correction previously reported in male hallux valgus. The corrections were well maintained at long-term follow-up including a robust correction of the DMAA.

Novel Minimal Access Bone Anchored Hearing Implant Surgery and a New Surface Modified Titanium Implant, the Birmingham Experience.

Bone anchored hearing implants (BAHI) are widely used and highly successful, accompanied with a high level of patient satisfaction across most techniques. A large UK teaching hospital switched from the previously used wide diameter titanium fixture and drilling system to the novel minimally invasive technique and laser ablated titanium implant. Before this change the rates of fixture failure and skin problems necessitating abutment change were 1% each. Retrospective case note review of consecutive BAHI patients drawn from an electronic database between January 2015 and October 2016. Data from a total of 118 procedures were reviewed, with different combinations of surgical techniques and implant types. Sixty procedures were performed via the novel minimally invasive technique with 21 failures (35%). Fourty-eight modified minimally invasive technique procedures were performed with seven failures. In 64 of the procedures, laser ablated titanium fixtures were placed with 21 failures (32.8%). In 54 procedures wide diameter titanium fixtures were placed with eight failures (5%). Initial experience with the novel minimally invasive technique and laser ablated titanium fixture showed significantly higher failure rates than expected. This prompted a change to an open technique and subsequent abandonment of the laser ablated titanium fixture and custom drilling solution in our institution.

A Web-Based Survey of Oculoplastic Surgeons Regarding the Management of Lower Lid Retraction

ABSTRACTPurpose: To survey the opinion of oculoplastic surgeons on the assessment and management of lower eyelid retraction (LLR).Methods: A web-based survey queried oculoplastic surgeon members of Ojoplast, Spanish and Brazilian Oculoplastic Societies on the management of LLR. The frequency and percentage proportions of the responses were analyzed.Results: One hundred ninety-six oculoplastic surgeons participated in the survey. The main cause of LLR is post-blepharoplasty (62;31.6%). The most used sign to detect LLR is scleral show. The most common approaches to managing LLR are lateral canthal surgery (164/593;27.6%), autogenous spacers (148/593; 24.9%) and retractor release (131/593;22.1%). The preferred autogenous graft material includes ear cartilage (102/260;39.2%). The majority of surgeons (161/314; 51.3%) recommend massage or steroids injection (80/314;25.5%) for early post-blepharoplasty LLR, while, 54.1% (106/196) of participants suggested waiting for at least six months prior to surgical intervention. Frost suture is used after most LLR surgeries (154/196;91.1%). Incomplete correction is the main complication (111/310;35.8%) of LLR surgery. For mild LLR, 48% of the responders prefer clinical treatment; conversely, severe cases routinely require combined surgical techniques.Conclusions: Oculoplastic surgeons frequently diagnose LLR based on scleral show. LLR management depends on the cause and severity of lid retraction. Mild cases, in general, receive clinical treatment and severe cases need a combination of surgical techniques and grafts.

OPTIONS FOR SURGICAL TREATMENT OF CHRONIC C2 ODONTOID FRACTURES

The paper presents a review of three clinical cases of treating patients with chronic fractures of the odontoid process of C2 vertebra using various combinations of surgical techniques. In all cases, complete decompression of the spinal cord and stabilization of the upper cervical segment of the spine were achieved. A decrease in the range of motion in the cervical spine was observed, which did not affect patient satisfaction. A gradual regression of the neurological status and increase in muscle strength were recorded. Comparative analysis of the neurological status was carried out before and after surgical treatment. When assessing the general condition of patients using the index of disability due to pain in the neck (NDI), an improvement in the quality of life was noted. These data show the opportunities and peculiarities of methods for treating patients with chronic C2 odontoid fractures.Type of publication: description of clinical cases. Evidence level: IV.

Surgical management of hypospadias in cases with concomitant disorders of sex development.

To review the surgical treatment of hypospadias (HP) associated with disorders of sex development (DSD). HP cases were assessed for DSD by gross examination for atypical external genitalia, and assessment of hormone levels and karyotype. There were 58 HP cases with concomitant DSD treated between 1999 and 2017. DSD classification, type of HP, sex assignment, hormonal abnormality, surgical strategy, and post-urethroplasty complications (post-UPC) were reviewed. DSD were sex chromosome abnormalities (n = 4), 46,XY (n = 51), 46,XX (n = 1), and 47,XY + 21 (n = 2). HP was perineal: (n = 26), scrotal: (n = 16), penoscrotal: (n = 15), and midshaft: (n = 1); repair was primary (n = 6) or staged (n = 52). Mean age at final urethroplasty (UP) was 4.12 ± 0.21 years; all cases had soft tissue interposition at UP. At mean follow-up 5.16 ± 0.56years after final UP, observed post-UPC (n = 8; 13.8%) were urethral stenosis (n = 3), urethral diverticulum (n = 2), urethrocutaneous fistula (n = 2), and curvature (n = 1). Mean onset of post-UPC was 1.24 ± 0.77years (range 0.1-6.3). The second half of our cases (n = 29; treated 2015 ~) had significantly less post-UPC (0/29; 0%) than the first half (8/29; 27.6%) (p = 0.0075). Although UP for HP + DSD was formidably challenging, we achieved a significant decrease in post-UPC through a combination of surgical techniques and experience.

MODERN ALGORITHMS OF THORACIC CAGE STABILIZATION IN PATIENTS WITH MULTIPLE RIB FRACTURES AND FLAIL CHEST

Objectives - to improve the treatment results in patients with multiple rib fractures and flail chest via the development and implementation of modern therapeutic and tactical algorithms. Material and methods. A non-randomized prospective study has been carried out to evaluate the results of treatment in 198 patients with multiple rib fractures and flail chest in the period of 2011-2017. Three clinical types were identified: 1) patients with multiple rib fractures with disordered thoracic cage structure - 77 (38.9%); 2) patients with flail chest - 71 (35.9%); 3) patients with multiple rib fractures without disordered thoracic cage structure - 50 (25.2%). There were developed and applied the diagnostic and treatment algorithms depending on the severity of injures of sternocostal frame and intrapleural organs, the presence and severity of associated injuries and background diseases, the conditions of medical aid. Results. The treatment tactics of all patients was based on the differentiated, staged and combined use of various methods of stabilizing the thoracic cage including the advanced types of medical care. Surgical stabilization methods were used in 162 patients, in 26 of them a combination of surgical techniques was applied, in 20 - the internal pneumatic stabilization, in 42 - the conservative treatment was performed. The retrospective analysis and the obtained results compared to the results of the equivalent historical group allowed us to state the decrease of mechanical ventilation time from 11.0 ± 3.9 to 5.1 ± 3.2 days (t = 1.17; p&gt; 0.05), the length of stay in the ICU from 11.5 ± 5.4 to 6.8 ± 3.7 days (t = 0.72; p&gt; 0.05), the complications frequency from 36.5% to 15.9% and mortality rate from 22.3% to 8.7%. Conclusion. Modern diagnostic and treatment algorithms in patients with multiple rib fractures and flail chest are based on stage-by-stage application, succession and combination of various methods of the thoracic cage stabilization throughout the medical assistance process. The algorithms, allowing to stabilize the thorax and to improve the condition of the patients in general, make it possible to realize the full potential of modern thoracic surgery.
