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.

A 50-year-old woman developed severe soft tissue atrophy of the hip following a triamincolone acetonide injection to the greater trochanteric bursa. Saline injection therapy was initially attempted without improvement and the defect was ultimately treated effectively with serial fat grafting. Adverse soft tissue reactions are rare but potentially devastating complications of corticosteroid injections, and the use of soluble steroid preparations and proper injection techniques can minimize the risk to surrounding tissue. Serial fat grafting represents a promising treatment option for severe cases of steroid-induced soft tissue atrophy.

BACKGROUND:Nipple-sparing mastectomy is associated with a higher risk of mastectomy skin-flap necrosis than conventional skin-sparing mastectomy. There are limited prospective data examining modifiable intraoperative factors that contribute to skin-flap necrosis after nipple-sparing mastectomy. METHODS:Data on consecutive patients undergoing nipple-sparing mastectomy between April 2018 and December 2020 were recorded prospectively. Relevant intraoperative variables were documented by both breast and plastic surgeons at the time of surgery. The presence and extent of nipple and/or skin-flap necrosis was documented at the first postoperative visit. Necrosis treatment and outcome was documented at 8-10 weeks after surgery. The association of clinical and intraoperative variables with nipple and skin-flap necrosis was analysed, and significant variables were included in a multivariable logistic regression analysis with backward selection. RESULTS:Some 299 patients underwent 515 nipple-sparing mastectomies (54.8 per cent (282 of 515) prophylactic, 45.2 per cent therapeutic). Overall, 23.3 per cent of breasts (120 of 515) developed nipple or skin-flap necrosis; 45.8 per cent of these (55 of 120) had nipple necrosis only. Among 120 breasts with necrosis, 22.5 per cent had superficial, 60.8 per cent had partial, and 16.7 per cent had full-thickness necrosis. On multivariable logistic regression analysis, significant modifiable intraoperative predictors of necrosis included sacrificing the second intercostal perforator (P = 0.006), greater tissue expander fill volume (P < 0.001), and non-lateral inframammary fold incision placement (P = 0.003). CONCLUSION:Modifiable intraoperative factors that may decrease the likelihood of necrosis after nipple-sparing mastectomy include incision placement in the lateral inframammary fold, preserving the second intercostal perforating vessel, and minimizing tissue expander fill volume.

To compare lower lip changes after Le Fort I advancement surgery in patients with a cleft. Single institution, retrospective review. Academic tertiary referral hospital. Skeletally mature patients with a cleft who underwent one-piece Le Fort I advancement surgery who had a lateral cephalogram or cone-beam computed tomography (CBCT) scan preoperatively and at least 6 months postoperatively. Patients who underwent concomitant mandibular surgery or genioplasty were excluded. 64 patients were included: 45 male and 19 female, 25 with BCLP and 39 with UCLP. The mean age at surgery was 18.4 years. Single jaw one-piece Le Fort I advancement surgery. Standard lateral cephalometric landmarks of the bony skeleton and soft tissue were compared before and after Le Fort I advancement. Pearson correlation coefficients (r) were calculated to measure the correlation between lower lip position and other soft and hard tissue changes. After comparable maxillary advancements [BCLP: 7.2 mm (95% CI: 6.2-8.3 mm), UCLP: 6.4 mm (95% CI: 5.7-7.0 mm)] the horizontal upper-to-lower lip discrepancy significantly improved in both groups. The lower lip became thinner and more posteriorly positioned. Changes in lower lip position correlated strongly with mandibular bony landmarks and moderately with upper lip position, but poorly with maxillary landmarks. Le Fort I advancement results in posterior displacement of the lower lip and better lip competence, thereby improving facial harmony. This lower lip change is not predictable by degree of maxillary advancement, and does not differ in patients with BCLP vs. UCLP.

As medicine becomes more complex, there is pressure for new and more innovative educational methods. Given the economic burden associated with in-person simulation, healthcare, including the realm of surgical education, has begun employing virtual reality (VR). Potential benefits of the addition of VR to surgical learning include increased pre-operative resident exposure to surgical techniques and procedures and better patient safety outcomes. However, these new technological advances, such as VR, may not replicate organic tissues or accurately simulate medical care and surgical scenarios, creating unrealistic pseudo-environments. Similarly, while advancements have been made, there are ongoing disparities concerning the utilization of these technologies. These disparities include aspects such as the availability of stable internet connections and the cost of implementing these technologies. In accordance with other innovative technologies, VR possesses upfront economic costs that may preclude equitable use in different academic centers around the world. As such, VR may further widen educational quality between high- and low-resource nations. This analysis integrates recent innovations in VR technology with existing discourse on global health and surgical equality. In doing so, it offers preliminary guidance to ensure that the implementation of VR occurs in an equitable, safe, and sustainable fashion.

OBJECTIVE:To provide recommendations for a comprehensive management approach for infants and children presenting with symptoms or signs of aspiration. METHODS:Three rounds of surveys were sent to authors from 23 institutions worldwide. The threshold for the critical level of agreement among respondents was set at 80 %. To develop the definition of "intractable aspiration," each author was first asked to define the condition. Second, each author was asked to complete a 5-point Likert scale to specify the level of agreement with the definition derived in the first step. RESULTS:Recommendations by the authors regarding the clinical presentation, diagnostic considerations, and medical and surgical management options for aspiration in children. CONCLUSION/CONCLUSIONS:Approach to pediatric aspiration is best achieved by implementing a multidisciplinary approach with a comprehensive investigation strategy and different treatment options.

Introduction: Open fractures with degloving injuries are commonly managed by serial debridements prior to definitive flap coverage in the United States (US). Some international institutions minimize the number of debridements prior to coverage. The purpose of this study was to compare clinical outcomes in patients with open tibia fractures requiring free flap coverage from institutions with differing debridement philosophies. Methods: This was a multi-site retrospective cohort study of patients treated at two US tertiary care facilities (serial debridement cohort) and one in India (early total debridement cohort) with Type IIIB or IIIC open tibia fractures requiring free tissue transfer. The number of debridements prior to flap coverage were recorded and primary outcomes were rates of infection, non-union, and flap failure. Fischer's exact tests were used to compare outcomes between the cohorts. Results: 80 patients were included, 44 from India and 36 from the US. Patients in the serial debridement cohort underwent more debridements prior to flap coverage (mean 3.64 vs 1.84, p < 0.001) and had significantly higher rates of infection and non-union compared to patients in the early total debridement cohort (p < 0.05). There were no differences in rates of flap failure between the cohorts. Conclusions: Patients with open tibia fractures treated at institutions favoring serial debridements underwent more debridements and had higher rates of infection and non-union compared to patients treated at a center favoring early total debridement. Serial debridements may not be necessary prior to flap coverage for open tibia fractures and the current practice should be further investigated.

OBJECTIVE:To define "high osteotomy" and determine the feasibility of performing this procedure. DESIGN/METHODS:Single institution, retrospective review. SETTING/METHODS:Academic tertiary referral hospital. PATIENTS, PARTICIPANTS/METHODS:34 skeletally mature, nonsyndromic patients with unilateral CLP who underwent Le Fort I osteotomy between 2013 and 2020. Patients with cone-beam computed tomography (CBCT) scans completed both pre- (T1) and post-operatively (T2) were included. Patients with bilateral clefts and rhinoplasty prior to post-operative imaging were excluded. INTERVENTIONS/METHODS:Single jaw one-piece Le Fort I advancement surgery. MAIN OUTCOME MEASURES/METHODS:Measurements of the superior ala and inferior turbinates were taken from the post-operative CBCT. RESULTS:The sample included 26 males and 8 females, 12 right- and 22 left-sided clefts. The inferior turbinates are above the superior alar crease at a rate of 73.53% and 76.48% on the cleft and non-cleft sides, respectively. One (2.9%) osteotomy cut was above the level of the cleft superior alar crease, and no cuts were above the level of the non-cleft superior ala. On average, the superior ala was 2.63 mm below the inferior turbinates. The average vertical distances from the superior alar crease and the inferior turbinates to the base of the non-cleft side pyriform aperture were 12.17 mm (95% CI 4.00-20.34) and 14.80 mm (95% CI 4.61-24.98), respectively. To complete a "high osteotomy," with 95% confidence, the cut should be 20.36 mm from the base of the pyriform aperture. CONCLUSIONS:A "high" osteotomy is not consistently possible due to the relationship between the superior alar crease and the inferior turbinate.
