The thumb and first webspace are involved in a relatively low proportion of cases of Dupuytren disease of the hand (3%-28%). Given the rarity, there has been a paucity of literature regarding anatomic cord configurations and the surgical technique for the management of such radial-sided diseases. There are unique anatomic considerations in the thumb that warrant understanding prior to safe surgical exploration. A case of an anatomic variant of Dupuytren disease involving the thumb and first webspace treated with a webspace skin-sparing partial fasciectomy is described. The current literature regarding surgical management of Dupuytren disease affecting the thumb and first webspace is also briefly presented.

BACKGROUND/UNASSIGNED:Despite evidence documenting the physical and psychological benefits of breast reduction, third-party payer approval remains a cumbersome process. The objective of this study was to assess differences in medical necessity criteria for reduction mammaplasty among US insurance carriers while analyzing trends in claim denials and appeals. METHODS/UNASSIGNED:The medical necessity criteria for reduction mammaplasty were retrieved from seven large health insurance carriers. Data were extracted from each policy, including claim requirements for approval. Additionally, prospective data on claims and denials submitted from January through August 2022 were collected from The Auctus Group, a medical consulting firm. RESULTS/UNASSIGNED:All the policies have been updated since January 2020. Five of the seven policies specifically listed what documentation was required for preauthorization approval, with five third-party payers requiring photograph documentation. Policies required documentation of one to three symptoms lasting from 6 weeks to 1 year. All companies reported a tissue resection estimate threshold, but cutoffs varied. Of 380 reduction mammaplasties performed, 158 (41.6%) received a denial on initial insurance submission. Considering appeals, a total of 216 denials were reviewed with an average of 1.37 denials per patient. Of the 158 initial denials, 104 (65.8%) of these were from claims that received preauthorization. In 12 cases, third-party payers stated that no prior authorization was necessary yet still denied the claim. CONCLUSIONS/UNASSIGNED:Wide variability exists in medical necessity criteria for reduction mammaplasty policies among major insurance carriers. These nuances introduce inefficiencies for practices contributing to high denial and appeal rates while delaying surgical care for patients.

BACKGROUND/UNASSIGNED:In October 2012, an open-access, multimedia digital cleft simulator was released. Its purpose was to address global disparities in cleft surgery education, providing an easily accessible surgical atlas for trainees globally. The simulator platform includes a three-dimensional surgical simulation of cleft care procedures, intraoperative videos, and voiceover. This report aims to assess the simulator's demographics and usage in its tenth year since inception. Finally, we also aim to understand the traction of virtual reality in cleft surgical education. METHODS/UNASSIGNED:Usage data of the simulator over 10 years were retrospectively collected and analyzed. Data parameters included the number of users, sessions, countries reached, and content access. An electronic survey was emailed to registered users to assess the benefits of the simulator. RESULTS/UNASSIGNED:The total number of new and active simulator users reached 7687 and 12,042. The simulator was accessed an average of 172.9.0 ± 197.5 times per month. Low- to middle-income regions accounted for 43% of these sessions. The mean session duration was 11.4 ± 6.3 minutes, yielding a total screen time of 3022 hours. A total of 331 individuals responded to the survey, of whom 80.8% found the simulator to be very useful or extremely useful. Of those involved in education, 45.0% implemented the simulator as a teaching tool. CONCLUSIONS/UNASSIGNED:Global utilization of the simulator has been sustained after 10 years from inception with an increased presence in low- to middle-income nations. Future similar surgical simulators may provide sustainable training platforms to surgeons in low- and high-resource areas.

A 3-year-old patient sustained a tripartite mandibular fracture, including bilateral condylar fractures with lateral dislocation of the left condyle and symphyseal fracture. Staged lower jaw reconstruction with closed reduction of the laterally dislocated condyle, transfacial pinning between the mandibular angles, MMF using circummandibular wiring and intermaxillary fixation screws was performed.

BACKGROUND:Reduction mammaplasty pathologic specimens can reveal incidentally found proliferative lesions. However, there is a lack of data investigating the comparative incidences and risk factors for such lesions. METHODS:A retrospective review was conducted of all consecutively performed reduction mammaplasty cases at a single large academic medical institution in a metropolitan city by two plastic surgeons over a 2-year period. All reduction mammaplasties, symmetrizing reductions, and oncoplastic reductions performed were included. There were no exclusion criteria. RESULTS:A total of 632 breasts were analyzed-502 reduction mammaplasties, 85 symmetrizing reductions, and 45 oncoplastic reductions-in 342 patients. Mean age was 43.9 ± 15.9 years, mean body mass index was 29.2 ± 5.7 kg/m 2 , and mean reduction weight was 610.0 ± 313.1 g. Patients who underwent reduction mammaplasty for benign macromastia had a significantly lower incidence (3.6%) of incidentally found breast cancers and proliferative lesions compared with patients with oncoplastic reductions (13.3%) and symmetrizing reductions (17.6%) ( P < 0.001). On univariate analysis, personal history of breast cancer ( P < 0.001), first-degree family history of breast cancer ( P = 0.008), age ( P < 0.001), and tobacco use ( P = 0.033) were all statistically significant risk factors. Using a backward elimination stepwise reduced multivariable logistic regression model for risk factors associated with breast cancer or proliferative lesions, age ( P < 0.001) was the only retained significant risk factor. CONCLUSIONS:Proliferative lesions and carcinomas of the breast found in reduction mammaplasty pathologic specimens may be more common than previously reported. The incidence of newly found proliferative lesions was significantly lower in cases of benign macromastia compared with oncoplastic and symmetrizing reductions. CLINICAL QUESTION/LEVEL OF EVIDENCE:Risk, II.

BACKGROUND:Mastectomy flap necrosis (MFN) is a common complication of immediate breast reconstruction that greatly affects patient satisfaction and cosmetic outcomes. Topical nitroglycerin ointment, with its low cost and negligible side effects, has been shown to significantly decrease the incidence of MFN in immediate implant-based breast reconstruction, but its utility has not been studied in immediate autologous reconstruction. METHODS:With institutional review board approval, a prospective cohort study was performed of all consecutive patients undergoing immediate free-flap breast reconstruction by a single reconstructive surgeon at a single institution between February of 2017 and September of 2021. Patients were divided into two cohorts: those who received 30 mg of topical nitroglycerin ointment to each breast at the conclusion of the operation (September of 2019 to September of 2021) and those who did not (February of 2017 to August of 2019). All patients underwent intraoperative SPY angiography, and mastectomy skin flaps were débrided intraoperatively based on imaging. Independent demographic variables were analyzed, and dependent outcome variables included mastectomy skin flap necrosis, headache, and hypotension requiring removal of ointment. RESULTS:A total of 35 patients (49 breasts) were included in the nitroglycerin cohort and 34 patients (49 breasts) were included in the control group. There was no significant difference in patient demographics, medical comorbidities, or mastectomy weight between cohorts. The rate of MFN decreased from 51% in the control group to 26.5% in the group that received nitroglycerin ointment ( P = 0.013). There were no documented adverse events associated with nitroglycerin use. CONCLUSION:Topical nitroglycerin ointment significantly decreases the rate of MFN in patients undergoing immediate autologous breast reconstruction without significant adverse effects. CLINICAL QUESTION/LEVEL OF EVIDENCE:Therapeutic, II.

Genital surgery for the treatment of gender dysphoria has undergone significant evolution since its inception in the first half of the 20th century. Robotic approaches to the pelvis allow for improved visualization and reduced abdominal wall morbidity, making the robotic surgical system a very useful tool in the gender affirming genital surgeon's armamentarium. In penile inversion vaginoplasty, robotically harvested peritoneal flaps can be used to augment the vaginal canal, thereby leading to improved vaginal depth, as well as improve operative efficiency by facilitating a two-surgeon approach. In transgender men, the robotic approach to vaginectomy assists with visualization to confirm complete obliteration of the vaginal canal. Robotic surgery will play a central role in the continued evolution of the field of gender affirming surgery.
