Background In patients with head and neck squamous cell carcinoma (HNSCC), disease recurrence remains a significant obstacle to long-term survival. If possible, surgical salvage with reconstruction remains the best treatment option for patients with recurrence. Currently, there is no literature discussing whether age should preclude microvascular reconstruction in these patients. We hypothesize that older age alone does not affect outcomes. Methods A retrospective chart review of patients with HNSCC at our institution between 2008 and 2015 was performed. Patients were included if they underwent simultaneous resection and flap reconstruction for recurrent HNSCC. Data collected included age, sex, primary site, type of reconstruction, previous treatments, postoperative complications (systemic and reconstructive), and overall survival. Results A total of 65 patients met inclusion criteria for the review: 42 (64.6%) patients ≤70 years and 23 (35.4%) patients > 70 years. Overall survival was not significantly different between the younger and older groups (p = 0.199). Five-year survival was 60.1% in the younger group and 46.8% in the older group. No significant difference was found in reconstructive complication rates (p = 0.179) or systemic complication rates (p = 0.241) between the two groups. Multivariate logistic regression analysis further showed no significant association between patients' age (≤70 years or > 70 years) and reconstructive complications (p = 0.396) or systemic complications (p = 0.119). Conclusion Age is not significantly associated with complications among patients undergoing resection and reconstruction for recurrent HNSCC. Microvascular reconstruction remains a feasible option in older patients with recurrent HNSCC. Advanced age alone should not preclude the surgical management of recurrent HNSCC.

BACKGROUND: There is controversy regarding the treatment of young patients with unilateral craniofacial microsomia and moderate dysmorphism. The relative indication for mandibular distraction in such patients poses several questions: Is it deleterious in the context of craniofacial growth and appearance? This study was designed to address these questions. METHODS: A retrospective review of patients undergoing mandibular distraction by a single surgeon between 1989 and 2010 was conducted. Patients with "moderate" unilateral craniofacial microsomia (as defined by Pruzansky type I or IIa mandibles) and follow-up until craniofacial skeletal maturity were included for analysis. Patients were divided into two cohorts: satisfactory and unsatisfactory results based on photographic aesthetic evaluation by independent blinded observers at the initial presentation and at the age of skeletal maturity. Clinical variables were analyzed to detect predictors for satisfactory distraction. RESULTS: Nineteen patients were included for analysis. The average age at distraction was 68.2 months and the average age at follow-up was 19.55 years. Thirteen patients (68.4 percent) had Pruzansky type IIA and six patients (31.6 percent) had Pruzansky type I mandibles. Twelve patients (63.2 percent) had satisfactory outcomes, whereas seven patients (36.8 percent) had unsatisfactory outcomes. Comparing the two cohorts, patients with satisfactory outcomes had distraction at an earlier age (56.4 months versus 89.8 months; p = 0.07) and a greater percentage overcorrection from craniofacial midline (41.7 percent versus 1.8 percent; p = 0.003). CONCLUSION: Mandibular distraction is successful in patients with mild to moderate dysmorphism, provided that there is a comprehensive clinical program emphasizing adequate mandibular bone stock, proper vector selection, planned overcorrection, and comprehensive orthodontic management.

Background Higher body mass index (BMI) has been shown to increase postoperative complications in autologous breast reconstruction. However, the correlation with flap weight is unknown. Here, we explore the relationship of flap weights and complication rates in patients undergoing microvascular breast reconstruction. Methods Retrospective chart review identified all patients undergoing microvascular breast reconstruction with abdominally based flaps at a single institution between November 2007 and April 2013. Breasts with documented flap weight and 1-year follow-up were included. Patients undergoing stacked deep inferior epigastric perforator flaps were excluded. Breasts were divided into quartiles based on flap weight and examined by demographics, surgical characteristics, complications, and revisions. Results A total of 130 patients undergoing 225 flaps were identified. Patients had a mean age of 50.4 years, mean BMI of 27.1 kg/m2, and mean flap weight of 638.4 g (range: 70-1640 g). Flap weight and BMI were directly correlated. Flaps were divided into weight-based quartiles: first (70-396 g), second (397-615 g), third (616-870 g), and fourth (871-1640 g). There were no associations between flap weight and incidences of venous thrombosis, arterial thrombosis, hematoma, flap loss, fat necrosis, or donor site hernia. However, increased flap weight was associated with increased rate of donor site wound healing problems in both univariate and multivariate analysis. Conclusions Increased flap weight is not associated with added flap complications among patients undergoing microvascular breast reconstruction, however, patients with flaps of 667.5 g or more are more likely to have donor site healing problems. The success and evidence contrary to previous studies may be attributed to surgeon intraoperative flap choice.

BACKGROUND: Given the complexity of microsurgical breast reconstruction, there are many opportunities to improve both surgical efficiency and outcomes. The use of two operating surgeons has been employed, but the outcomes are unproven. In this study, the authors compare the outcomes of patients undergoing microsurgical breast reconstruction with one operating surgeon to those with two surgeons. METHODS: A retrospective review of all patients undergoing microsurgical breast reconstruction between July of 2011 and January of 2014 at a single academic institution was conducted. Patients were divided into two cohorts: those undergoing reconstruction with one surgeon and those having reconstruction with two surgeons. Once identified, patients were analyzed and outcomes were compared. RESULTS: A total of 157 patients underwent 248 microsurgical breast reconstructions during the study period. One hundred three patients (170 flaps) had two surgeons and 54 patients (78 flaps) had one surgeon. Patients undergoing unilateral and bilateral reconstructions with two surgeons had decreased mean operating room time by 60.1 minutes and 134 minutes (p < 0.001) and length of stay by 1.8 days and 1.3 days (p < 0.05), when compared to a single surgeon. Additionally, patients with one surgeon were more likely to have postoperative donor-site breakdown at 5.1 percent (n = 4) versus 0.6 percent (n = 1) (p = 0.0351). CONCLUSIONS: The use of two operating surgeons has demonstrable effects on the outcomes of microsurgical breast reconstruction. The addition of a second surgeon significantly decreases operating room time and shortens hospital length of stay in both unilateral and bilateral reconstruction. It also significantly decreases donor-site wound healing complications. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Lymphedema is a chronic, progressive condition caused by an imbalance of lymphatic flow. Upper extremity lymphedema has been reported in 16-40% of breast cancer patients following axillary lymph node dissection. Furthermore, lymphedema following sentinel lymph node biopsy alone has been reported in 3.5% of patients. While the disease process is not new, there has been significant progress in the surgical care of lymphedema that can offer alternatives and improvements in management. The purpose of this review is to provide a comprehensive update and overview of the current advances and surgical treatment options for upper extremity lymphedema.

Introduction While implementation of subspecializations may increase expertise in a certain area of treatment, there also exist downsides. Aim of this study was, across several disciplines, to find out if the technique of microsurgery warrants the introduction of a "Certificate of Added Qualifications (CAQ) in microsurgery." Methods An anonymous, web-based survey was administered to directors of microsurgical departments in Europe (n = 205). Respondents were asked, among other questions, whether they had completed a 12-month microvascular surgery fellowship and whether they believed a CAQ in microvascular surgery should be instituted. Results The response rate was 57%, and 33% of the respondents had completed a 12-month microvascular surgery fellowship.A total of 61% of all surgeons supported a CAQ in microsurgery. Answers ranged from 47% of support to 100% of support, depending on the countries surveyed. Discussion This is one of the few reports to evaluate the potential role of subspecialty certification of microvascular surgery across several European countries. The data demonstrate that the majority of directors of microsurgical departments support such a certificate. There was significantly greater support for a CAQ in microsurgery among those who have completed a formal microvascular surgery fellowship themselves. Conclusion This study supports the notion that further discussion and consideration of subspecialty certification in microvascular surgery appears necessary. There are multiple concerns surrounding this issue. Similar to the evolution of hand surgery certification, an exploratory committee of executive members of the respective medical boards and official societies may be warranted.

UNLABELLED:Surgical markings play a crucial role in the planning of plastic surgery procedures. However, despite their importance, they are often imprecise. For instance, when assessing patients in need of autologous fat grafting, surgeons often base markings on estimations of where volume deficiency exists and how much volume will correct the deficiency. In this article, the authors describe a novel approach to lipostructure, guided by a computer-based roadmap. A digital three-dimensional topographic surgical map is created using three-dimensional photography and analytic software and then projected as an image onto the patient in the operating room. This unique concept can be applied to most soft-tissue procedures in plastic surgery. CLINICAL QUESTION/LEVEL OF EVIDENCE:Therapeutic, V.

Background Surgical management of head and neck cancer is resource intensive and physiologically demanding. In patients with incurable disease, although the indications for surgery are not well defined, palliative benefit can be significant. The goal of this investigation was to compare outcomes of patients who underwent resection and reconstruction of head and neck cancer with curative intent with those who underwent similar procedures with palliative intent. Methods A retrospective review of patients who underwent reconstruction for head and neck cancer between 2008 and 2014 was conducted. Patients were divided into curative and palliative groups. Outcomes assessed included postoperative complications and survival. Results A total of 147 patients who underwent 156 operations met inclusion criteria (27 palliative and 129 curative). In both cohorts, the most common histology was squamous cell carcinoma (SCC) and the most common primary tumor site was the oral cavity. There was no significant difference between the cohorts in the rates of systemic and reconstructive complications, postoperative hospital length of stay, 30-day mortality, and flap survival. Overall survival in palliative patients was significantly shorter compared with curative patients (median OS, 6.2 months vs. 56.1 months, respectively; p < 0.0001). Among patients undergoing palliative surgery, patients without carotid involvement and those with non-SCC were significantly more likely to have longer survival. Conclusion Surgical resection with reconstruction is possible in head and neck oncologic patients undergoing palliative treatment. Palliative patients have similar short-term outcomes when compared with patients undergoing resection for curative intent. Quality-of-life and economic implications of these approaches deserve closer scrutiny.

BACKGROUND: Approximately 20 percent of women select autologous tissue for postmastectomy breast reconstruction, and most commonly choose the abdomen as the donor site. An increasing proportion of women are seeking muscle-sparing procedures, but the benefit remains controversial. It is therefore important to determine whether better outcomes are associated with these techniques, thereby justifying longer operative times and increased costs. METHODS: Patients from five North American centers were eligible if they underwent reconstruction by means of the deep inferior epigastric artery perforator (DIEP) flap, muscle-sparing free transverse abdominis myocutaneous (TRAM) flap, free TRAM flap, or the pedicled TRAM flap. Patients were sent the BREAST-Q. Demographics and complications were collected. RESULTS: The authors analyzed 1790 charts representing 670 DIEP, 293 muscle-sparing free TRAM, 683 pedicled TRAM, and 144 free TRAM patients with an average follow-up of 5.5 years. Flap loss did not differ by flap type. Partial flap loss was higher in pedicled TRAM compared with DIEP (p = 0.002). Fat necrosis was higher in pedicled TRAM compared with DIEP and muscle-sparing free TRAM (p < 0.001). Hernia/bulge was highest in pedicled TRAM (p < 0.001). Physical well-being (abdomen) scores were higher in DIEP compared with pedicled TRAM controlling for confounders. CONCLUSIONS: Complications and patient-reported outcomes differ when comparing abdominally based breast reconstruction techniques. The results of this study show that the DIEP flap was associated with the highest abdominal well-being and the lowest abdominal morbidity compared with the pedicled TRAM flap, but did not differ from muscle-sparing free TRAM and free TRAM flaps.

BACKGROUND: The authors assess the fiscal viability of complex head and neck reconstructive surgery by evaluating its financial reimbursement in the setting of resources used. METHODS: The authors prospectively assessed provider reimbursement for consecutive patients undergoing head and neck reconstruction. Total care time was determined by adding 15 minutes to the operative time for each postoperative hospital day and each postoperative follow-up appointment within the 90-day global period. Physician reimbursement was divided by total care time hours to determine an hourly rate of reimbursement. A control group of patients undergoing carpal tunnel release was evaluated using the same methods described. RESULTS: A total of 50 patients met the inclusion criteria for study. The payer was Medicaid for nine patients (18 percent), Medicare for 19 patients (38 percent), and commercial for 22 patients (44 percent). The average provider revenue per case was $3241.01 +/- $2500.65. For all patients, the mean operative time was 10.6 +/- 3.87 hours and the mean number of postoperative hospital days was 15.1 +/- 8.06. The mean reimbursement per total care time hour was $254 +/- $199.87. Statistical analysis demonstrated difference in reimbursement per total care time hour when grouped by insurance type (p = 0.002) or flap type (p = 0.033). Of the 50 most recent patients to undergo carpal tunnel release, the average revenue per case was $785.27. CONCLUSION: Total care time analysis demonstrates that physician reimbursement is not commensurate with resources used for complex head and neck reconstructive surgery.
