Trends in Anterior Cruciate Ligament Reconstruction Techniques and Postoperative Care Among Leaders in the Field: A Survey of the Herodicus Society.

Despite a growing body of literature regarding anterior cruciate ligament reconstruction (ACLR), there remains a wide diversity in surgical technique and clinical practice across providers. To (1) describe current ACLR practice preferences among members of the Herodicus society and (2) determine whether these preferences are influenced by years in practice and overall surgical volume. Cross-sectional study. A 24-question survey investigating surgeons' practices and preferred ACLR surgical techniques was sent via email to all active Herodicus Society members. Survey responses were subdivided by years of experience and overall ACLR annual case volume. Descriptive statistics were compiled and chi-square testing was utilized to determine the significance of experience and case volume on survey responses. Of the 113 invited Herodicus Society members who perform ACLR, 69 (61%) completed the survey. Respondents had a mean ± SD of 30.9 ± 9.8 years of experience in clinical practice and performed a mean of 96.0 ± 50.7 primary and 21.6 ± 16.9 revision ACLR annually. Of revision cases, 72.1% were performed using a single-stage technique. Mean frequency of graft usage by surgeon was bone-patellar tendon-bone autograft (58.6%), quadriceps autograft (14.6%), hamstring tendon autograft (14.0%), and allograft (11.8%). The plurality of surgeons responded that they used anterolateral augmentation "rarely" in primary ACLR (39.1%) and "sometimes" in revision ACLR (31.9%), with the majority performing lateral extra-articular tenodesis (66.7%) rather than anterolateral ligament reconstruction (14.5%). Most surgeons would not allow a 20-year-old football player to return before 7 months after ACLR (71.0%) but highly valued return-to-sports testing to determine readiness (94.2%). Higher volume surgeons performed single-stage revision ACLR at a significantly higher rate (79.8% vs 62.9%, P = .02) and significantly differed in return-to-sports criteria, with a greater proportion relying primarily on biometric testing (P = .01). The survey demonstrated that, in the Herodicus Society, a wide range of preferences exist regarding ACLR surgical technique. Bone-patellar tendon-bone autograft is the most frequent primary ACLR graft choice. Most participants have not embraced newer techniques such as anterolateral or suture tape augmentation. Return to sports is generally not allowed before 7 months and heavily factors-in return-to-sports testing metrics, suggesting that purely time-based criteria for return to sports is not modern practice among elite sports medicine surgeons.

What Is the Carbon Footprint of Adult Spinal Deformity Surgery?

Background/Objectives: While the economic cost of adult spinal deformity (ASD) surgery has been studied extensively, its environmental impact is unknown. The aim of this study is to determine the carbon footprint (CF) associated with ASD surgery. Methods: ASD patients who underwent > four levels of corrective surgery between 2017 and 2021 were included. The open group included a posterior-only, single-stage technique, while the minimally invasive surgery (MIS) group was defined as the use of lateral interbody fusion and percutaneous posterior screw fixation. The two groups were propensity-score matched to adjust for baseline demographic, surgical, and radiographic characteristics. Data on all disposables and reusable instruments, anesthetic gas, and non-gas medications used during surgery were collected from medical records. The CF of transporting, using, and disposing of each product and the footprint of energy use in operating rooms were calculated. The CF produced was evaluated using the carbon dioxide equivalent (CO2e), which is relative to the amount of CO2 with an equivalent global warming potential. Results: Of the 175 eligible patients, 15 pairs (65 ± 9 years, 47% female) were properly matched and analyzed for all variables. The average CF generated per case was 147.7 ± 37.3 kg-CO2e, of which 54% was attributable to energy used to sterilize reusable instruments, followed by anesthetic gas released into the environment (17%) and operating room air conditioning (15%). Conclusions: The CF generated during ASD surgery should be reduced using a multidisciplinary approach, taking into account that different surgical procedures have different impacts on carbon emission sources.

One-Stage Deep Inferior Epigastric Perforator Flap Salvage of Infected Tissue Expanders

Background Tissue expander-based breast reconstruction is associated with high rates of infectious complications, often leading to tissue expander explants and delays in receipt of definitive breast reconstruction and adjuvant therapy. In this study, we describe a single-stage technique where deep inferior epigastric artery perforator (DIEP) flaps are used to salvage actively infected tissue expanders among patients originally planning for free flap reconstruction. Methods In this technique, patients with tissue expander infections without systemic illness are maintained on oral antibiotics until the day of their DIEP flap surgery, at which time tissue expander explant is performed in conjunction with aggressive attempt at total capsulectomy and immediate DIEP flap reconstruction. Patients are maintained on 1–2 weeks of oral antibiotics tailored to culture data. Patients undergoing this immediate salvage protocol were retrospectively reviewed, and complications and length of stay were assessed. Results In a retrospective series, a total of six consecutive patients with culture-proven tissue expander infections underwent tissue expander removal and DIEP flap reconstruction in a single stage and were maintained on 7–14 days of oral antibiotics postoperatively. Within this cohort, no surgical site infections, microvascular complications, partial flap losses, reoperations, or returns to the operating room were noted within a 90-day period. Conclusions Among a select cohort of patients, actively infected tissue expanders may be salvaged with free flap breast reconstruction in a single surgery with a low incidence of postoperative complications. Prospective studies are needed to evaluate the influence of this treatment strategy on costs, number of surgeries, and dissatisfaction after staged breast reconstruction complicated by tissue expander infections.

Retrospective Comparative Study between Duplay and Koff Methods in Repair of Distal Hypospadias.

Hypospadias repair is a complicated surgery even in the best of hands. To date, there is a lack of consensus on which surgical technique offers more favourable post-operative outcomes. The present work was undertaken to evaluate and compare the outcomes and complications rates of two single-stage techniques widely used to repair primary anterior hypospadias, namely Thiersch-Duplay Tubularized Plate Urethroplasty and Koff Urethral Mobilisation and Advancement. Data from the medical records of 120 patients operated on for primary anterior hypospadias were retrospectively analysed and compared. The patients were divided into two groups: 60 patients underwent Thiersch-Duplay procedure (Group A) and 60 patients underwent Koff procedure (Group B). They were compared using the Chi-squared or Fisher's exact test to assess the relationship between the adopted surgical technique and the complications' development with a P < 0.05. Neither intraoperative complications nor acute post-operative complications occurred, whereas 28.3% ( n = 34/120) cases have exhibited at least one late post-operative surgical complication, including 38.3% ( n = 23/60) in Group A and 18.3% ( n = 11/60) in Group B, revealing a better outcome of the Koff procedure despite the statistical insignificance ( P = 0.102). We did not objectify any other complication besides meatal stenosis (MS), urethro-cutaneous fistula (UCF) and wound dehiscence. Overall, our study could not demonstrate the superiority of one technique above another. At the same time, it established the versatility, satisfactory cosmetic and functional results, low MS and UCF rates of Koff urethral mobilization and advancement technique in primary anterior hypospadias repair.

An Evaluation of Retention of Complete Denture Bases Made with a “Modified Single-stage Impression” Technique Using a Heat-moldable Tray

Abstract Aim: Although most dental schools teach complete denture definitive impression techniques consisting of secondary impressions in border-molded custom impression trays, it has been found that later, graduates in clinical practice abandon this step because of its complexity and attempts to seek easier alternatives. To simplify two-stage techniques, single-step border molding with elastomeric impression materials and light-cured resin materials has gathered acceptance among clinicians. The study aims to evaluate the retention of record bases made with a modified single-stage impression technique that uses elastomeric impression material in a heat moldable tray with modeling compound as material for border molding. Settings and Design: This was an in vivo preliminary cohort study. Materials and Methods: Thirteen completely edentulous patients requiring complete dentures were included in the study. A traditional two-stage impression was made using custom trays fabricated over diagnostic casts and further border molding done with a modeling compound, and the final impression was made to use zinc oxide–eugenol impression material. Additionally, a modified single-stage impression technique using heat moldable impression trays was made. Master casts from each technique were made, and further record bases were made on each master cast. Wire loops were adapted on the palatal aspect of record bases. The retention of each record base was evaluated using a force gauge. Statistical Analysis: The Kolmogorov–Smirnov test was used to analyze the normality of variables and later Wilcoxon signed-rank test was applied. Results: The double-stage technique exhibited retention values in the range of 0.6–66.7 units, whereas the single-stage technique showed a range of 0.15–78.55. The tests showed no significant difference between double-stage and single-stage techniques (P &gt; 0.05). Conclusions: The single-stage technique using heat moldable trays with elastomeric impression material and modeling compound as a material for border molding can produce denture retention compared to the conventional technique that uses a two-step impression technique. The use of the modified single-stage technique can additionally save an extra appointment for patients, although it is better to use such a technique as an advanced impression technique and not as a training technique for beginners or students, as the material cost is substantially higher than the conventional two-stage technique.

Autogenous Dental Transplantation: Case Series

Autogenous dental transplantation is defined as the transfer of a tooth to a recipient site of the same individual, whether it is a recently extracted site or surgically prepared bed. This procedure has proven to be a good and cost-effective alternative for replacing teeth with indications for extraction. Depending on the case, it is possible to maintain the vitality of the tooth and the periodontal ligament, ensuring proprioception and physiological dental mobility. The aim of the study is to describe a series of clinical case reports of autogenous dental transplants, in addition to discussing the results obtained based on current literature. The study features with a series of autogenous dental transplant cases conducted at Euro American University Center, where the indication for such a procedure was the extensive coronal destruction of the first molars in young patients. The surgeries were performed in atraumatic manner using a single-stage technique and semi-rigid splinting with occlusive sutures using 4-0 nylon thread. The results demonstrate significant success in the postoperative period, with the absence of symptoms and maintenance of pulp vitality and periodontal ligament. Based on the studies and case reports, it was observed that transplantation remains a safe and economically viable alternative for the replacement of prematurely lost teeth, within its indications and limitations.

Systematic Review of Clinical Outcomes After Proximal Tibia Anterior Closing-Wedge Osteotomy With ACL Reconstruction.

While increased posterior tibial slope (PTS) is an important risk factor for failure after anterior cruciate ligament (ACL) reconstruction, controversy exists regarding indications and outcomes of proximal tibia anterior closing-wedge osteotomy (ACWO) with concomitant ACL reconstruction in patients with ACL tears. To assess clinical outcomes after combined ACL reconstruction and proximal tibia ACWO. Systematic review; Level of evidence, 4. In accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines, we performed a systematic review of the existing literature on ACWO and ACL reconstruction using PubMed (MEDLINE), Cochrane Library, Scopus, and Embase. The search phrases included "anterior closing wedge osteotomy,""anterior closing wedge tibial osteotomy,""anterior closing wedge proximal tibial osteotomy,""anterior cruciate ligament," and "revision anterior cruciate ligament." Non-English publications and single-patient case reports were excluded. Extracted data included study details, patient demographics, patient-reported outcomes (PROs), clinical outcomes, radiographic outcomes, complications, and return-to-sport (RTS) rates. A total of 6 studies with 110 patients (110 knees) were included. Two-stage ACWO and ACL reconstruction was reported in 2 studies of 78 patients (71%), while a single-stage technique was reported in 4 studies of 32 patients (29%). ACWO was performed in the setting of primary ACL tear in 23 patients (21%) and in recurrent ACL tear in 87 patients (79%). Patients demonstrated postoperative improvements in Lysholm, pivot-shift test, and side-to-side difference in anterior tibial translation. After ACWO, all studies reported mean postoperative PTS of <10° (range, 4.4°-9.2°). Of patients with available RTS data (n = 43), the same-level RTS rate ranged from 65% to 100%. A two-stage procedure reported in 1 study had a lower RTS rate (n = 13 of 20 [65%]) than that of 2 studies with single-stage procedure (n = 4 of 5 [80%] and n = 18 of 18 [100%]). The overall complication rate was 0.9% to 1.3%, and there were no reported ACL retears. The current evidence, which is constrained by the quantity and quality of studies, showed that ACWO with single- or two-stage ACL reconstruction in patients with ACL insufficiency and increased PTS was associated with significant improvements in PROs and high RTS rates.

Powder mixed electrical discharge machining: One step method to create functional surfaces

The present work proposes a novel single stage technique to establish functional surfaces on machined component through powder mixed EDM process. A comparative analysis on surfaces generated by MoS2 powders of two distinct sizes Ф 40 µm (µP) and 90 nm (nP) mixed into dielectric of EDM is explored. Current (Ip) is chosen as input parameter and its consequence on Rq, Rsk, Rku, recast layer thickness (RCLT) and EDS analysis of AISI 304 machined surface is assessed. The Rq grows in proportion to rise in Ip magnitudes for both µP and nP mixed dielectric. At smaller magnitudes of Ip, a unique combination of negatively skewed and positive kurtosis surfaces are generated in both µP and nP mixed dielectric. The RCLT grows with increasing Ip magnitudes and the deposition of MoS2 on machined surface is perceived through EDS profiles.

Seismic random noise attenuation via a two-stage U-net with supervised attention

Random noise, which has a significant impact on subsequent processing and interpretation, easily interferes with seismic data. Current convolutional neural networks (CNN) use a single-stage technique to boost network capacity by exploiting the complicated network structure, but the performance of the network becomes saturated and prone to overfitting at a certain stage. Hence, we propose a two-stage U-Net denoising network with a supervised attention module (UNet-SAM). In this supervised algorithm, the first stage obtains the pre-denoising results, while the second stage achieves more accurate data. The supervised attention module (SAM) block is inserted in the first stage, extracting features with supervised attention to utilise as a priori information and guide the fine denoising in the second stage. The combination of the attention mechanism and two-stage strategy provides prior information that helps to train a network with better denoising performance. Experiments on synthetic and field data illustrate that the proposed UNet-SAM not only has a superior denoising effect but also retains more of the original effective signal.

The Arch-First Technique for Complex Arch and Proximal Descending Aortic Aneurysms

Aneurysms involving both the aortic arch and proximal descending aorta present a unique surgical challenge due to their anatomical location, with neither standard sternotomy nor thoracotomy alone providing adequate exposure to complete a full repair. Conventional and frozen elephant trunk procedures have inherent problems, including high cumulative mortality and high spinal cord ischaemia rates, which may be obviated using a single-stage technique via bilateral thoracotomies or extended median sternotomy with left anterior thoracotomy.

Single-Stage Posterior Vomerine Ostectomy and Primary Cheiloplasty in Patients with Bilateral Cleft Lip & Palate and Protuberant Premaxilla.

A protruded premaxilla has always been challenging to care for by cleft care professionals. This study aims to fortify the use of a single-stage premaxillary setback, with posterior vomerine ostectomy and primary cheiloplasty to achieve proper care for patients with bilateral cleft lip and palate (BCLP) and protruded premaxilla. Longitudinal retrospective analysis. Twenty-three outreach programs to four countries (Ecuador, Lebanon, Peru, and El-Salvador) between 2016-2022. Sixty-five patients between the ages of 3 months and 6 years and 5 months, with BCLP and severely protruded premaxilla underwent premaxillary setback via posterior vomerine ostectomy and primary cheiloplasty. Patients with diagnosed syndromes and inaccessible vomer bone due to fused palates were excluded from the study. Premaxillary setback with posterior vomerine ostectomy, bilateral gingivoperiosteoplasties (GPP), and primary cheiloplasty. Postoperative complications and aesthetic outcomes. The mean age at surgery was 13.17 ± 14.1 months, with an average follow-up time of 26 ± 17 months. Patients underwent their procedures in Ecuador (72%), Peru (9%), Lebanon (8%) and El-Salvador (1%). The majority of patients were aged 1 year or less (66.7%) and were males (58.5%). All patients were operated on successfully and had good aesthetic outcomes. Only one patient developed partial necrosis. Patients with BCLP and severe premaxillary protrusion have always carried immense social, psychological, and financial burdens, especially in outreach settings. Our described single-stage technique has proven to be safe and effective with good aesthetic results. Further follow-up after primary repair should be done to document and ensure proper facial growth and normal nasolabial maturation.

P3 Flap: Technique for Fingertip Reconstruction

Summary: Fingertip amputations represent an important spectrum of injuries, and most are avulsions or crush trauma. There is no consensus about one single standard treatment, and a wide number of techniques are available. The authors present the P3 flap as an option for covering fingertip defects with bone exposure, avoiding painful scars in the pulp area, without a donor site. This study included 12 fingertips with amputated segment not available for replantation. Volar oblique fingertip defects and transverse amputations with bone exposure, not more proximal than Hirase Zone IIB, were included. Defects were less than 2 cm. The patients were followed up for an average of 6 months. The aesthetic and functional outcomes and fingertip discrimination recovery were evaluated at 6 months by the static two-point discrimination (2-PD) test and DASH score (quick version). The average postoperative 2-PD test at 6 months was 5.9 mm (range from 5 to 8 mm). The mean healing time of the fingertip was 4 weeks. Nail deformity was reported in three cases with level IIB of amputation. None of the P3 flaps failed, and local infection was not reported. The average DASH score at 6 months was 1.1. The mean time to return to work was 38 days (range from 30 to 53). The P3 flap proposed in this study demonstrates a reliable single-stage technique, performed under local anesthesia, for fingertip defect reconstruction, avoiding skin incision and scars in the pulp region and preserving digital length and nail bed.

At the heart of the debate lies the issue of whether or not a single-stage reconstruction should be employed over a 2-stage repair to minimize the number of surgeries performed. Additionally, depending on patient preference, a urethrostomy is a viable option. The objective of this study is to compare single-stage urethroplasty, staged urethroplasty and perineal urethrostomy for the treatment of LS related penile urethral strictures in a multi-institutional analysis. METHODS: A retrospective analysis was performed on patients undergoing urethroplasty for LS induced isolated penile urethral strictures (LSE S2b/S2c) at 9 different institutions. Meatal strictures <2 cm in length and panurethral strictures (>10 cm) involving the bulbar urethra were excluded from study. Patients were reconstructed using either a single-stage approach, a staged technique or perineal urethrostomy. The primary outcome measure was urethral patency at routine follow-up cystoscopy without stricture intervention thereafter and secondary outcomes were 90-day complications, and adverse change in sexual dysfunction, chordee or urethrocutaneous fistula. Outcomes were compared using a Cox regression or a two-tailed Chi-square test when appropriate. RESULTS: 231 patients were analyzed with an average age of 51.6 years and mean stricture length of 5.5 cm. Prior endoscopic treatments were performed in 197 patients (85.3%) with a mean of 3.0 prior endoscopic treatment attempts. Overall, 127 (55.0%) were managed with single-stage BMG urethroplasty, 44 (19.0%) with staged BMG, and 60 (26.0%) with perineal urethrostomy. At a mean follow-up of 68.6 months, overall stricture free rate was 81.0% (n=187). Clavien ≥2 90-day complications occurred in 17 patients (9.8%). de novo erectile dysfunction occurred in 13 patients (5.6%), chordee in 7 (4.8%), and urethrocutaneous fistula in 3 (3.4%). On Mantel-Cox testing, there was no difference in stricture recurrence between techniques (15.7% vs. 27.3% vs. 20.0%; p=0.60) and no difference in 90-day complications (8.0% vs. 15.6% vs. 9.8%; p=0.45), erectile dysfunction (7.1% vs. 4.5% vs. 3.3%; p=0.55), chordee (6.7% vs. 0.0% vs. 3.6%; p=0.33), and urethrocutaneous fistula (2.2% vs. 9.1% vs. 0.0%; p=0. 0.17). On Cox regression analysis, obesity (BMI>35) was associated with a higher rate of stricture recurrence (Hazard Ratio 2.31, 95%CI 1.28-4.17, p=0.006, 30.1% vs. 13.9%) but not 90-day complications (Odds Ratio 1.00, 95% CI 0.33-2.99, p=0.99, 9.8% vs. 9.8%). No other clinical variable was associated with stricture recurrence or 90-day complications. CONCLUSIONS: Favorable outcomes of single-stage techniques for the treatment of lichen sclerosus induced penile urethral strictures, confirm single-stage urethroplasty as the treatment standard for LS induced penile urethral strictures especially when considering the decreased number of surgeries the patient is exposed to.

Gender-Specific Evaluation Following McLaughlin’s Dynamic Muscle Support for Irreversible Facial Paralysis

Failure of the mimic muscles as a cause of facial nerve paralysis may result in significant asymmetry, which can be addressed by surgical reanimation procedures. Among those, the temporalis muscle transfer as advocated by McLaughlin is a single-stage technique for the dynamic reanimation of the mouth. Despite increasing research directed at women’s health, the gender-specific differences of this technique have not yet been addressed. Thus, we retrospectively reviewed the medical records of patients who underwent this operation between 2001 and 2021 for gender-specific differences concerning the postoperative outcome. In total, 28 women and 17 men were included. The two cohorts were statistically comparable with respect to etiological characteristics such as age, duration and etiology of paralysis, and preoperative degree of symptoms. After a median follow up of 15 months, restoration of smiling and elevation of the oral commissure was more often achieved among women than men. A statistically significant difference, however, could only be shown for the latter. Resting symmetry was restored in about 50% of both genders. There were no differences concerning postoperative complications or reoperations. The McLaughlin’s dynamic muscle support effectively re-establishes the elevation of the oral commissure and ability to smile among both genders, albeit women tend to be more likely to achieve the desired results.

A Proprietary ZVS-Based Approach Delivers High Efficiencies at Light Load With Half the Components of Conventional Designs

The ac–dc power supply units providing isolated, regulated outputs operating above 100 W typically require some form of input active power factor correction (PFC) <xref ref-type="bibr" rid="ref1" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[1]</xref> . To achieve this, a popular solution is to combine a boost PFC input stage with an “LLC” converter which isolates and controls the dc output voltage. However, a new, innovative single-stage technique for delivering regulated ac–dc power with a high input power factor offers the promise of high efficiency from no-load to full-load, while halving the number of active devices (MOSFETs) when compared to the traditional approach.

The Outcome of Single Stage versus Two Stage Repair in Anorectal Malformations with Recto-Vestibular Fistula

Background: Imperforate anus with recto-vestibular fistula is one of the most common anorectal malformations in females. Wound infection and disruption after recto-vestibular fistula repair may affect the fecal continence and functional outcome. Fecal incontinence may cause long term social, economical and psychological problems in children. Although a protective colostomy reduces the infectious complications and dehiscence, it is also associated with many problems. Aim: To compare the safety, feasibility, post operative complications and functional outcomes of limited posterior sagittal anorectoplasty with or without colostomy. Study design: Prospective descriptive study. Place and duration of sudy: Department of Pediatric Surgery, Sahiwal Teaching Hospital Sahiwal, from 1st January 2019 to 31st December 2021. Methodology: Forty-one patients with congenital recto-vestibular fistula were managed by two techniques. Patients were divided into two groups. Group A (19 patients): were operated by single stage limited posterior sagittal anorectoplasty without covering colostomy. Group B (22 patients): were operated by two stage technique. Limited posterior sagittal anorectoplasty and covering colostomy in first stage and stoma closure was done in second stage. The patients in both groups were evaluated for hospital stay, operation time, postoperative complications, fecal continence, constipation, bowel function. Results: The age of patients ranged from 11-56 months (mean 26.93 months) in Group A and 9-60 months (mean 27.03 months) in Group B. The total length of hospital stay in Group A ranged from 7-11 days (mean 9.20 days); however, in Group B, it ranged from 4-6 days (mean 5.01 days) for first stage procedure and 8-11 days (mean 9.27 days) for second stage colostomy closure procedure. In Group A, complications were, wound infection 03 (15.78%), anal stenosis 02 (10.52%), mucosal prolapse 01 (5.26%), constipation 04 (21.05%), soiling 04 (21.05%), perineal excoriation 03 (15.78%) and recurrent H-type recto-vestibular fistula 01 (5.26%). In Group B, during the first stage of repair, one patient (4.54%) developed wound infection. Mucosal prolapse was observed in one patient (4.54%). Constipation was reported in 03 (13.63%) and soiling in 01 (4.54%). Peri stoma skin excoriation was seen in five patients (22.72%). Stomal prolapse was observed in two patients (9.09%). Two patients (9.09%) developed wound infection after colostomy closure. Conclusion: Single stage repair of congenital recto-vestibular fistula increases the risk of postoperative complications. Two stage approach is associated with less postoperative complications. However it is associated with lengthy hospital stay, long operation time and complications related to stoma formation and closure.

Glabellar superciliary bilobed flap for reconstruction of large medial canthus region defect

The aim of this study was to describe a series of patients who have undergone a medial canthal reconstruction with a glabellar superciliary bilobed flap. A series of 30 patients were included with medial canthal defects after excision of medial canthal tumour who underwent reconstruction using a glabellar-superciliary bilobed flap of adjoining skin and subcutaneous tissue. Eighteen procedures were performed under local anaesthesia. The remaining 12 cases were combined with major lid reconstruction and performed under general anaesthesia. Complete closure of the defect, aesthetic outcome, complications, and re-operations were all used as outcome measures. Primary closure of the donor site was achieved in all cases without wound dehiscence. In all cases, the cosmetic appearance was highly satisfactory to the surgeons and patients and there were no intraoperative complications. The glabellar superciliary bilobed flap is an effective, quick, simple, and single-stage technique for medial canthal region reconstruction. It provides excellent cosmesis and is associated with minimal complications. It can be modified according to the nature of the periorbital skin, location, size, and depth of the defect.

Introduction of a modified single stage reconstruction technique of male penopubic epispadias

ObjectiveTo represent the long-term outcomes of our modified single-stage technique for the reconstruction of isolated penopubic epispadias in male patients.Patients and methodsData from 113 patients were obtained from bladder-exstrophy-epispadias database of our tertiary center. A total of seven boys with isolated penopubic epispadias with no prior history of surgery and any other anomaly underwent our modified surgical approach from February 1997 to September 2019. The mean ± SD age at surgery was 6.5 ± 2.4 years. Volitional voiding status and cosmetic appearance were evaluated at each follow-up interval. Postoperative follow-up was performed at quarterly intervals in the first year and once a year in subsequent years.ResultsThe mean ± SD of follow-up was 8.5 ± 6 years. All boys who were incontinent achieved urinary control and the ability of normal transurethral micturition following the surgery. Four boys became completely dry, and the other three attained social dryness. Postoperative mean (SD) bladder capacity was significantly increased from 54.5 (11) to 124 (40.0) within 6 months, and to 194 (47.5) at 18 months after surgery. Dorsal curvature has been resolved in all cases, and no postoperative complications were noted except for surgical site infection in one patient treated with antibiotics and bilateral vesicourethral reflux resolved after injection of bulking agents. Four patients had normal erectile function and ejaculation, while the others have not reached puberty yet. Moreover, none of the patients developed urethrocutaneous fistula, stricture, or penile ischemia.ConclusionThe present findings suggest the safety and effectiveness of the combination of single-stage urethro-genitoplasty, bladder neck plication, and fat pad pedicled flap in management of boys with isolated penopubic epispadias that can lead to the achievement of urinary control, acceptable sexual function, and cosmetically satisfactory genitalia. Minimal morbidity, low complication rate, and promising outcomes are essential factors, supporting the notion of introducing this technique as a valid option for management of this entity.
