BACKGROUND:The purpose of this study was to compare the commonly used fat grafting techniques-Telfa rolling and a closed washing system-in breast reconstruction patients. METHODS:Consecutive patients undergoing fat grafting were retrospectively reviewed and grouped by technique. Patients with less than 180 days of follow-up were excluded. Demographics, operative details, and complications were compared using univariate analysis with significance set at p < 0.05. RESULTS:Between January of 2013 and September of 2017, 186 women underwent a total of 319 fat grafting procedures. There was no difference in demographics, number of procedures performed, volume of fat grafted, and number of days after reconstruction that fat grafting was performed between groups (p > 0.05). Telfa rolling patients had longer operative times for second fat grafting procedures (implant exchange often completed prior) [100.0 minutes (range, 60.0 to 150.0 minutes) versus 79.0 minutes (range, 64.0 to 94.0 minutes); p = 0.03]. Telfa rolling breasts had more palpable masses requiring imaging (26.0 percent versus 14.4 percent; p = 0.01) and an increased incidence of fat necrosis (20.6 percent versus 8.0 percent; p < 0.01). The closed washing system was found to be an independent predictor of decreased rates of imaging-confirmed fat necrosis (OR, 0.29; p = 0.048). There was no difference in fat necrosis excision or cancer recurrence between the groups. CONCLUSION/CONCLUSIONS:The closed washing system was independently associated with decreased rates of imaging-confirmed fat necrosis compared to Telfa rolling without an increase in other complications. CLINICAL QUESTION/LEVEL OF EVIDENCE/METHODS:Therapeutic, III.

OBJECTIVES/OBJECTIVE:To evaluate the clinical outcomes, histological parameters, and bone nanomechanical properties around implants retrieved from healthy and metabolic syndrome (MS) patients. METHODS:Twenty-four patients with edentulous mandibles (12/condition), received four implants between the mental foramina. An additional implant prototype was placed for retrieval histology. The following clinical outcomes were evaluated: insertion torque (IT), implant stability quotient (ISQ) values at baseline and after 60 days of healing, and implant survival. The prototype was retrieved after the healing and histologically processed for bone morphometric evaluation of bone-to-implant contact (%BIC) and bone area fraction occupancy (%BAFO), and bone nanoindentation to determine the elastic modulus (Em) and hardness (H). Descriptive statistical procedures and survival tests were used to analyze the data. RESULTS:The final study population was comprised of 10 women and 11 men (∼64 years). A total of 105 implants were placed, 21 retrieved for histology. Implant survival rates were similar between groups (>99 %). Similarly, IT and ISQ analyses showed no significant association with systemic condition (p > 0.216). Histological micrographs depicted similar bone morphology, woven bone, for both conditions. While MS (33 ± 5.3 %) and healthy (39 ± 6.5 %) individuals showed no significant difference for %BIC (p = 0.116), significantly higher %BAFO was observed for healthy (45 ± 4.6 %) relative to MS (30 ± 3.8 %) (p < 0.001). No significant differences on bone nanomechanical properties was observed (p > 0.804). CONCLUSIONS:Although no significant influence on clinical parameters and bone nanomechanical properties was observed, MS significantly reduced bone formation in the peri-implant area in the short-term. CLINICAL SIGNIFICANCE/CONCLUSIONS:A lower amount of bone formation in the peri-implant area was observed in comparison to healthy patients, although the other short-term clinical outcomes were not significantly different. Considering the escalating prevalence of MS patients in need for implant treatment, it becomes crucial to understand bone-to-implant response to determine the ideal loading time in this population.

The anterior chest wall is commonly involved in pediatric burn injuries. In women, deep thermal injuries may result in damage to the breast bud and breast skin, which can disrupt breast development and result in long-term deformities. In adulthood, the techniques frequently applied to correct these deformities focus on scar release in combination with skin grafting and implant-based procedures; however, these techniques often result in suboptimal aesthetic outcomes. In this report, we present superior outcomes from applying an autologous breast reconstruction technique to this challenging problem.

Due to the high complication rate of panniculectomies, preoperative risk stratification is imperative. This study aimed to assess the predictive value of the 5-item modified frailty index (mFI-5) for postoperative complications in the elderly following panniculectomy.

BACKGROUND:The gender disparity between the number of female and male chairs and program directors has been previously established. The aim of this study was to determine whether any differences in objective credentials existed between male and female plastic surgery department chairs/division chiefs and program directors. METHODS:Information about each plastic surgery program director and chair/chief was extracted from the websites of all institutions affiliated with a plastic surgery residency program. For each individual, information about the length of their career, number of fellowships completed, and number of publications was recorded. The two-tailed t test was used to compare differences between male and female chairs and program directors. RESULTS:A total of 99 chairs were recorded, of which nine (9.1 percent) were female. Of the 99 program directors, 13 (13.1 percent) were female. There was no difference in the number of years in practice or number of fellowships between men and women for either position. On average, male chairs had significantly fewer publications than female chairs (71.9 versus 128; p < 0.05). There was no significant difference in the number of publications between male and female program directors. Compared to program directors, chairs had significantly more years in practice and numbers of publications, which held true for both men and women. CONCLUSIONS:Women are not only underrepresented in the department chair and program director positions, but also possess higher qualifications that may reflect differences in standards for promotion and appointment. Additional research is needed to elucidate the reasons behind the observed differences in qualifications.

AIM/OBJECTIVE:Die silicone materials are used to build chairside composite restorations. The purpose of this study was to compare the flowability, dimension accuracy, and tear strength of four elastomeric die materials. MATERIAL AND METHODS/METHODS:Materials were divided into four groups: Mach-2 (M2), Scan Die (SD), GrandioSO Inlay System (GIS), and Impregum-F (IM). Flowability analysis was carried out using the shark fin test (SFT). For dimension accuracy, impressions were taken from a premolar Class I preparation and an elastomeric model was cast. Composite resin restorations were built and positioned into the premolar for gap measurement. The mean gap length was divided into three levels: acceptable (A), not acceptable (NA), and misfit (M). For tear strength, strip specimens were made with a V-shaped notch (n = 6). The specimens were tested in a universal machine until tear. All data were analyzed statistically with a confidence interval of 95%. RESULTS:GIS showed the lowest flowability values, with no differences between IM, M2, and SD. For dimension accuracy, IM showed 100% 'A' gap values, followed by M2 (80%), SD (60%), and GIS (60%). For tear strength, IM showed the highest values, followed by M2, GIS, and SD. CONCLUSIONS:M2, SD, and IM had similar flowability, while GIS had the lowest. IM presented higher tear strength than M2, followed by GIS and SD. IM showed the highest degrees of acceptable gap filling, followed by M2.

Telemedicine use in the field of wound care had been increasing in popularity when the novel coronavirus 2019 paralyzed the globe in early 2020. To combat the constraints of healthcare delivery during this time, the use of telemedicine has been further expanded. Although many limitations of telemedicine are still being untangled, the benefits of virtual care are being realized in both inpatient and outpatient settings. In this article, the advantages and disadvantages of telemedicine are discussed through two case examples that highlight the promise of implementation during and beyond the pandemic.
