RESUMO
BACKGROUND: Control of nasal tip position is critical to final rhinoplasty outcomes. Two frequent methods of exerting tip control are columellar strut and caudal septal extension graft (SEG). Past work has demonstrated that SEG are better able to preserve tip position. However, there is no quantitative data describing long-term projection and rotation. The purpose of this study was to analyze long-term maintenance of tip projection and rotation following SEG. METHODS: A retrospective study of adult patients undergoing open rhinoplasty was conducted. Three-dimensional photogrammetric evaluation of nasal tip position was performed. Anthropometric points were analyzed preoperatively and postoperatively. Outcome variables were tip projection, tip rotation, and nasal length. RESULTS: Twenty patients were included with an average follow-up time of 3.3 years (2.0 - 6.6 years). From postoperative week 1 to 6, there was a statistically significant decrease in rotation (-4.3%, p<0.01). There were no statistically significant decreases in projection, rotation, or nasal length from 6 weeks postoperative to 2 years postoperative, or from 6 weeks postoperative to final follow-up (2.0 - 6.6 years). CONCLUSIONS: Nasal tip projection and rotation appear to decrease from the immediate postoperative position, likely due to resolving edema. In this study, patients that underwent open rhinoplasty with SEG experienced modest loss of projection and rotation until 6 weeks postoperative, but projection and rotation were maintained from 6 weeks postoperative to 2 years and beyond. This study provides evidence that SEG maintains long-term changes in tip projection and rotation. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

BACKGROUND: Reconstruction of facial melanoma defects can be challenging. Large defects of the midface, cheek, and nasolabial fold are often reconstructed using a cervicofacial flap which requires significant flap elevation and undermining. Surgeons are often hesitant to commit to such a large reconstruction without definitive pathologic evidence of negative margins. However, local perforator flaps may be used as an alternative to large flaps with less dissection and donor site morbidity and may also allow for more facile re-advancement in the event of a positive margin on final pathology. The goal of this study is to evaluate a perforator flap based on the facial artery to determine if it is a safe and cosmetically favorable option to immediately repair oncologic-related defects on the cheek and midface. METHODS: A retrospective review of all melanoma cases performed by the senior author between January 2016 and December 2021 was conducted. Patients who underwent reconstruction using a facial artery perforator flap were included. RESULTS: Sixteen patients were included in our cohort. The average age was 67.3 years and 53% (n=8) were female. Fourteen patients had the primary defect located on the cheek, 1 from the nasolabial fold, and 1 from the distal nasal sidewall. All patients received immediate reconstruction. Excisional margins ranged from 0.5 to 2 cm. Two patients had positive margins following pathology results with one undergoing treatment with imiquimod and the other opting for re-excision. No complications involving the defect or donor site were reported after an average follow-up time of 113.8 days. CONCLUSION: The facial artery perforator flap is a safe and cosmetically favorable option to immediately repair oncologic-related defects on the cheek and midface.

Spreader grafts traditionally are used to improve airflow through opening the internal nasal valve, as well as enhance the cosmetic appearance of the nose. The graft's versatility proves useful in surgical correction of several nasal profiles by enhancing dorsal aesthetic lines and by maintenance of the nasal pyramid at midline. The authors describe a modified spreader graft that adds an additional benefit of dorsal augmentation in patients with underprojected or saddle noses. This technique utilizes harvested septal cartilage and fixation of the graft that extends beyond the septal and upper lateral cartilage dorsal border to improve nasal dorsum height. Patients who received this operative technique by the senior author were identified and their operative courses and surgical outcomes were analyzed. Case examples are provided to illustrate indications and outcomes. This grafting technique allows for improved functionality, defined dorsal aesthetic lines, changes in nasal width, and a more balanced profile in patients with underprojected noses.

BACKGROUND: There has been increasing interest in the superficial circumflex iliac artery perforator (SCIP) flap as a source of thin, pliable soft tissue combined with a favorable donor site. Despite several clinical series from Asia, barriers to adoption include reluctance to perform submillimeter "supermicrosurgery" and the effect of body habitus on flap feasibility. The purpose of this study is to distinguish vascular anatomic characteristics of the SCIP flap in a North American population. METHODS: Computed tomography angiography was examined in 84 flaps in healthy prospective renal donor patients from a radiographic database. Descriptive statistics as well as linear regression comparing variables to body mass index (BMI) were performed. RESULTS: Mean BMI was 27.1 ± 3.5 kg/m2, while the mean patient age was 47.8 ± 11.4 years. The superficial circumflex iliac artery (SCIA) originated from the common femoral artery in 92% cases, with remainder originating from the profunda femoris. The mean vessel diameter was 1.85 mm at source vessel origin. Distance from skin to source vessel averaged 30.7 mm. Suprascarpal subcutaneous thickness averaged 16.5 mm. The mean distance from Scarpa's fascia to vessel origin was 14.1 mm. Direct three-dimensional distance from vessel origin to pubic tubercle was 50.2 mm. A medial and lateral perforator split off of the SCIA was observed in 38 cases (45%). Significant differences were shown when comparing BMI to skin to source vessel distance (p < 0.001), suprascarpal subcutaneous fat thickness (p < 0.001), and fascial distance to vessel origin (p < 0.001). BMI did not significantly affect vessel diameter. CONCLUSION: Despite a significantly higher BMI than many previously published cohorts, the SCIP remains an excellent source of thin and pliable tissue. When dissected closer to the source vessel, a vessel caliber of nearly 2 mm can be achieved, which may obviate the need for "supermicrosurgery" in this population.

BACKGROUND: The need for preoperative imaging as well as anastomotic technique (ie, end-to-side [ETS] vs end-to-end [ETE]) are areas of controversy in microsurgical lower-extremity reconstruction. The objective of this study was to (1) investigate whether preoperative imaging is mandatory and (2) to elicit if the type of anastomosis impacts clinical outcomes. METHODS: A retrospective review of all patients who underwent microvascular lower-extremity reconstruction between 2007 and 2015 by a single surgeon was performed. Patients were categorized into groups based on anastomotic technique, that is, ETE versus ETS anastomosis. Patients in the ETE group were further subclassified into those who had preoperative imaging (computed tomography angiography [CTA]+) versus those who did not (CTA-). Parameters of interest included flap type, thrombosis rate, flap loss, length of stay (LOS), return to ambulation, and rate of secondary amputation. Two-sided statistical analysis was performed using Kruskal-Wallis rank-sum test and Fisher exact test. RESULTS: One hundred twenty-eight patients were analyzed: ETE (n = 40) and ETS (n = 88). Mean follow-up for both groups was 20 ± 19 months. Anterolateral thigh flaps were most commonly performed (71%). Overall flap loss rate was 3.1% without any significant differences noted with respect to thrombosis (arterial, P = 0.09; venous, P = 0.56), flap loss (P = 0.33), LOS (P = 0.28), amputation (P = 1.00), or return to ambulation (P = 0.77). Furthermore, the availability of preoperative imaging (CTA+: N = 11 vs CTA-: N = 29) did not impact rates of thrombosis (arterial, P = 0.29; venous, P = 0.31), flap loss (P = 1.00), LOS (P = 0.26), or return to mobility (P = 0.62). CONCLUSIONS: In light of similar reconstructive outcomes, we prefer to preserve distal extremity perfusion via ETS anastomoses whenever possible. Furthermore, preoperative vascular imaging angiography might not be necessary in patients with palpable pedal pulses on preoperative examination. An actionable algorithm for determining ETS versus ETE anastomosis in lower-extremity reconstruction is presented.

BACKGROUND: Prophylactic mesh placement (PMP) at the time of open abdominal surgery has gained momentum over the last decade. However, there remains an identifiable gap in the literature regarding patient-reported outcomes and qualitative metrics. In effort to gauge the population's understanding or familiarity with PMP, this study provides an educational framework and uses crowdsourcing as a novel means to assess perception among the general population. METHODS: A cross-sectional survey study was conducted among the general public to elicit perspectives on PMP. An online crowdsourcing platform was used to capture responses to a questionnaire. Pearson's correlation coefficients, paired t-test, chi-square test, and Fisher's exact tests were performed. RESULTS: Of 433 respondents, 338 (78.1%) were included. Individuals who had previously undergone surgery and those who had prior hernia repair were more likely to choose PMP than surgically naïve patients (P = 0.06). CONCLUSIONS: The majority of respondents support the use of PMP. This study contributes to the existing body of literature on PMP and serves as the first qualitative description to gauge the population's perception and understanding of this surgical technique. Within the evolving health care landscape, understanding quality-of-life measures have become increasingly important in defining successful surgical outcomes. Although the data-driven level-I evidence supports the clinical use of PMP, this study intends to establish a framework for future patient-reported outcome studies.

BACKGROUND: Color Doppler ultrasound (CDUS) has not been routinely used in plastic and reconstructive surgery. Barriers to use have included large, cumbersome equipment, low-definition images, cost, and availability. In addition, programs in plastic surgery have not included training with ultrasound (US); thus, many current-day practitioners are unfamiliar with and reluctant to use this technology. Nevertheless, recent studies have demonstrated the utility of US in surgical planning. With the miniaturization, clearer imaging, and decreased costs of the latest US technology, previous barriers to use have largely been eliminated. METHODS: Fifty-six patients scheduled for either reconstructive or aesthetic surgery were evaluated preoperatively and/or intraoperatively by a single surgeon with the linear 12-4 probe of a Philips Lumify CDUS device (Philips, Reedsville, Penn). For patients undergoing flap reconstruction, potential donor sites were imaged in order to locate the largest perforator. For patients undergoing abdominal procedures, intraoperative visualization of the abdominal muscular layers was used for the delivery of anesthesia during transversus abdominis plane block. Lastly, the superficial fascial system (SFS) was subjectively evaluated in all preoperative patients. RESULTS: For flap reconstruction, 11 patients were preoperatively examined with CDUS in order to locate the largest perforators prior to perforator flap reconstruction. Flaps studied included the deep inferior epigastric perforator, anterolateral thigh, tensor fascia lata, thoracodorsal artery perforator, superior gluteal artery perforator, and the gracilis musculocutaneous. Color Doppler ultrasound findings were confirmed intraoperatively for all cases (100%). In 2 (18.2%) of 11 cases, CDUS identified perforators not detected by computed tomography angiography. Twenty-five patients undergoing either abdominoplasty or deep inferior epigastric perforator flap reconstruction had successful intraoperative visualization of the abdominal wall muscular layers, thus allowing administration of transversus abdominis plane blocks by the operating surgeon. Twenty patients undergoing body contouring surgery had preoperative visualization of the SFS. The SFS was found to be varied not only among different patients but also within individual patients. CONCLUSIONS: The newest, miniaturized CDUS technology has a variety of applications that may improve patient outcomes and experience in plastic surgery. Our observations require further investigation to quantify the perceived benefits of this new technology.

BACKGROUND: Mesh infection after abdominal hernia repair is a devastating complication that affects general and plastic surgeons alike. The purpose of this study was 3-fold: (1) to determine current evidence for treatment of infected abdominal wall mesh via systematic review of literature, (2) to analyze our single-institution experience with treatment of infected mesh patients, and (3) to establish a framework for how to approach this complex clinical problem. METHODS: Literature search was performed using the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, followed by single-institution retrospective analysis of infected mesh patients. RESULTS: A total of 3565 abstracts and 92 full-text articles were reviewed. For qualitative and quantitative assessment, articles were subdivided on the basis of treatment approach: "conservative management," "excision of mesh with primary closure," "single-stage reconstruction," "immediate staged repair," and "repair in contaminated field." Evidence for each treatment approach is presented. At our institution, most patients (40/43) were treated by excision of infected mesh and single-stage reconstruction with biologic mesh. When the mesh was placed in a retrorectus or underlay fashion, 21.4% rate of hernia recurrence was achieved. Bridged repairs were highly prone to recurrence (88.9%; P = 0.001), but the bridging biologic mesh seemed to maintain domain and potentially contribute to a more effective repair in the future. Of the patients who underwent additional ("secondary") repairs after recurrence, 75% were eventually able to achieve "hernia-free" state. CONCLUSIONS: This study reviews the literature and our single-institution experience regarding treatment of infected abdominal wall mesh. Framework is developed for how to approach this complex clinical problem.

INTRODUCTION: The medial thighplasty is a procedure where patients may attain superior mobility, hygiene, and cosmesis. Most surgeons use attachment of the superficial fascial system (SFS) of the thigh flap to the Colles fascia, whereas others attach the SFS to the pubic ramus periosteum. Because of a high complication profile, we aim to elucidate the clinical, biomechanical, and anatomic qualities of the Colles fascia versus the pubic ramus periosteum. MATERIALS AND METHODS: We performed a 17-year retrospective review documenting clinical complications, a biomechanical analysis of sutures placed in different tissue layers of the thigh, and a histologic analysis surrounding the ischiopubic ramus. Separate suture pull-out strength testing was conducted on cadaveric tissue using an Admet MTEST Quattro with no. 1 Vicryl suture and tissue grips at a displacement rate of 2.12 mm/s. Simultaneous displacement and force were acquired at 100 Hz and with measurements obtained at regular intervals between the pubic symphysis and the ischial tuberosity in both the Colles fascia and the deeper periosteal layers of the thigh. A histologic analysis was performed at 3 points along the ischiopubic ramus using paraffin-embedded large mount tissue sections stained with hematoxylin, eosin, and Gomori trichrome. RESULTS: Thirty-nine patients underwent medial thighplasty with a 46.16% complication rate. Suture pull-out force of the suspected superficial Colles fascia sites was, on average, 72.8% less than values from the deeper periosteum tissue. Anchor points in the Colles fascia elongated 17.4% further before failure than those in the periosteum. There was noticeable variability between anchor points and across samples. The histologic sections suggest that the Colles fascia from the different regions of the ischiopubic ramus varies considerably in both continuity and collagen fiber content with no discernible pattern. The periosteal and muscular fascial layers were more continuous histologically with direct attachments into the pubis and ischium. CONCLUSIONS: Anchoring of the SFS to the periosteum did not improve our complication profile when compared with the literature. Both the biomechanical and histologic analyses demonstrate that the Colles fascia is highly variable in organizations with coincident variability in tissue strength. Our results require further study to identify the optimal surgical technique for medial thighplasty.

BACKGROUND: Congenital lipomatous overgrowth, vascular malformations, epidermal nevi, and skeletal abnormalities (CLOVES) is a complex overgrowth syndrome with dramatic aesthetic and functional implications. The truncal masses characteristic of CLOVES syndrome are described as vascular malformations or lipomatous lesions with variable vascular components. Herein, we describe our single-institution experience with surgical excision of CLOVES-related truncal masses and discuss future directions in treatment of these complex anomalies. METHODS: A single-institution retrospective review was performed for patients diagnosed with CLOVES syndrome. Patients undergoing excision of truncal vascular malformations were included. Outcome measures included perioperative characteristics [estimated blood loss (EBL), specimen size/anatomic location, blood-product requirement], as well as length-of-stay [LOS], and complication profile. Mean follow-up was 23.4 months (range 4.2-44). RESULTS: Three consecutive patients were reviewed, accounting for 4 surgical operations. One patient underwent two operations for two distinct masses. All lesions were located on the upper back or flank with various degrees of muscular involvement. One patient required no transfusions with an uneventful 2-day hospitalization. The remaining three patients had an EBL ranging from 1500 to 6450 mL, requiring 9-13 units of packed red blood cells and 5-8 units of fresh frozen plasma during LOS (averaging 5 days). Mean weight of resected masses was 6.26 lbs (range 2.04-12 lbs) and mass dimensions ranged between 1778.9 and 15,680 cm3. One patient with recurrence was subsequently treated with a combination of sclerotherapy and rapamycin, leading to significant mass reduction. CONCLUSIONS: Management of CLOVES syndrome requires a collaborative and multimodal approach. Although surgical debulking is one treatment option, non-invasive medical modalities and sclerotherapy should be considered prior to surgical resection.

BACKGROUND: With the evolving plastic surgery training paradigm, there is an increasing emphasis on aesthetic surgery education during residency. In an effort to improve aesthetic education and to encourage preparation for independent practice, our institution has supported a resident-run aesthetic clinic for over two decades. OBJECTIVES: To provide insight into the educational benefits of a resident-run cosmetic clinic through longitudinal resident follow up and institutional experiential review. METHODS: A retrospective review was conducted to identify all clinic-based aesthetic operations performed between 2009 and 2016. To capture residents' perspectives on the cosmetic resident clinic, questionnaires were distributed to the cohort. Primary outcome measures included: volume and types of cases performed, impact of clinic experience on training, confidence level performing cosmetic procedures, and satisfaction with chief clinic. Unpaired t tests were calculated to compare case volume/type with level of confidence and degree of preparedness to perform cosmetic procedures independently. RESULTS: Overall, 264 operations performed by 18 graduated chief residents were reviewed. Surveys were distributed to 28 chief residents (71.4% completion rate). Performing twenty or more clinic-based procedures was associated with higher levels of preparedness to perform cosmetic procedures independently (P = 0.037). Residents reported the highest confidence when performing cosmetic breast procedures when compared to face/neck (P = 0.005), body/trunk procedures (P = 0.39), and noninvasive facial procedures (P = 0.85). CONCLUSIONS: The continued growth of aesthetic surgery highlights the need for comprehensive training and preparation for the new generation of plastic surgeons. Performing cosmetic procedures in clinic is a valuable adjunct to the traditional educational curriculum and increases preparedness and confidence for independent practice.

Prescription opioid abusers frequently tamper with opioid tablets in order to either accelerate the delivery of the euphoria-inducing agent or to alter the route of delivery, such that it may be delivered intranasally or intravenously. As one strategy to combat the opioid epidemic in the USA, drug manufacturers have begun to explore formulations which resist such tampering by abusers. Techniques to prevent tampering consist of physical barriers to crushing, chewing, and drug extraction, or aversive or antagonistic agents, incorporated within the formulation itself. Recent years have seen the development of numerous extended-release opioid agents, which are described in this review. This article provides a comprehensive summary of the pharmacology, benefits, risks, and processes behind the development of currently available extended-release opioid drugs, as well as a glimpse into promising future formulations.

The relationship of cortical structure and specific neuronal circuitry to global brain function, particularly its perturbations related to the development and progression of neuropathology, is an area of great interest in neurobehavioral science. Disruption of these neural networks can be associated with a wide range of neurological and neuropsychiatric disorders. Herein we review activity of the Default Mode Network (DMN) in neurological and neuropsychiatric disorders, including Alzheimer's disease, Parkinson's disease, Epilepsy (Temporal Lobe Epilepsy - TLE), attention deficit hyperactivity disorder (ADHD), and mood disorders. We discuss the implications of DMN disruptions and their relationship to the neurocognitive model of each disease entity, the utility of DMN assessment in clinical evaluation, and the changes of the DMN following treatment.

BACKGROUND: The tumescent face lift uses the concept of subcutaneous cannula lipodissection of the neck, as opposed to wide skin undermining. Lipodissection mobilizes soft tissue while preserving perforating neurovascular branches. The purpose of this study is two-fold: (1) to compare the skin recruitment with subcutaneous lipodissection of the neck alone versus wide undermining and (2) to examine the effect of superiorly oriented superficial musculoaponeurotic system (SMAS) movement on jowl excursion in the tumescent face lift. METHODS: A cadaveric study was performed on five fresh tissue cadavers. Postauricular skin excursion was measured following subcutaneous lipodissection and then measured again after traditional, wide undermining of the neck skin. Jowl excursion (in reference to the mandibular border) was measured following superiorly oriented SMAS excursion. An electronic force gauge was used to measure force application during measurements. RESULTS: Cannula lipodissection resulted in a mean skin excursion of 41.9 mm. There was no significant difference in skin excursion compared to wide undermining (41.9 mm versus 42.1 mm; p = 0.785). Jowl position, in reference to the mandibular border, moved superiorly by a mean distance of 18.3 mm with vertical SMAS excursion. CONCLUSIONS: Subcutaneous cannula lipodissection results in equivalent skin recruitment in comparison to wide undermining of the neck. A superior vector of pull on the SMAS results in vertical excursion of the jowl in reference to the mandibular border.

Background: Chronic hand ischemia refers to progressive, non-acute ischemic symptoms such as cold intolerance, rest pain, ulceration, tissue necrosis, and digit loss and poses a significant challenge in management. Conservative treatment begins with medical optimization and pharmacologic therapy, but when symptoms persist, surgical intervention may be required. Various operations exist to improve circulation including sympathectomy, arterial bypass, or venous arterialization. The purpose of this study is to systematically review published outcomes and present our experience with each surgical technique. Methods: A systematic review of literature regarding surgical treatment of chronic hand ischemia published between 1990 and 2016 was conducted using PRISMA guidelines. A retrospective-review of surgical interventions for chronic hand ischemia from 2010 to 2016 was then conducted. Primary outcomes included improvement in pain, wound-healing, and development of new ulcerations. Results: The review included 38 eight studies, showing all three techniques were effective in treating chronic hand ischemia. Sympathectomy had the lowest rate of new ulcerations (0.8%); bypass had the highest rate of healing existing ulcerations (89%). Arterialization was associated with consistent pain improvement pain (100%) but more complications (30.8%). Our series included 18 patients with 21 affected hands, 18 sympathectomies, 6 ulnar artery bypasses, and 1 arterialization. Most hands had improvement of wounds (89.5%) and pain (78.9%). No patients developed new ulcerations, but one required secondary amputation. Conclusions: When conservative measures fail to improve chronic hand ischemia, surgical intervention is an effective last line treatment. An algorithmic approach can determine the best operation for patients with chronic hand ischemia.

BACKGROUND: An untoward outcome following breast reconstruction is diminished or complete loss of sensation. As the reconstructive paradigm continues to evolve, sensory restoration following reconstruction remains a research focus. Despite the multitude of published outcomes, there is marked heterogeneity across studies, thus confounding published outcomes. This study critically appraises the literature to summarize outcomes and establish a framework to guide clinical practice and future research. METHODS: A literature review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in an effort to perform a meta-analysis. The Ovid MEDLINE, PubMed, Embase, Scopus, Cochrane, and ClinicalTrials.gov online databases were queried to capture all publications between 1990 and 2017 that investigated postreconstruction breast sensation. The primary outcome of interest was breast sensation following both implant-based and autologous reconstruction with or without neurotization. Secondary outcomes of interest included time to sensory testing and patient-reported outcomes. RESULTS: Overall, 503 titles were screened, from which 37 articles were ultimately included for analysis, accounting for 1299 patients. There was major methodologic variability and inconsistent measurable outcomes across studies. It can be deduced that postoperative sensation returns spontaneously and unpredictably, neurotization enhances the magnitude and rapidity of sensory restoration when compared to nonneurotized reconstruction, and a sensate reconstruction improves patient-reported outcomes. CONCLUSIONS: Significant study design discrepancies exist, making it difficult to combine data and assess results. To effectively study breast sensation and the impact of neurotization, future investigation will depend on standardizing the way in which breast sensation is measured.

The landscape of gender dysphoria has changed dramatically in recent years secondary to increased societal acceptance, legislative changes, and medical providers' increased awareness of the associated psychosocial burden associated with the diagnosis. National and global advocacy efforts, in conjunction with expanded third-party insurance coverage, have resulted in new health care opportunities for patients suffering from gender dysphoria. Delivering quality, streamlined health care to these patients requires a complex multidisciplinary approach, involving multiple medical and mental health disciplines, including plastic surgeons. To accommodate the expanding demand for gender-affirmation surgery, academic medical centers specializing in these procedures are gradually emerging. Advancing surgical techniques in the setting of rising patient demand encourage plastic surgeons to increasingly provide high-quality health care to this diverse patient population in an effort to optimize psychosocial functioning and minimize the burden of gender dysphoria. Although the current literature is replete with the evolving surgical and technical approaches to gender-affirming surgery, there remain critical gaps in the plastic surgery literature describing the delivery of comprehensive care to these patients. To address these gaps, the authors establish a framework that plastic surgeons can use to guide their management of patients with gender dysphoria to optimize surgical and psychosocial outcomes. First, the authors describe a timeline of events that have shaped present-day transgender medicine and characterize the current role of the plastic surgeon in the management of gender dysphoria. Subsequently, the authors discuss psychosocial and ethical considerations surrounding gender dysphoria. Finally, the authors discuss the future scope of transgender medicine.

The purpose of this study was to assess the feasibility of acoustic radiation force impulse shear wave velocity and textural features for characterizing abdominal wall musculature and to identify subject-related and technique-related factors that can potentially affect measurements. Median shear wave velocity measurements for the right external abdominal oblique were the same (1.89 ± 0.16 m/s) for both the active group (healthy volunteers with active lifestyles) and the control group (age and body mass index-matched volunteers from an ongoing hernia study). When corrected for thickness, the ratio of right external abdominal oblique shear wave velocity -to-muscle thickness was significantly higher in the control group than in the active volunteers (4.33 s-1 versus 2.88 s-1; p value 0.006). From the textural features studied for right external abdominal oblique, 8 features were found to be statistically different between the active and control groups. In conclusion, shear wave velocity is a feasible and reliable technique to evaluate the stiffness of the abdominal wall musculature. Sonographic texture features add additional characterization of abdominal wall musculature.

BACKGROUND: Current hernia patient-reported outcome (PRO) measures were developed without patient input, greatly impairing their content validity. OBJECTIVE: The purpose of this study was to develop a conceptual model for PRO measures for ventral hernia (VH) patients. METHODS: Fifteen semi-structured, concept elicitation interviews and two focus groups employing nominal group technique were conducted with VH patients. Patients were recruited between November 2015 and July 2016 over the telephone from a five-surgeon patient cohort at our institution. Iterative thematic analysis identified domains. Reliability and validation were achieved using inter-rater reliability checks and triangulation. RESULTS: Seven framework domains were established: (1) expectations; (2) self and others; (3) surgeon and surgical team; (4) sensation; (5) function; (6) appearance; and (7) overall satisfaction. Overall patient satisfaction was associated with two themes: (1) provider-patient relationship; and (2) patient assessment of post-repair improvement. CONCLUSIONS: VH patients experience a profoundly broad range of reactions to VH repair. A patient-informed PRO instrument that addresses the spectrum of patient-identified outcomes can guide practice, optimizing care targeting VH patients' needs.

BACKGROUND: Clinical indications are expanding for the use of fasciocutaneous free flaps in lower extremity traumatic reconstruction. The authors assessed the impact of muscle versus fasciocutaneous free flap coverage on reconstructive and functional outcomes. METHODS: A multicenter retrospective review was conducted on all lower extremity traumatic free flaps performed at Duke University (1997 to 2013) and the University of Pennsylvania (2002 to 2013). Muscle and fasciocutaneous flaps were compared in two subgroups (acute trauma and chronic traumatic sequelae), according to limb salvage, ambulation time, and flap outcomes. RESULTS: A total of 518 lower extremity free flaps were performed for acute traumatic injuries (n = 238) or chronic traumatic sequelae (n = 280). Muscle (n = 307) and fasciocutaneous (n = 211) flaps achieved similar cumulative limb salvage rates in acute trauma (90 percent versus 94 percent; p = 0.56) and chronic trauma subgroups (90 percent versus 88 percent; p = 0.51). Additionally, flap choice did not impact functional recovery (p = 0.83 for acute trauma; p = 0.49 for chronic trauma). Flap groups did not differ in the rates of flap thrombosis, flap salvage, flap loss, or tibial nonunion requiring bone grafting. Fasciocutaneous flaps were more commonly reelevated for subsequent orthopedic procedures (p < 0.01) and required fewer secondary skin-grafting procedures (p = 0.01). Reconstructive and functional outcomes remained heavily influenced by injury severity. CONCLUSIONS: Muscle and fasciocutaneous free flaps achieved comparable rates of limb salvage and functional recovery. Flap selection should be guided by defect characteristics and reconstructive needs. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
