Background The purpose of this investigation was to examine patients with low body mass index (BMI) regarding the feasibility to perform autologous breast reconstruction in such patients, as well as to determine optimal donor sites and evaluate outcomes accordingly. Patients and Methods All patients undergoing microsurgical breast reconstruction were divided into three cohorts based on BMI. Group 1 included patients with BMI greater than or equal to 22 kg/m2 and was defined "low-normal BMI." Patients with BMI 22 to 25 kg/m2 were placed in Group 2, labeled as "high-normal BMI." Group 3, defined as "overweight," included patients with BMI greater than 25 kg/m2, but less than 30 kg/m2. Patients were then analyzed based on demographics, breast cancer history, intraoperative details, complications, and revisionary surgeries. F-tests, chi-square goodness-of-fit tests, and Freeman-Halton extension of the Fisher exact tests were used for statistical analysis. Results During the study period, a total of 259 reconstructions were performed. Group 1 included 30 patients (n = 49 flaps), Group 2 included 58 patients (n = 98 flaps), and Group 3 included 69 patients (n = 112 flaps). Patients undergoing nipple-areolar sparing mastectomy were more likely to be in Groups 1 (39% [n = 19]) and 2 (37% [n = 37]) as compared with Group 3 (14.2% [n = 16]) (p < 0.001) as compared with the overweight cohort. Patients with increasing BMI were more likely to undergo abdominally based free flaps as compared with alternative donor sites (Group 1 = 2.26, Group 2 = 7.9, Group 3 = 27 [p < 0.001]). Conclusions Abdominally based free flaps are possible in the majority of patients, however alternative harvest sites have to be used more frequently in low BMI patients.

BACKGROUND: The free fibula osteocutaneous flap has become the criterion standard for reconstruction of complex mandibular defects. The authors present their institutional experience with optimization of flap contouring and inset using virtual planning and prefabricated cutting jigs. METHODS: All free fibula-based mandible reconstructions performed at the authors' institution using virtual planning technology between 2009 and 2012 were retrospectively analyzed. The authors evaluated a variety of patient and procedural variables and outcomes. A series of cases performed before virtual planning was reviewed for comparison purposes. RESULTS: Fifty-four reconstructions were performed in 52 patients. Patients were divided evenly between a private university-affiliated medical center and a large county hospital. The most common indications were malignancy (43 percent), ameloblastoma (26 percent), and osteonecrosis/osteomyelitis (23 percent). Thirty percent of patients had irradiation of the recipient site and 38 percent had previous surgery. Sixty-three percent of patients received dental implants, with 47 percent achieving functional dentition. Twenty-five percent of patients had immediate dental implant placement, and 9 percent had immediate dental restoration. Postoperative imaging demonstrated excellent precision and accuracy of flap positioning. Comparison with cases performed before virtual planning demonstrated increased complexity of flap design along with reduced operative time in the virtually planned group. CONCLUSIONS: Preoperative virtual planning along with use of prefabricated cutting jigs allows for precise contouring and positioning of microvascular fibula free flaps in mandibular reconstruction. Using this technique, the authors have achieved unprecedented rates of dental rehabilitation along with reduced operative times. The authors believe that virtual planning technologies are an emerging criterion standard in mandible reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

BACKGROUND: Reconstruction in the setting of prior breast irradiation is conventionally considered a higher-risk procedure. Limited data exist regarding nipple-sparing mastectomy in irradiated breasts, a higher-risk procedure in higher-risk patients. METHODS: The authors identified and reviewed the records of 501 nipple-sparing mastectomy breasts at their institution from 2006 to 2013. RESULTS: Of 501 nipple-sparing mastectomy breasts, 26 were irradiated. The average time between radiation and mastectomy was 12 years. Reconstruction methods in the 26 breasts included tissue expander (n = 14), microvascular free flap (n = 8), direct implant (n = 2), latissimus dorsi flap with implant (n = 1), and rotational perforator flap (n = 1). Rate of return to the operating room for mastectomy flap necrosis was 11.5 percent (three of 26). Nipple-areola complex complications included one complete necrosis (3.8 percent) and one partial necrosis (3.8 percent). Complications were compared between this subset of previously irradiated patients and the larger nipple-sparing mastectomy cohort. There was no significant difference in body mass index, but the irradiated group was significantly older (51 years versus 47.2 years; p = 0.05). There was no statistically significant difference with regard to mastectomy flap necrosis (p = 0.46), partial nipple-areola complex necrosis (p = 1.00), complete nipple-areola complex necrosis (p = 0.47), implant explantation (p = 0.06), hematoma (p = 1.00), seroma (p = 1.00), or capsular contracture (p = 1.00). CONCLUSION: In the largest study to date of nipple-sparing mastectomy in irradiated breasts, the authors demonstrate that implant-based and autologous reconstruction can be performed with complications comparable to those of the rest of their nipple-sparing mastectomy patients.

BACKGROUND: Acellular dermal matrix is a commonly used adjunct in implant-based breast reconstruction. Several investigations have shown increased complications associated with its use. Therefore, the authors' institution placed strict limitations on its use and transitioned to sterile "ready-to-use" acellular dermal matrix. The purpose of this investigation was to compare the infectious complications associated with aseptic versus sterile acellular dermal matrix. METHODS: A prospective study of all patients undergoing immediate implant-based breast reconstruction at a single academic medical center between November of 2010 and October of 2012 was conducted. AlloDerm (Life Cell Corporation, Branchburg, N.J.) was used as the source of acellular dermal matrix. Breasts were divided into three cohorts: total submuscular coverage, aseptic acellular dermal matrix, and sterile, ready-to-use acellular dermal matrix. Breasts were then compared based on demographic information, cancer qualities, and complications. RESULTS: A total of 546 reconstructed breasts met inclusion criteria: 64.3 percent (n = 351) with no acellular dermal matrix, 16.5 percent (n = 90) with aseptic matrix, and 19.2 percent (n = 105) with ready-to-use matrix. When comparing reconstructions with ready-to-use versus aseptic acellular dermal matrix, patients had a decrease in overall infection (8.5 percent versus 20.0 percent; p = 0.0088), major infection (4.7 percent versus 12.2 percent; p = 0.069), and need for explantation (1.9 percent versus 6.6 percent; p = 0.1470). When comparing patients undergoing reconstruction with ready-to-use matrix to total submuscular coverage, patients had similar overall infectious complications (8.5 percent versus 5.7 percent; p = 0.3602). Diabetes mellitus, seroma, mastectomy skin flap necrosis, and aseptic acellular dermal matrix were independent predictors of infectious complications. CONCLUSIONS: Ready-to-use acellular dermal matrix in immediate implant-based breast reconstruction provides a useful adjunct. In addition, it mitigates the risks of infectious complications when compared with aseptic acellular dermal matrix. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

BACKGROUND: Autologous microvascular breast reconstruction is an increasingly common procedure. While arterial anastomoses are traditionally being hand-sewn, venous anastomoses are often completed with a coupler device. The largest coupler size possible should be used, as determined by the smaller of either the donor or recipient vein. While its efficacy has been shown using 3.0-mm size and greater couplers, little is known about the consequences of using coupler sizes less than or equal to 2.5 mm. Methods: A retrospective chart review of patients undergoing autologous breast reconstruction was conducted at NYU Medical Center between November 2007 and November 2011. Flaps were divided into cohorts based on coupler size used: 2.0 mm, 2.5 mm, and 3.0 mm. Outcomes included incidence of arterial or venous insufficiency, hematoma, fat necrosis, partial flap loss, full flap loss, and need for future fat grafting. Results: One-hundred ninety-seven patients underwent 392 flaps during the study period. Patients were similar in age, type of flap, smoking status, and radiation history. Coupler size less than or equal to 2.0 mm was found to be a significant risk factor for venous insufficiency (P = 0.038), as well as for development of fat necrosis (P = 0.041) and future need for fat grafting (P = 0.050). In multivariate analysis, body mass index was found to be an independent risk factor for skin flap necrosis (P = 0.010) and full flap loss (P = 0.035). Conclusions: Complications were significantly increased in patients where couplers of 2.0 mm or less were used, therefore to be avoided whenever possible. When needed, more aggressive vessel exposure through rib harvest, the use of thoracodorsal vessels or hand-sewing the anastomosis should be considered in cases of internal mammary vein caliber of 2.0 mm or less.

BACKGROUND: Autologous breast reconstruction offers higher rates of patient satisfaction, but not all patients are ideal candidates, often due to inadequate volume of donor sites. Although autologous fat grafting is frequently used to augment volume and contour abnormalities in implant-based breast reconstruction, its clear utility in microsurgical breast reconstruction has yet to be defined. Here, we examined patients undergoing autologous microsurgical breast reconstruction with and without the adjunct of autologous fat grafting to clearly define utility and indications for use. METHODS: A retrospective review of all patients undergoing autologous breast reconstruction with microvascular free flaps at a single institution between November 2007 and October 2011 was conducted. Patients were divided into 2 groups as follows: those requiring postoperative fat grafting and those not requiring fat grafting. Patient demographics, indications for surgery, history of radiation therapy, patient body mass index, mastectomy specimen weight, need for rib resection, flap weight, and complications were analyzed in comparison. RESULTS: Two hundred twenty-eight patients underwent 374 microvascular free flaps for breast reconstruction. One hundred (26.7%) reconstructed breasts underwent postoperative fat grafting, with an average of 1.12 operative sessions. Fat was most commonly injected in the medial and superior medial poles of the breast and the average volume injected was 147.8 mL per breast (22-564 mL). The average ratio of fat injected to initial flap weight was 0.59 (0.07-1.39). Patients undergoing fat grafting were more likely to have had deep inferior epigastric perforator and profunda artery perforator flaps as compared to muscle-sparing transverse rectus abdominis myocutaneous. Patients additionally were more likely to have a prophylactic indication 58% (n = 58) versus 42% (n = 117) (P = 0.0087), rib resection 68% (n = 68) versus 54% (n = 148) (P < 0.0153), and acute postoperative complications requiring operative intervention 7% (n = 7) versus 2.1% (n = 8) (P < 0.0480). Additionally, patients undergoing autologous fat grafting had smaller body mass index, mastectomy weight, and flap weight. CONCLUSIONS: Fat grafting is most commonly used in those breasts with rib harvest, deep inferior epigastric perforator flap reconstructions, and those with acute postoperative complications. It should be considered a powerful adjunct to improve aesthetic outcomes in volume-deficient autologous breast reconstructions and additionally optimize contour in volume-adequate breast reconstructions.

PURPOSE: There is no more important decision an academic Plastic Surgery Department or Division can make than naming a chair or chief. Externally recruited leadership brings fresh perspectives and connections. Critics, however, argue that they lack the in-depth knowledge of the institution's culture and history that may be needed to succeed. The ability and skill of an internal candidate is already known and can increase the odds of that person's success in the leadership position. Finally, external recruitment can be a more costly process. Ultimately, the decision is really a litmus test for a Plastic Surgery program. The authors aim to evaluate factors influencing ascent in Plastic Surgery leadership, including training history, internal promotion, and external recruiting. METHODS: All Plastic Surgery residency programs accredited by the Accreditation Council for Graduate Medical Education were noted (n = 71). Academic departmental chairs or divisional chiefs of these residency programs were identified at the time of study design (October 1, 2011). For each chair or chief, gender, training history, and faculty appointment immediately prior to the current leadership position was recorded. RESULTS: There were 71 academic chairs or chiefs of Plastic Surgery residency programs at the time of data collection. The majority (62%) had done fellowship training following Plastic Surgery residency. Fellowships included hand (43%), craniofacial (29%), microsurgery (18%), and other types (10%). The majority (73%) of leaders were internal hires (P < 0.01), having faculty appointments at their institutions prior to promotion. However, only a fraction (22%) of these internal hires had done Plastic Surgery residency or fellowship training at that institution (P < 0.01). External recruits consisted of 27% of all 71 academic hires (P < 0.01). CONCLUSIONS: Many factors influence the decision to recruit leadership from internally or to hire an external candidate. These include the time to fill the position, program culture, candidate experience, and cost. These results support that the insider/outsider hire decision is ultimately one of duality. That dichotomy is achieved with an emphasis on internal promotion, but always with an eye towards the advantages of bringing in external talent as a valuable contribution to increase organizational success.

BACKGROUND: : Tumors of the mandible are complex, often requiring replacement of bone, soft tissue, and teeth. The fibula flap has become a routine procedure in large tumors of the jaw, providing bone and soft tissue at the time of the resection. In current practice, dental reconstruction is delayed for 3 to 6 months, leaving the patient without teeth in the interim. This can be disfiguring and anxiety provoking for the patient. METHODS: : In this article, the authors present three patients with benign tumors of the mandible who underwent virtually guided resection, fibula reconstruction, and insertion of an implant-retained dental prosthesis in one operation. In addition, the authors report their early experience using this technique in the maxilla. RESULTS: : The authors present a case series of three patients with benign mandibular tumors and one patient with a benign maxillary tumor who underwent total reconstruction using computer-aided design and computer-aided manufacturing technology in a single stage. CONCLUSIONS: : In the right situation, total mandibular reconstruction is possible in a single stage. This is demonstrated by the successful outcomes of these patients.
