RESUMO
Breast sensation plays a significant role in the safety and quality of life of women who undergo mastectomy and reconstruction. In 1992, Slezak et al. introduced the concept of abdominal flap neurotization to improve sensation of the reconstructed breast. Over the next 30 years, numerous studies iterated on Slezak's technique, suggesting technical modifications and new methodologies for assessing sensory recovery. Despite evidence that reinnervation increases patient satisfaction following autologous breast reconstruction, abdominal flap neurotization remains a rarely performed procedure. In this article, we review the evolution of flap neurotization in breast reconstruction and describe our approach to facilitating sensory recovery of the breast while limiting donor site morbidity.
RESUMO
BACKGROUND: Individual outcomes may not accurately reflect the quality of perioperative care. Textbook outcomes (TOs) are composite metrics that provide a comprehensive evaluation of hospital performance and surgical quality. This study aimed to investigate the prevalence and predictors of TOs in a multi-institutional cohort of patients who underwent breast reconstruction with deep inferior epigastric artery perforator flaps. METHODS: For autologous reconstruction, a TO was previously defined as a procedure without intraoperative complications, reoperation, infection requiring intravenous antibiotics, readmission, mortality, systemic complications, operative duration ≤12 hours for bilateral and ≤10 hours for unilateral/stacked reconstruction, and length of stay (LOS) ≤5 days. We investigated associations between patient-level factors and achieving a TO using multivariable regression analysis. RESULTS: Of 1000 patients, most (73.2%) met a TO. The most common reasons for deviation from a TO were reoperation (9.6%), prolonged operative time (9.5%), and prolonged LOS (9.2%). On univariate analysis, tobacco use, obesity, widowed/divorced marital status, and contralateral prophylactic mastectomy or bilateral reconstruction were associated with a lower likelihood of TOs (P < 0.05). After adjustment, bilateral prophylactic mastectomy (odds ratio [OR], 5.71; P = 0.029) and hormonal therapy (OR, 1.53; P = 0.050) were associated with a higher likelihood of TOs; higher body mass index (OR, 0.91; P = <0.001) was associated with a lower likelihood. CONCLUSION: Approximately 30% of patients did not achieve a TO, and the likelihood of achieving a TO was influenced by patient and procedural factors. Future studies should investigate how this metric may be used to evaluate patient and hospital-level performance to improve the quality of care in reconstructive surgery.

INTRODUCTION: SARS-CoV-2 (COVID-19) infection has been described as a cause of systemic hypercoagulability and a risk factor for the development of venous thromboembolism (VTE). Whereas some multispecialty studies have proposed a link between COVID-19 and postoperative thrombosis, other single-specialty studies have found no such association. We utilized a large national database to determine whether prior COVID-19 infection was associated with the incidence of VTE following common plastic surgery operations. METHODS: The Merative™ MarketScan® Research Databases were used to identify female patients who underwent index abdominal panniculectomy, breast reduction, autologous breast reconstruction, or implant-based breast reconstruction procedures between 2020 and 2021. International Classification of Disease, tenth edition (ICD-10) codes were used to identify patients diagnosed with COVID-19 preoperatively and those who experienced a VTE in the 90 days postoperatively. Propensity score matching and multivariable logistic regression were used to determine any independent association between COVID-19 and postoperative VTE. RESULTS: Twenty-four thousand two hundred and twenty-eight patients met inclusion criteria. Mean age at time of surgery was 44 years. Six percent carried a preoperative COVID-19 diagnosis, and postoperative VTE occurred in 1.3%. In a propensity-score-matched analysis of 2754 patients, COVID-19 did not significantly correlate with incidence of postoperative VTE (P = 0.463). Compared with a matched prepandemic cohort (14,151 patients), the incidence of VTE did not increase following any of the four studied procedures during the COVID-19 pandemic. CONCLUSION: This analysis of a national insurance claims database provides evidence against a link between resolved COVID-19 infection and VTE within 90 days of four common plastic surgery operations.

The development of electric vehicles (EVs) has introduced novel technologies and manufacturing processes that expose workers to new risks of burn injury. We identified six patients who were admitted to our burn center for injuries that occurred while working in EV manufacturing facilities. The burns fell into three categories: flash flame burns due to lithium-ion battery explosions, high-voltage electrical injuries, and burns caused by contact with molten metal. Recognizing these recurrent patterns of injury should inform future prevention efforts and prepare health systems to evaluate and treat patients burned in EV manufacturing.
RESUMO
BACKGROUND: Numerous studies have shown that obesity is a risk factor for postoperative complications following breast reconstruction. Hence, obesity has traditionally been considered a relative contraindication to microsurgical breast reconstruction. In this study, we investigated the impact of obesity on outcomes following microsurgical breast reconstruction. METHODS: A retrospective analysis of 200 consecutive patients who underwent microsurgical breast reconstruction with free abdominal flaps was performed. Subjects were divided into Nonobese (body mass index [BMI] < 30 kg/m2) and Obese (BMI ≥ 30 kg/m2) cohorts. Univariate and multivariate analyses were performed to evaluate differences in patient characteristics, complication rates, and efficiency metrics between the two groups. RESULTS: Of the 200 subjects included in the study, 128 were Nonobese, 72 were Obese. The prevalence of diabetes (3.9 vs. 16.9%, p = 0.002) and hypertension (14.7 vs. 39.4%, p < 0.001) were significantly greater in the Obese cohort. Among unilateral reconstructions, postoperative length of stay (LOS) was longer among Obese patients (3.1 vs. 3.6 days, p = 0.016). Seroma occurred more frequently in Obese patients following bilateral reconstruction (5.7 vs. 0.0%, p = 0.047). Otherwise, there were no significant differences in complication rates between the groups. On multivariate analysis, BMI was not independently associated with complications, LOS, or operative time. CONCLUSION: The improvements in clinical and patient-reported outcomes that have been associated with postmastectomy breast reconstruction do not exclude obese women. This study indicates that microsurgical breast reconstruction can be performed safely and efficiently in patients with obesity.
RESUMO
BACKGROUND: Hybrid breast reconstruction combines free tissue transfer with implant placement. Various mesh products have been successfully used to secure the implant position in these reconstructions. In this study, the authors investigate the impact of mesh type on long-term outcomes following hybrid breast reconstruction. METHODS: A retrospective analysis of all patients with at least 24 months of follow-up after immediate bilateral prepectoral hybrid breast reconstruction was performed. Univariate and multivariable regression analyses were used to evaluate long-term outcomes and compare breasts reconstructed with polyglactin mesh versus acellular dermal matrix (ADM). RESULTS: Thirty-nine patients (78 breasts) who underwent hybrid breast reconstruction with an average follow-up period of 50.4 months (range, 27 to 73 months) were included in the study. Post-operative complications included hematoma [n = 2 (2.6 percent)], mastectomy skin necrosis [n = 12 (15.4 percent)], and fat necrosis [n = 6 (7.7%)]. There were no instances of implant infection, implant exposure, or flap failure. Polyglactin mesh and ADM were used in 24 breasts and 54 breasts, respectively. Implant malposition and capsular contracture occurred more frequently in the polyglactin cohort leading to 10 (41.7 percent) instances of re-operation for implant replacement compared to only 1 (1.9 percent) in the ADM cohort (p < 0.001). On multivariable regression analysis, polyglactin mesh was associated with a 36-fold greater probability of requiring implant replacement compared to ADM (p = 0.006). CONCLUSIONS: ADM (vs. polyglactin mesh) is associated with lower rates of capsular contracture and implant malposition in the context of hybrid breast reconstruction.
RESUMO
Necrosis of the nipple-areolar complex (NAC) is a major complication of breast surgery that most commonly results from venous congestion. Several conservative rescue therapies have been proposed for relieving NAC congestion, but each carries certain drawbacks, including cost and side effect profile. In this study, we evaluated the effectiveness of topical dimethyl sulfoxide (DMSO), an inexpensive compound with vasodilatory, free radical scavenging, and antiinflammatory properties in rescuing congested NACs. Methods: We conducted a review of all 15 patients treated with DMSO for NAC congestion at our institution between May 2019 and October 2020. DMSO was applied in liquid form on a soaked gauze pad in the hospital; patients were instructed to apply a DMSO cream to the NAC twice a day following discharge. Patient characteristics and data related to DMSO treatment and NAC healing were compared via univariate analysis. Results: Eighteen congested NACs from 15 patients who underwent mastectomy, breast reduction, mastopexy, or breast reconstruction were treated with DMSO. Of the 18 treated NACs, 15 healed with DMSO treatment alone. The average length of DMSO treatment was 9.4 ± 8.5 days (mean ± standard deviation); NAC healing took place over 9.9 ± 9.6 days. There were no complications related to DMSO treatment. Conclusions: This pilot study shows that DMSO may be an effective topical treatment for NAC congestion following breast surgery. Given its low cost, ease of application, and lack of side effects, future studies should prospectively compare DMSO against other topical treatments, like nitroglycerin ointment.
RESUMO
BACKGROUND: Textured tissue expanders (TTEs) were introduced to limit migration and reduce capsular contracture, which were inherent to smooth tissue expanders (STEs). Previous reports suggest that textured devices have increased rates of bacterial contamination and biofilm formation in comparison with smooth devices. Recently, the relative increased association of anaplastic large cell lymphoma (ALCL) with textured versus smooth devices has led to increased adoption of smooth devices. The aim of our study is to evaluate the post-operative surgical site infection (SSI) rates of STEs versus TTEs. METHODS: A retrospective case series was conducted at a single academic teaching hospital from April 2016 to December 2019. The primary outcome variable was the development of a post-operative SSI. RESULTS: One hundred seventy-seven breasts underwent reconstruction with TTEs and 109 breasts underwent reconstruction with STE. In total, 54 SSIs were recorded (n = 34 TTE; n = 20 STE), with the majority of infections occurring within the first 30 post-operative days (TTE 65%, STE 70%). There was no statistically significant difference in overall post-operative infection rates between TTE and STE groups when broken down into the following time points: <30 day, 30-60 days, and >90 days (p = 0.924). There was no statistically significant difference between infection type (superficial vs. deep, p = 0.932), infection management (medical, surgical, or both, p = 0.409) or salvage results (p = 0.078) seen in STE versus TTE cohort. On multivariate analysis, seroma history was associated with SSI development (OR 3.18, p = 0.041). CONCLUSION: There was no significant difference in the rate of post-operative SSI following breast reconstruction with STE relative to TTE.

BACKGROUND: Depression is a leading cause of disability worldwide. Preliminary evidence suggests that glabellar onabotulinumtoxinA injections improve depression scores with few side effects compared to current first-line antidepressant medications. The authors' review reports on these studies, hypothesizing that glabellar onabotulinumtoxinA injections can be an alternative safe and effective treatment for depression. METHODS: A systematic review and meta-analysis of the relevant literature was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The PubMed, Cochrane Library, Embase, and Scopus databases were searched in August of 2020 using the keywords ["botox" OR "botulinum"] AND ["mood" OR "depression"] for articles published between 1980 and 2020. Prospective studies and randomized controlled trials on the use of glabellar onabotulinumtoxinA injections for the primary purpose of treating depression were considered. The primary endpoint for the meta-analysis was the mean difference in primary depression scores after treatment, along with a second endpoint of the standardized mean difference in depression scores among treated patients including all nine studies. RESULTS: Of the 499 reviewed articles, nine studies were included that reported improvement in mean depression scores from baseline. All five randomized controlled trials reported an improvement in mean depression scores at 6 weeks after treatment, with a weighted average change of -8.39 points ( p < 0.0001). The aggregate standardized mean difference from baseline to the primary endpoint across all nine prospective studies was -1.61 SD ( p < 0.0001). CONCLUSION: Meta-analysis and systematic review of the included studies provide support for an antidepressant effect of glabellar onabotulinumtoxinA injections.

Although polydactyly is quite common in general, preaxial polydactyly of the foot is rare (0.4 per 10,000 patients) and specifically associated with certain congenital abnormalities and syndromes, which can include craniosynostosis, corpus callosum agenesis, and renal malformations. We present 2 recent cases of preaxial polydactyly of the foot that highlight the importance of maintaining a high level of suspicion for associated abnormalities in these patients. The first patient, who presented with supernumerary preaxial digits on both feet, pre- and postaxial polydactyly of the hands, was also macrocephalic and hyperteloric; this presentation strongly suggested a diagnosis of Greig cephalopolysyndactyly, a GLI3-variant syndrome. The second patient, who had 2 preaxial digits on one foot, was found to also have a horseshoe kidney, a malformation that has been associated with limb defects as part of an acrorenal syndrome. These cases emphasize the importance of a thorough clinical approach to patients with preaxial polydactyly of the foot. Although many patients with this anomaly may be well known to geneticists, a child may be referred to a plastic surgeon for reconstruction of what is thought to be an isolated cosmetic or local functional issue. Plastic surgeons should be aware of the complex nature of preaxial polydactyly of the foot and potential syndromic presentation.
RESUMO
BACKGROUND: Neoplasms of the retroperitoneum that contain a major fat component may represent either benign entities, such as lipomas or angiomyolipomas, or malignancy such as liposarcoma. Distinguishing these diagnoses has important implications for management. While liposarcomas often stain positively for MDM2 and CDK4 proteins, absence of these markers can lead to diagnostic and management challenges. METHODS: We examined three cases in our institution of fat-containing masses of the retroperitoneum that lacked MDM2 and CDK4 markers to highlight the challenges in diagnosing and managing these cases. A thorough review of the literature examining radiologic and histologic features that can be used to determine that diagnosis was conducted and summarized. RESULTS: The three cases we present represent the three main diagnostic entities that can be found in among fatty tumors of the retroperitoneum: lipoma, angiomyolipoma, and liposarcoma. While radiologic features and analysis of histology helped to inform management, these cases in conjunction with the literature also illustrate the limitations of the diagnostic work up and importance also factoring the biologic behavior of the tumor in its management. CONCLUSION: Fat-containing tumors of the retroperitoneum that do not stain for MDM2 or CDK4 can pose a diagnostic challenge. Assessing radiologic and pathologic features in conjunction with the biologic behavior of these tumors should inform their management.
