BACKGROUND:The reverse sural artery flap (RSAF) is a popular option for patients with distal lower extremity defects who are not ideal candidates for free flap reconstruction. This is the first systematic review and pooled analysis of surgical characteristics, risk factors, and outcomes of the RSAF. METHODS:A systematic literature review was conducted. All studies reporting on patients undergoing RSAF reconstruction and their outcomes were included. Outcomes were pooled and analyzed using Fisher exact or χ test. RESULTS:Forty-three studies (479 patients, 481 flaps) were analyzed. The majority of patients were male (70.3%), and average ± SD age was 46.9 ± 16.7 years. Rates of smoking, diabetes mellitus (DM), and peripheral vascular disease (PVD) were 34.6%, 35.4%, and 12.3%, respectively. Defect etiologies were largely traumatic (60.4%). The most common defect location was the heel (40.8%). Flap modifications were reported in 123 flaps (25.6%). The most common modification was adipofascial extension (20.3%).Overall, the partial and total flap loss rates were 15.4% and 3.1%, respectively. Partial flap loss was significantly increased in smokers (28.9% vs 12.2% in nonsmokers, P = 0.0195). Technical modifications decreased the odds of partial necrosis by almost 3-fold compared with traditional RSAF reconstruction (7.2% vs 17.9%; odds ratio, 2.8 [1.4-5.8]; P = 0.0035). Patient age, DM, and PVD were not significantly associated with flap loss. CONCLUSIONS:The RSAF remains a safe salvage option for patients with DM or PVD but should be used with caution in smokers. Technical modifications to minimize pedicle compression significantly reduce rates of partial necrosis.

PURPOSE/OBJECTIVE:To date, no clear evidence-based guidelines exist pertaining to the ideal timing to perform surgical treatment of orbital fractures. The purpose of this study was to determine if early treatment of orbital fractures resulted in better patient outcomes. MATERIALS AND METHODS/METHODS:tests were performed to determine differences in clinical outcomes between early and late operative repair. RESULTS:Of the 1,160 articles reviewed, 20 met the inclusion criteria. Surgery performed less than 2 weeks after injury was significantly associated with greater odds of complete recovery of symptoms (odds ratio [OR], 6.9 [95% confidence interval (CI), 1.35-35.06]), as well as a lower incidence of postoperative diplopia (OR, 0.3 [95% CI, 0.1-0.9]) and enophthalmos (OR, 0.2 [95% CI, 0.1-0.9]). Repair performed less than 30 days after injury was associated complete resolution of preoperative motility restriction (OR, 24.6 [95% CI, 1.30-462.34]) as well as diplopia. CONCLUSIONS:Differences in the timing of surgery and definition of patient outcomes, as well as variations in methods of evaluating postoperative outcomes, potentiate the risk of bias and warrant downgrading of the quality of evidence in a study. The timing of repair varied among 2, 4, and 8 weeks after injury. However, a short time to surgical intervention was significantly associated with resolution of vertical dystopia, postoperative enophthalmos, and motility restriction.

BACKGROUND: The lateral femoral circumflex artery (LFCA) system, which supplies the anterolateral thigh (ALT) flap territory, offers a plethora of tissue types for composite, functional reconstruction. However, the ability to include a reliable and flexible osseous component is limited. Based on cadaveric dissections, we describe an isolated LFCA branch to the femur separate from the vastus intermedius that can be included in ALT flap harvest in cases requiring bony reconstruction. METHODS: Cadaveric dissection was undertaken to define the LFCA vascular system with specific dissection of the proximal branches of the descending branch of the LFCA (db-LFCA) to define any muscular, periosteal, and/or osseous branches to the femur. RESULTS: Six thighs in four cadavers were dissected. Consistent in all specimens, there was an isolated branch extending distally, medially, and posteriorly from the proximal LFCA and entering the periosteum of the femur. In five specimens, the identified branch to the femur was located approximately 1-cm distal to the rectus femoris branch of the LFCA and approximately 1-cm proximal to a separate branch entering and supplying the vastus intermedius. In one specimen, there was a common trunk. The length of this branch from the origin at the LFCA to insertion into the femoral periosteum was approximately 6 to 8 cm. CONCLUSION/CONCLUSIONS: There appears to be a consistent and reliable branch to the femur based on the proximal LFCA that may be included in ALT flap harvest, adding even more versatility, as another option in complex cases requiring composite reconstruction, including bone.

PURPOSE/OBJECTIVE:To the best of our knowledge, no studies have compared the patient profiles for 1- versus 2-team surgery within head and neck oncosurgery. PATIENTS AND METHODS/METHODS:A retrospective study of the data from 2968 patients who had undergone concurrent head and neck extirpative and reconstructive surgery in the National Surgical Quality Improvement Program (2010 to 2017) was conducted. Patients were stratified into 1- and 2-team surgery groups, and the demographic data were compared. Univariate analyses of the outcomes before and after propensity score matching were conducted. RESULTS:Most ablative and reconstructive head and neck procedures (68.5%) were performed using a 1-team approach. The patients who had undergone 2-team surgery were more likely to have a higher American Society of Anesthesiologists classification (P < .001), to require mandibulectomy (P < .001) or glossectomy (P < .001), and to receive a microvascular free flap (P < .001) but were less likely to require parotidectomy (P < .001) or to receive a rotational flap (P < .001). Before propensity score matching, the patients undergoing 2-team surgery had longer operative times (P < .001), longer postoperative stays (P < .001), greater rates of a return to the operating room (P = .001), and an increased rate of complications (P < .001). After propensity score matching, the 2-team approach continued to have longer operative times (P < .001) and an increased incidence of complications (P < .001) but no significant differences in the length of stay or rate of return to the operating room after Bonferroni's correction. CONCLUSIONS:Nationally, most head and neck ablative and reconstructive surgeries were completed by 1 team. More complicated reconstructive procedures involving microvascular free flaps have been more commonly performed by 2 teams, resulting in slightly longer operative times and greater associated complication rates.

BACKGROUND:The dimensions of the nipple-areolar complex (NAC) and its location on the chest wall are important aesthetic factors in male breast surgery. OBJECTIVES/OBJECTIVE:This study examines the perceptions of aesthetic surgeons and the general population for the aesthetically ideal position and size of male NAC. METHODS:An online survey was distributed to the American Society for Aesthetic Plastic Surgery (ASAPS) members and to the general population. Parameters queried included demographics for all participants, and academic details for ASAPS members. Both surveys included a male model picture with 16 separate choices for the NAC position from a frontal view, 5 choices for the NAC position from a lateral view, and 6 choices for the NAC dimensions. For all three sets of images, the participants were asked to rank the top three images they considered most "aesthetically pleasing" in descending order. A weighted scoring rule was created to quantitatively evaluate image choices. Standard statistical methods were used for analysis. RESULTS:The survey was completed by 272 ASAPS members and 4909 participants from the general population. The top three choices for NAC location on frontal view were the same for ASAPS members and the general population. The most popular NAC location on lateral view was the same for both groups, but the preferred locations were different between the two groups for the second and third choices. The most popular dimensions of the NAC were 2 cm (vertical) x 3 cm (horizontal) followed by 2 cm x 2 cm for both groups. Comparison of the three top image choices scores between different ethnic groups and individuals with different gender or sexual orientation demonstrated similar trends. CONCLUSION/CONCLUSIONS:This survey identified the preferred position and dimensions of the NAC on the male breast for plastic surgeons and the general population. These parameters should be taken into consideration when counseling males undergoing breast surgery.

BACKGROUND: After mastectomy and breast reconstruction, many patients experience upper extremity complications, such as pain, restriction in motion, and lymphedema. Despite an aesthetically satisfactory outcome, these occurrences can diminish a patient's postoperative quality of life. Several studies have investigated the causes and incidence of these complications. However, there is currently a paucity of data comparing postoperative upper extremity function according to reconstruction technique. METHODS: A review was performed of patients enrolled in a physical therapy (PT) program after mastectomy and immediate breast reconstruction. PT initial encounter evaluations were used to gather data on patients' postoperative upper extremity function. Hospital records were used to gather surgical and demographic data. For each patient, data were collected for each upper extremity that was ipsilateral to a reconstructed breast. Data were then compared between patients who underwent implant-based versus autologous deep inferior epigastric perforator flap reconstruction. RESULTS: = 0.022). Edema/swelling, axillary cording, and lymphedema girth measurements were similar between the two groups. CONCLUSION/CONCLUSIONS: Different techniques of breast reconstruction can result in different postoperative upper extremity complications. These data show specific areas where postoperative care and PT can be customized according to reconstruction type. Investigation is currently underway to determine the effect of PT on upper extremity function in these patients.

INTRODUCTION/BACKGROUND:Simulation is a standard component of residency training in many surgical subspecialties, yet its impact on knowledge and skills acquisition in plastic surgery training remains poorly defined. We evaluated the potential benefits of simulation-based cleft surgery learning in plastic surgery resident education through a prospective, randomized, blinded trial. METHODS:Thirteen plastic surgery residents were randomized to a digital simulator or textbook demonstrating unilateral cleft lip (UCL) repair. The following parameters were evaluated before (pre-intervention) and after (post-intervention) randomization: knowledge of surgical steps, procedural confidence, markings performance on a three-dimensional (3D) stone model, and surgical performance using a hands-on/high-fidelity 3D haptic model. Participant satisfaction with either educational tool was also assessed. Two expert reviewers blindly graded markings and surgical performance. Intra-class correlation coefficients (ICC) were calculated. Wilcoxon signed-rank and Mann-Whitney U tests were used. RESULTS:Interrater reliability was strong for pre-intervention and post-intervention grading of markings (ICC=0.97; p<0.001 and ICC=0.96; p<0.001) and surgical (ICC=0.83; p=0.002 and ICC=0.81; p=0.004) performance. Post-intervention surgical knowledge (40.3±4.4 vs. 33.5±3.7; p=0.03), procedural confidence (24.0±7.0 vs. 14.7±2.3; p=0.03), markings performance (8.0±2.5 vs. 2.9±3.1; p=0.03), and surgical performance (12.3±2.5 vs. 8.2±2.3; p=0.04) significantly improved in the digital simulation group compared to pre-intervention, but not in the textbook group. All participants were more satisfied with the digital simulator as an educational tool (27.7±2.5 vs. 14.4±4.4; p<0.001). CONCLUSIONS:We present evidence suggesting that digital cognitive simulators lead to significant improvement in surgical knowledge, procedural confidence, markings performance, as well as surgical performance.

Over 115 000 people are waiting for life-saving organ transplants, of whom a small fraction will receive transplants and many others will die while waiting. Existing efforts to expand the number of available organs, including increasing the number of registered donors and procuring organs in uncontrolled environments, are crucial but unlikely to address the shortage in the near future and will not improve donor/recipient compatibility or organ quality. If successful, organ bioengineering can solve the shortage and improve functional outcomes. Studying manufactured organs in animal models has produced valuable data, but is not sufficient to understand viability in humans. Before risking manufactured organ experimentation in living humans, study of bioengineered organs in recently deceased humans would facilitate evaluation of the function of engineered tissues and the complex interactions between the host and the transplanted tissue. Although such studies do not pose risk to human subjects, they pose unique ethical challenges concerning the previous wishes of the deceased, rights of surviving family members, effective operation and fair distribution of medical services, and public transparency. This article investigates the ethical, legal and social considerations in performing engineered organ research on the recently deceased.
