Conventional thinking when designing biodegradable materials and devices is to tune the intrinsic properties and morphological features of the material to regulate their degradation rate, modulating traditional factors such as molecular weight and crystallinity. Since regenerated silk protein can be directly thermoplastically molded to generate robust dense silk plastic-like materials, this approach afforded a new tool to control silk degradation by enabling the mixing of a silk-degrading protease into bulk silk material prior to thermoplastic processing. Here we demonstrate the preparation of these silk-based devices with embedded silk-degrading protease to modulate the degradation based on the internal presence of the enzyme to support silk degradation, as opposed to the traditional surface degradation for silk materials. The degradability of these silk devices with and without embedded protease XIV was assessed both in vitro and in vivo. Ultimately, this new process approach provides direct control of the degradation lifetime of the devices, empowered through internal digestion via water-activated proteases entrained and stabilized during the thermoplastic process.

Background: Plastic surgery interest groups (PSIGs) provide an invaluable opportunity to enhance medical students' exposure to and knowledge of plastic surgery. Despite this, there have been no studies that provide information on the formation of these groups as well as the aspects that make for a productive PSIG. Methods: An anonymous survey was distributed by email via RedCAP to US medical students who hold leadership positions within their medical school's PSIG. Participants were asked baseline medical school information, the structure of their interest group, and perspectives on the most impactful and challenging components of their interest group. Results: Sixteen members (27.6%) of PSIG leadership completed the survey. Eighty percent reported having a membership of greater than 20 students. Fifty percent of the PSIGs were led by advisors who were medical school or hospital-affiliated faculty. Sixty-nine percent of groups were allocated a predetermined amount of money to fund activities and events throughout the academic year. Based on member feedback, groups reported that interactions with plastic surgery faculty, mentorship opportunities, and research opportunities were the most impactful and beneficial components of their PSIG. Forty-four percent reported that the biggest challenge faced by their PSIG was having a small active member group, followed by a lack of funding. Conclusion: Our study provides an in-depth look at the current structure and impact of PSIGs in the United States. It also provides a framework for medical schools that wish to start a PSIG and suggestions for established groups who wish to revitalize their PSIG structure.

Silk and silk derivatives have emerged as a possible alternative in surgical device development, offering mechanical strength, biocompatibility, and environmental sustainability. Through a systematic review following PRISMA guidelines, this study evaluated silk fibroin's application across pre-clinical and clinical settings, focusing on its role as screws and plates for osteofixation. A comprehensive search yielded 245 studies, with 33 subjected to full-text review and 15 ultimately included for qualitative analysis. The findings underscore silk fibroin's superior properties, including its tunable degradation rates and ability to be functionalized with therapeutic agents. In vivo and in vitro studies demonstrated its efficacy in enhancing bone healing, offering improved outcomes in osteofixation, particularly for craniofacial defects. Silk fibroin's remarkable attributes in biodegradation and drug release capabilities underscore its potential to enhance patient care. Ultimately, silk fibroin's integration into surgical practices promises a revolution in patient outcomes and environmental sustainability. Its versatility, coupled with the continuous progress in fabrication techniques, signals a promising horizon for its widespread acceptance in the medical field, potentially establishing a new benchmark in surgical treatment. Further research is expected to solidify the transition of silk products from basic science to patient care, paving the way for widespread use in various surgical applications.

BACKGROUND: Recent CMS billing changes have raised concerns about insurance coverage for deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study compared the costs and utilization of transverse rectus abdominis myocutaneous (TRAM), DIEP, and latissimus dorsi (LD) flaps in breast reconstruction.

METHOD: The study utilized the National Inpatient Sample database to identify female patients who underwent DIEP, TRAM, and LD flap procedures from 2016 to 2019. Key data such as patient demographics, length of stay, complications, and costs (adjusted to 2021 USD) were analyzed, focusing on differences across the flap types.

RESULTS: A total of 17,770 weighted patient encounters were identified, with the median age being 51. The majority underwent DIEP flaps (73.5%), followed by TRAM (14.2%) and LD (12.1%) flaps. The findings revealed that DIEP and TRAM flaps had a similar length of stay (LOS), while LD flaps typically had a shorter LOS. The total hospital charges to costs using cost-to-charge ratio were also comparable between DIEP and TRAM flaps, whereas LD flaps were significantly less expensive. Factors such as income quartile, primary payer of hospitalization, and geographic region significantly influenced flap choice.

CONCLUSION: The study's results appear to contradict the prevailing notion that TRAM flaps are more cost-effective than DIEP flaps. The total hospital charges to costs using cost-to-charge ratio and hospital stays associated with TRAM and DIEP flaps were found to be similar. These findings suggest that changes in the insurance landscape, which may limit the use of DIEP flaps, could undermine patient autonomy while not necessarily reducing healthcare costs. Such policy shifts could favor less costly options like the LD flap, potentially altering the landscape of microvascular breast reconstruction.

BACKGROUND: In this systematic review, we assessed the therapeutic efficacy and safety of Clostridium histolyticum collagenase (CCH) and tissue subcision (TS) for treating cellulite, which ranges from subtle to pronounced lesions.

METHODS: A systematic review was performed following PRISMA guidelines for CCH and TS treatment to the thigh and gluteal regions. A proportion meta-analysis was then conducted using Stata statistical software.

RESULTS: A total of 14 studies were incorporated into the final analysis. Nine focused on TS and five on CCH injection, collectively reporting outcomes for 1254 patients. Of these, 465 received CCH injection and 789 underwent subcision. For bruising, rates were 89% [95% confidence interval (CI), 71%-96%] with CCH injection and 99% (95% CI, 85%-99%) for subcision; pain requiring analgesic was reported at 74% (95% CI, 55%-87%) for CCH and 60% (95% CI, 43%-76%) for subcision; both showed induration at 7% (95% CI, 5%-11% for CCH, 95% CI, 2%-25% for subcision), whereas skin discoloration was higher post-CCH injection at 16% (95% CI, 10%-26%) compared with 7% (95% CI, 5%-10%) postsubcision.

CONCLUSIONS: Both CCH and TS seem effective treatments for cellulite. However, upon evaluating the adverse outcomes between the two modalities, subcision demonstrated a higher incidence of bruising, albeit similar rates of induration compared with CCH injection. Conversely, the CCH injection group manifested a higher propensity for pain requiring analgesia and notably exhibited increased instances of skin discoloration compared with their subcision patient group. Further standardized research is crucial for more informed cellulite treatment decisions and for comparing efficacy, safety, and cost-effectiveness between TS and CCH.

BACKGROUND: Gluteal augmentation with autologous fat grafting, colloquially referred to as Brazilian butt lift (BBL), is an increasingly common procedure with a highly reported complication profile.

OBJECTIVES: In this study we aimed to analyze the prevalence and characteristics of complications that accompanied these surgeries at ambulatory surgery facilities.

METHODS: Adults patients who experienced fat grafting complications from 2019 to 2021 were identified in QUAD A, formerly known as the American Association for Accreditation of Ambulatory Surgery Facilities (AAAASF, Highland Park, IL, USA), database. Patients and complications were analyzed based on sociodemographic, surgery-, and facility-specific variables with descriptive statistics and logistic regression.

RESULTS: Overall, 436 fat grafting procedures with complications were reported to QUAD A, with an overall complication rate of 0.94%. Of these complications, 164 (37.6%) were confirmed to be from gluteal augmentation procedures. Notably, the number of gluteal augmentation with fat grafting complications decreased from the year 2019 (48) to 2020 (36), then nearly doubled from 2020 to 2021 (69). The majority of patients were female (96.7%), with a mean age of 42.0 years and a mean BMI of 28.3 kg/m2. Wound infection was the most commonly documented complication (22.3%). Of the patients who experienced complications, 35.9% presented to a hospital for their complications and 12.6% required reoperation. Four deaths were described. There was no association between sociodemographic or surgical variables and increased odds of readmission or reoperation (P > .05), except for increasing surgeon number and reoperation (P = .02).

CONCLUSIONS: Gluteal augmentation accounts for a large proportion of complications from fat grafting procedures. Increased reporting requirements may aid in future determination of incidences of complications and improve patient safety.

OBJECTIVE: Three-dimensional printing (3Dp) and modeling have demonstrated increasing utility within plastic and reconstructive surgery (PRS). This study aims to understand the prevalence of how this technology is utilized in craniofacial surgery, as well as identify barriers that may limit its integration into practice.

METHODS: A survey was developed to assess participant demographics, characteristics of 3Dp use, and barriers to utilizing three-dimensional technologies in practice. The survey was distributed to practicing craniofacial surgeons. A secondary literature review was conducted to identify solutions for barriers and potential areas for innovation.

RESULTS: Fifteen complete responses (9.7% response rate) were analyzed. The majority (73%) reported using three-dimensional modeling and printing in their practice, primarily for surgical planning. The majority (64%) relied exclusively on outside facilities to print the models, selecting resources required to train self and staff (55%), followed by the cost of staff to run the printer (36%), as the most common barriers affecting 3Dp use in their practice. Of those that did not use 3Dp, the most common barrier was lack of exposure (75%). The literature review revealed cost-lowering techniques with materials, comparability of desktop commercial printers to industrial printers, and incorporation of open-source software.

CONCLUSIONS: The main barrier to integrating 3Dp in craniofacial plastic and reconstructive surgery practice is the perceived cost associated with utilizing the technology. Ongoing literature highlights the cost-utility of in-house 3Dp technologies and practical cost-saving methods. The authors' results underscore the need for broad exposure for currently practicing attendings and trainees in 3Dp practices and other evolving technologies.

BACKGROUND: Medical students who attend institutions without plastic surgery residency programs are at a disadvantage in the plastic surgery match. We developed an educational program for medical students without home programs called Explore Plastic Surgery to provide an overview of the steps toward a career in plastic surgery. The purpose of this study was to assess the impact, utility, and success of the novel program.

METHODS: Pre- and postevent surveys were distributed to participants. Survey data were analyzed including participant demographics, perceptions of barriers unique to those without home programs, and the overall event utility.

RESULTS: Two hundred seventeen students registered for the program. Ninety-five participants completed the pre-event survey (44%), and of those, 57 participants completed the post-event survey (60%). There was an increase in understanding of the steps toward a career in plastic surgery ( P < 0.001), confidence in overcoming barriers ( P = 0.005), and level of comfort in reaching out to faculty for opportunities ( P = 0.01). There was a decrease in the perceived negative impact that attending medical schools without a home program will have on their abilities to pursue careers in plastic surgery ( P = 0.006).

CONCLUSIONS: After the event, participants demonstrated an increase in their confidence in overcoming barriers and a decrease in their perceptions that attending an institution without a home program would negatively impact their ability to pursue plastic surgery. Initiatives focused on early exposure and recruitment of medical students may be important to promote accessibility and diversity within plastic surgery.
