BACKGROUND: Inferior turbinate hypertrophy is often encountered by plastic surgeons who perform rhinoplasty. Many treatment options are available to treat the inferior turbinate. The objective of this study was to systematically review outcomes of available techniques and provide guidance to surgical turbinate management. METHODS: A MEDLINE search was performed for means of treating inferior turbinate hypertrophy. Studies selected focused on treatment of the inferior turbinate in isolation and excluding patients with refractory allergic rhinitis, vasomotor rhinitis, or hypertrophic rhinitis. RESULTS: Fifty-eight articles were identified, collectively including the following surgical treatments of inferior turbinate hypertrophy: total turbinectomy, partial turbinectomy, submucosal resection, laser surgery, cryotherapy, electrocautery, radiofrequency ablation, and turbinate outfracture. Outcomes and complications were collected from all studies. Procedures such as turbinectomy (partial/total) and submucosal resection showed crusting and epistaxis at comparatively higher rates, whereas more conservative treatments such as cryotherapy and submucous diathermy failed to provide long-term results. Submucosal resection and radiofrequency ablation were shown to decrease nasal resistance and preserve mucosal function. No literature exists to support the belief that turbinate outfracture alone is an effective treatment for turbinate hypertrophy. CONCLUSIONS: Treatment of inferior turbinate hypertrophy is best accomplished with modalities that provide long-lasting results, preservation of turbinate function, and low complication rates. Submucosal resection and radiofrequency ablation appear to best fulfill these criteria. Turbinate outfracture should only be considered in combination with tissue-reduction procedures.

BACKGROUND: Reconstruction of extensive facial and scalp burns can be increasingly challenging, especially in patients that have undergone multiple procedures with less than ideal outcomes resulting in restricting neck and oral contractures, eyelid dysfunction, and suboptimal aesthetic appearance. METHODS: To establish a reconstructive solution for this challenging deformity, a multidisciplinary team was assembled to develop the foundation to a facial vascularized composite allotransplantation program. The strategy of developing and executing a clinical transplant was derived on the basis of fostering a cohesive and supportive institutional clinical environment, implementing computer software and advanced technology, establishing a cadaveric transplant model, performing a research facial procurement, and selecting an optimal candidate with the aforementioned burn defect who was well informed and had the desire to undergo face transplantation. RESULTS: Approval from the institutional review board and organ procurement organization enabled our face transplant team to successfully perform a total face, eyelids, ears, scalp, and skeletal subunit transplant in a 41-year-old man with a full face and total scalp burn. CONCLUSIONS: The culmination of knowledge attained from previous experiences continues to influence the progression of facial vascularized composite allotransplantation. This surgical endeavor methodically and effectively synchronized the fundamental principles of aesthetic, craniofacial, and microvascular surgery to restore appearance and function to a patient suffering from failed conventional surgery for full face and total scalp burns. This procedure represents the most extensive soft-tissue clinical face transplant performed to date. CLINICAL QUESTION/LEVEL OF EVIDEMCE: Therapeutic, V.

Computer assisted modeling (CAM) has become an important tool in surgical oncology and reconstructive surgery. The preservation of the limb is an important consideration when approaching the treatment of lower extremity and pelvic tumors. The use of cutting guides allows for optimal conservation of disease-free bone and maintenance of function. We present a small case series that illustrates the use of CAM in patients with lower extremity and pelvic bone tumors.

BACKGROUND: Venous outflow problems are the most common reasons for perioperative flap complications. The benefit of a second venous anastomosis, however, remains unclear in lower extremity trauma free flap reconstruction and warrants further investigation. MATERIALS AND METHODS: Retrospective review of our institutional flap registry from 1979 to 2014 identified 464 free flaps performed for lower leg trauma reconstruction. Patient demographics, flap characteristics, and outcomes were examined. RESULTS: A total of 219 flaps were randomly selected for preliminary analysis. Single-vein outflow was more common (72.6%) than dual-vein (27.4%); most of the recipients were in deep venous system (83.6%) versus superficial (11.9%) or both (4.6%). Two-vein anastomoses were more likely in fasciocutaneous flaps than muscle flaps (P = 0.001) and in smaller (<300 cm(2)) flaps (P = 0.002). Complications occurred in 98 flaps (44.7%); with 54 partial flap losses (24.7%), and 11 complete flap losses (5.0%). Multivariable regression analysis controlling for age, sex, flap type, presence of bone gap, flap size, vein size mismatch, and time since injury demonstrated dual-vein outflow to be protective against complications (relative risk [RR] = 0.269, P = 0.001), partial flap failure (RR = 0.351, P = 0.031), and any flap failure (RR = 0.31, P = 0.010). No significant difference in operative time was found (P = 0.664). CONCLUSIONS: Dual-vein outflow demonstrated 73% reduction in overall complications and 69% reduction in flap failure rate compared to single-vein flaps. These results suggest a protective effect of a dual-vein outflow system, and when considered together with our findings of unchanged operative time, provide evidence for preferential use of two venous anastomoses when possible for free flap reconstruction of lower extremity trauma.

BACKGROUND: The application of aesthetic, craniofacial, and microsurgical principles in the execution of face transplantation may improve outcomes. Optimal soft-tissue face transplantation can be achieved by incorporating subunit facial skeletal replacement and subsequent tissue resuspension. The purpose of this study was to establish a reconstructive solution for a full face and scalp burn and to evaluate outcome precision and consistency. METHODS: Seven mock face transplants (14 cadavers) were completed in the span of 1 year. Components of the vascularized composite allograft included the eyelids, nose, lips, facial muscles, oral mucosa, total scalp, and ears; and skeletal subunits of the zygoma, nasal bone, and genial segment. Virtual surgical planning was used for osteotomy selection, and to evaluate postoperative precision of hard- and soft-tissue elements. RESULTS: Each transplant experience decreased each subsequent transplant surgical time. Prefabricated cutting guides facilitated a faster dissection of both donor and recipient tissue, requiring minimal alteration to the allograft for proper fixation of bony segments during inset. Regardless of donor-to-recipient size discrepancy, ample soft tissue was available to achieve tension-free allograft inset. Differences between virtual transplant simulation and posttransplant measurements were minimal or insignificant, supporting replicable and precise outcomes. CONCLUSIONS: This facial transplant model was designed to optimize reconstruction of extensive soft-tissue defects of the craniofacial region representative of electrical, thermal, and chemical burns, by incorporating skeletal subunits within the allograft. The implementation of aesthetic, craniofacial, and microsurgical principles and computer-assisted technology improves surgical precision, decreases operative time, and may optimize function.

BACKGROUND: Systematic reporting of mortality data is lacking in many surgical fields including plastic surgery. Current plastic surgery literature is largely limited to adverse events associated with specific procedures. Without mortality data, it is unclear how the recent growth of patient safety initiatives can rationally impact outcomes. METHODS: We evaluated 11 years of patient outcome data collected prospectively and updated monthly by our department. Paper records were entered into a Health Insurance Portability and Accountability Act-compliant digital database capable of prospectively maintaining future data. Data were reviewed for 5 surgical services in 4 different hospitals that comprise our department's activity. RESULTS: Between 2000 and 2011, a total of 60,834 cases were performed. In this time, a total of 829 (1.4%) negative outcome reports were identified. Of these, a total of 25 (0.04%) cases had an outcome of death (24) or brain death (1). Deaths were either directly or indirectly associated with cardiopulmonary causes, multisystem organ failure, sepsis, massive bleeding, CVA, saddle embolism, or unknown causes. CONCLUSIONS: This study is the largest reported series of cases performed by a single academic plastic surgery service to report overall mortality data.

BACKGROUND: Cadaveric face transplant models are routinely used for technical allograft design, perfusion assessment, and transplant simulation but are associated with substantial limitations. The purpose of this study was to describe the experience of implementing a translational donor research facial procurement and solid organ allograft recovery model. METHODS: Institutional review board approval was obtained, and a 49-year-old, brain-dead donor was identified for facial vascularized composite allograft research procurement. The family generously consented to donation of solid organs and the total face, eyelids, ears, scalp, and skeletal subunit allograft. RESULTS: The successful sequence of computed tomographic scanning, fabrication and postprocessing of patient-specific cutting guides, tracheostomy placement, preoperative fluorescent angiography, silicone mask facial impression, donor facial allograft recovery, postprocurement fluorescent angiography, and successful recovery of kidneys and liver occurred without any donor instability. Preservation of the bilateral external carotid arteries, facial arteries, occipital arteries, and bilateral thyrolinguofacial and internal jugular veins provided reliable and robust perfusion to the entirety of the allograft. Total time of facial procurement was 10 hours 57 minutes. CONCLUSIONS: Essential to clinical face transplant outcomes is the preparedness of the institution, multidisciplinary face transplant team, organ procurement organization, and solid organ transplant colleagues. A translational facial research procurement and solid organ recovery model serves as an educational experience to modify processes and address procedural, anatomical, and logistical concerns for institutions developing a clinical face transplantation program. This methodical approach best simulates the stressors and challenges that can be expected during clinical face transplantation. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

BACKGROUND: Augmentation gluteoplasty has been performed more frequently in the past decade, with over 21,000 procedures performed in the past year alone. The most popular methods for buttock augmentation involve silicone prostheses and autologous fat grafting. A comparison of complications of these two techniques does not exist in our literature. METHODS: The PubMed, MEDLINE, and Cochrane databases were searched through April of 2015 for studies that achieved buttock augmentation through the use of silicone implant placement or autologous lipoinjection. Complication outcomes of interest included wound dehiscence, infection, seroma, hematoma, asymmetry, and capsular contracture. RESULTS: Forty-four articles met inclusion criteria. The most commonly reported complications in 2375 patients receiving silicone implants were wound dehiscence (9.6 percent), seroma (4.6 percent), infection (1.9 percent), and transient sciatic paresthesias (1.0 percent), with an overall complication rate of 21.6 percent (n = 512). The most commonly reported complications in 3567 patients receiving autologous fat injection were seroma (3.5 percent), undercorrection (2.2 percent), infection (2.0 percent), and pain or sciatalgia (1.7 percent), with an overall complication rate of 9.9 percent (n = 353). Patient satisfaction after surgery was assessed differently among studies and could not be compared quantitatively. CONCLUSIONS: Although gluteal augmentation was once reported to have complication rates as high as 38.1 percent, a systematic review of the two most popular techniques demonstrated substantially lower overall complication rates. The overall complication rate with autologous fat grafting (9.9 percent) is lower than that with silicone buttock implants (21.6 percent). A standardized method of measuring patient satisfaction is necessary to fully understand outcomes of these increasingly popular procedures.

BACKGROUND: Virtual surgical planning (VSP) has contributed to a number of technical innovations in mandible reconstruction. We report on these innovations and the overall evolution of mandible reconstruction using free fibula flaps at our institution. METHODS: We performed a retrospective chart review of all patients who underwent virtually planned free fibula flap reconstruction of the mandible. Comparisons were made between cohorts based on distinct eras related to the virtual planning approach. RESULTS: Seventy-six patients underwent a total of 78 VSP-assisted mandible reconstructions with free fibula flaps. Significant differences were noted among the groups with regard to mean number of segments, percentage of flaps that had at least 3 segments, percentage of flaps that had double-barrel components, and innovations per flap. CONCLUSION: VSP-assisted mandible reconstruction has contributed to more complex surgeries at our institution. The technology ensures functional restoration, permitting an optimized aesthetic reconstruction that has not increased operative times or complications. (c) 2016 Wiley Periodicals, Inc.
