Cross-linking improved amnion durability. Photochemically bonded cross-linked amnion recovered the greatest sciatic function index, although this was not significant in comparison with graft and suture. Photochemically bonded cross-linked amnion recovered significantly greater muscle mass (67.3 ± 4.4 percent versus 60.0 ± 5.2 percent; p = 0.02), fiber diameter, axon diameter, and myelin thickness (6.87 ± 2.23 μm versus 5.47 ± 1.70 μm; 4.51 ± 1.83 μm versus 3.50 ± 1.44 μm; and 2.35 ± 0.64 μm versus 1.96 ± 0.47 μm, respectively) in comparison with graft and suture.

Light-activated sealing of cross-linked human amnion results in superior outcomes when compared with conventional suture.

Abdominal wall vascularized composite allotransplantation is the second most common form of vascularized composite allotransplantation. Sensory and functional recovery are expected in other forms but have never been demonstrated in abdominal wall vascularized composite allotransplantation. The authors hypothesize that coaptation of two thoracolumbar nerves will result in reinnervation of the alloflap and maintenance of the muscle component.

Adult, male, 10-week-old Brown Norway and Lewis rats were used for experiments. The rat donor's common iliac vessels were anastomosed to the recipient's femoral vessels. Intercostal nerves T10/L1 were coapted. Four groups (n = 5 per group) were included for study group 1, Lewis, intercostal nerves cut, not repaired; group 2, Lewis intercostal nerves cut, T10/L1 repaired; group 3, allogeneic Brown Norway-to-Lewis abdominal wall vascularized composite allotransplantation, T10/L1 repaired; and group 4, syngeneic Lewis-to-Lewis abdominal wall vascularized composite allotracomponent.

In a murine model for abdominal wall vascularized composite allotransplantation, coaptation of T10/L1 will allow for reinnervation of the alloflap and maintenance of the muscle component.

The use of autologous adipose tissue harvested through liposuction techniques for soft-tissue augmentation has become commonplace among cosmetic and reconstructive surgeons alike. Despite its longstanding use in the plastic surgery community, substantial controversy remains regarding the optimal method of processing harvested lipoaspirate before grafting. This evidence-based review builds on prior examinations of the literature to evaluate both established and novel methods for lipoaspirate processing.

A comprehensive, systematic review of the literature was conducted using Ovid MEDLINE in January of 2015 to identify all relevant publications subsequent to the most recent review on this topic. Randomized controlled trials, clinical trials, and comparative studies comparing at least two of the following techniques were included decanting, cotton gauze (Telfa) rolling, centrifugation, washing, filtration, and stromal vascular fraction isolation.

Nine articles comparing various methods of processing human or autologous fat grafting. A paucity of high-quality data continues to limit the clinician's ability to determine the optimal method for purifying harvested adipose tissue. Novel automated technologies hold promise, particularly for large-volume fat grafting; however, extensive additional research is required to understand their true utility and efficiency in clinical settings.

Medium to large septal perforations are a challenging problem to the rhinoplasty surgeon. In this study, records and outcomes are reviewed for 25 patients who underwent septal perforation repair over a 10-year period. All patients underwent an open septorhinoplasty approach with use of bilateral opposing mucoperichondrial flaps and a unique intervening graft that included acellular dermis, temporalis fascia alone, or a novel closure technique using temporalis fascia and a polydioxanone plate. The authors identify that for medium to large septal perforations, the use of the polydioxanone plate with temporalis fascia provided the highest rate of closure as a method of scaffolding a fascial graft, and also provided ease of placement between opposing mucoperichondrial flaps.

Capsular contracture is common and distressing after aesthetic breast augmentation. The precise cause of capsular contracture is not well established. This systematic review investigates current available evidence regarding perioperative povidone-iodine irrigation safety and efficacy in reducing capsular contracture.

PubMed/MEDLINE, Embase, and Scopus databases were searched for publications through December of 2014. Studies with the following criteria were included (1) primary breast augmentation with implants; (2) perioperative povidone-iodine use; and (3) documentation of capsular contracture. Our primary outcome was incidence of Baker class III/IV capsular contracture. The methodologic quality of included studies was assessed independently. Trials were meta-analyzed to obtain a pooled odds ratio describing the effect of povidone-iodine irrigation on Baker class III/IV capsular contracture.

Nine studies with a total of 5153 patients undergoing aesthetic breast augmentation with implants were included. Only three comparative studies achieved high methodologic quality. The meta-analysis included four studies, with 1191 patients receiving povidone-iodine irrigation and 595 patients receiving saline irrigation. The meta-analysis favored povidone-iodine irrigation for decreasing Baker class III/IV capsular contracture (2.7 percent versus 8.9 percent; OR, 0.30; 95 percent CI, 0.18 to 0.50; p < 0.00001; I = 0 percent). The reported implant rupture rates for both saline implants and silicone implants were less than 1 percent.

Perioperative povidone-iodine irrigation reduces Baker class III/IV capsular contracture and is not associated with implant rupture. Low methodologic quality of included studies limits recommendations for perioperative povidone-iodine irrigation as the standard of practice. Additional high-quality trials are warranted to corroborate the findings of this meta-analysis.

Biophysical characteristics of hyaluronic acid gel fillers reflect individual manufacturing processes. They confer rheologic properties that provide scientific rationale with Evidence Level II clinical correlation for selection of appropriate fillers for specific clinical applications. Cohesivity, a key property, maintains gel integrity, contributes to tissue support with natural contours, and diminishes surface irregularities. In this publication, a new, standardized visual assay for hyaluronic acid cohesivity is presented, applied, and discussed.

Colored hyaluronic acid gel specimens were automatically extruded under standardized conditions into sterile water stirred at a constant rate. Based on 90 digital images showing ratios of intact to dispersed gel during assay of 10 Communauté Européenne-marked fillers, the five-point visual Gavard-Sundaram Cohesivity Scale was developed. Six plastic surgeons and dermatologists performed pilot validation of the scale, subsequently used to evaluate six U.S. Food and Drug Administration-approved fillers.

Validation of the Gavard-Sundaram Cohesivity Scale showed substantial repeatability and interrater consistency. Mean cohesivity scores from three assays of each tested filler showed significant differences. Cohesivity was high for Cohesive Polydensified Matrix (Belotero Balance), medium-high for Hylacross (Juvéderm Ultra 2/Ultra XC and Ultra 3/Ultra Plus XC), low-medium for Vycross (Juvéderm Voluma), and low for non-animal-stabilized hyaluronic acid (Restylane and Perlane).

An evidence-based approach requires clinical corroboration of in vitro data. This new, reproducible cohesivity assay may have value together with elasticity (G') and viscosity measurements to understand and leverage distinct tissue distribution patterns and clinical behaviors of different hyaluronic acid products.

As bundled payment models gain popularity, it is imperative that providers use patient outcomes and patient experience to define evidence-based pathways of care. The purpose of this study was to evaluate the quality of recovery experienced by women undergoing early discharge (<24 hours) after autologous breast reconstruction with a pedicled flap and determine predictors of postoperative quality of recovery.

A prospective cohort study was performed on all women undergoing autologous breast reconstruction at Women's College Hospital between September of 2011 and July of 2013 that met study inclusion criteria. The patient-reported Quality of Recovery-27 questionnaire was used to measure quality of recovery on postoperative days 1, 2, 4, and 7. Preoperative and postoperative day 7 Quality of Recovery-27 questionnaire scores were compared. A multivariable random effect model for longitudinal data was used to evaluate any relationship between postoperative Quality of Recovery-27 questionnaire scores and American Society of Anesthesiologists classification, body mass index, and pain. Secondary analyses of delayed discharge (>24 hours) and complications were also undertaken.

Forty women, aged 28 to 69 years, were included in this study. There was no statistically significant difference between the preoperative and postoperative day 7 Quality of Recovery-27 questionnaire scores, suggesting that our patients recovery to their preoperative state by postoperative day 7. Poorer total Quality of Recovery-27 questionnaire scores were associated with higher American Society of Anesthesiologists classification, low and high body mass indexes (U-shaped relationship), and higher pain scores.

Patients undergoing an ambulatory pathway of care for autologous breast reconstruction demonstrate acceptable quality of recovery.

AlloDerm and FlexHD are two types of acellular dermal matrices commonly used in implant-based reconstruction. Although the use of acellular dermal matrix has revolutionized immediate breast reconstruction in the setting of breast cancer, it remains unclear which type of acellular dermal matrix is best. The purpose of this retrospective cohort study was to compare postoperative complication rates between these two types of acellular dermal matrix.

The authors reviewed the records of all patients who underwent implant-based breast reconstruction at their institution between 1998 and 2013. A-1155463 Dependent variables of seroma, hematoma, infection, delayed wound healing, implant exposure, and return to the operating room for management of complications were recorded.

A total of 309 consecutive patients were identified. Of these, AlloDerm was used in 123 patients (39.8 percent) and FlexHD was used in 186 patients (60.2 percent). Most patients in the authors' cohort underwent immediate reconstruction [n = 288 (93.2 percent)], with a mean follow-up of 20.0 months. Patients receiving AlloDerm were half as likely to have major infections compared with patients receiving FlexHD (OR, 0.50; 95 percent CI, 0.16 to 1.00; p < 0.05). The rates of other complications were similar between the two groups.

There are significantly increased odds of a major infection in patients who undergo implant-based breast reconstruction using FlexHD compared with AlloDerm.
