Improving Readability and Automating Content Analysis of Plastic Surgery Webpages With ChatGPT.

INTRODUCTION: The quality and readability of online health information are sometimes suboptimal, reducing their usefulness to patients. Manual evaluation of online medical information is time-consuming and error-prone. This study automates content analysis and readability improvement of private-practice plastic surgery webpages using ChatGPT. METHODS: The first 70 Google search results of "breast implant size factors" and "breast implant size decision" were screened. ChatGPT 3.5 and 4.0 were utilized with two prompts (1: general, 2: specific) to automate content analysis and rewrite webpages with improved readability. ChatGPT content analysis outputs were classified as hallucination (false positive), accurate (true positive or true negative), or omission (false negative) using human-rated scores as a benchmark. Six readability metric scores of original and revised webpage texts were compared. RESULTS: Seventy-five webpages were included. Significant improvements were achieved from baseline in six readability metric scores using a specific-instruction prompt with ChatGPT 3.5 (all P ≤ 0.05). No further improvements in readability scores were achieved with ChatGPT 4.0. Rates of hallucination, accuracy, and omission in ChatGPT content scoring varied widely between decision-making factors. Compared to ChatGPT 3.5, average accuracy rates increased while omission rates decreased with ChatGPT 4.0 content analysis output. CONCLUSIONS: ChatGPT offers an innovative approach to enhancing the quality of online medical information and expanding the capabilities of plastic surgery research and practice. Automation of content analysis is limited by ChatGPT 3.5's high omission rates and ChatGPT 4.0's high hallucination rates. Our results also underscore the importance of iterative prompt design to optimize ChatGPT performance in research tasks.

Assessing the Influence of Intraoperative Core Body Temperature on Postoperative Venous Thromboembolism after Abdominal Wall Reconstruction.

Background: Venous thromboembolism (VTE) is a dangerous postoperative complication after abdominal wall reconstruction (AWR). Intraoperative core body temperature has been associated with thrombotic events in other surgical contexts. This study examines the effects of intraoperative temperature on VTE rate after AWR. Methods: A retrospective study was performed on AWR patients. Cohorts were defined by postoperative 30-day VTE. Intraoperative core body temperature was recorded as the minimum, maximum, and mean intraoperative temperatures. Study variables were analyzed with logistic regression and cutoff analysis to assess for association with VTE. Results: In total, 344 patients met inclusion criteria. Fourteen patients were diagnosed with 30-day VTE for an incidence of 4.1%. The VTE cohort had a longer median inpatient stay (8 days versus 5 days, P < 0.001) and greater intraoperative change in peak inspiratory pressure (3 mm H2O versus 1 mm H2O, P = 0.01) than the non-VTE cohort. Operative duration [odds ratio (OR) = 1.32, P = 0.01], length of stay (OR = 1.07, P = 0.001), and intraoperative PIP difference (OR = 1.18, P = 0.045) were significantly associated with 30-day VTE on univariable regression. Immunocompromised status (OR = 4.1, P = 0.023; OR = 4.0, P = 0.025) and length of stay (OR = 1.1, P < 0.001; OR = 1.1, P < 0.001) were significant predictors of 30-day VTE on two multivariable regression models. No significant associations were found between temperature metrics and 30-day VTE on cutoff point or regression analysis. Conclusions: Intraoperative core body temperature did not associate with 30-day VTE after AWR, though operative duration, length of stay, immunocompromised status, and intraoperative PIP difference did. Surgeons should remain mindful of VTE risk after AWR, and future research is warranted to elucidate all contributing factors.

Neural Interconnections of Extracranial Nerves in Headache Surgery: Anatomical Landmarks and Clinical Implications - A Review of Literature.

Headache disorders (HD) remain a nationwide challenge for the US healthcare system affecting nearly 60% of the US population. Surgical deactivation of the peripheral trigger site, also referred to as headache surgery, represents an effective treatment for patients with refractory HD pain or non-response to pharmacological regimes. Research stemming from other surgical specialties has underlined the clinical relevance of neural interconnections in refining diagnostic algorithms, adapting surgical techniques, and improving overall patient outcomes. While different HD trigger points have been identified, there is a paucity of studies discussing these mostly sensory neural interconnections between these trigger points in a comprehensive fashion. Herein, we aim to provide an overview of the specific nerves involved in HD and synthesize the current literature on HD nerve interconnections to, ultimately, deduce clinical implications. Overall, this line of research may help refine the perioperative workflow and enhance HD patient care.

Diagnosis and Treatment of Perioperative Allergic Complications: A Practical Review.

Background: Reported drug allergies are commonly encountered by surgeons and can lead to uncertainty in selecting an appropriate agent due to concerns of associated risks with related and cross-reactive drugs. This uncertainty can ultimately lead to increased infection rates. Methods: A literature review was conducted in PubMed using a combination of the terms "allergy," "allergic reaction," "anaphylaxis," and "surgery," "surgical," or "operating room" for articles published within the last 10 years. Publications identified with these search terms were then filtered for review articles, sorted by "best match," and a maximum of 100 articles were manually reviewed for each combination of search terms. Results: Search results yielded 46,484 articles, 676 of which were ultimately included for manual review, based on selection criteria. Specifically, articles selected for inclusion focused on surgical allergic reactions that were either related to mechanism of action, causative agent for the allergic reaction, timing of allergic reaction, or recommendations for appropriate management. Conclusions: Allergic reactions can be a common occurrence in the operative room. Knowledge of likely causative agents, timing of a reaction to various agents, and appropriate management in the immediate and delayed setting can improve outcomes and safety for plastic surgery patients.

Practical Review on the Contemporary Diagnosis and Management of Compartment Syndrome.

Acute compartment syndrome (ACS) is a limb-threatening pathology that necessitates early detection and management. The diagnosis of ACS is often made by physical examination alone; however, supplemental methods such as compartment pressure measurement, infrared spectroscopy, and ultrasound can provide additional information that support decision-making. This practical review aims to incorporate and summarize recent studies to provide evidence-based approaches to compartment syndrome for both resource-rich and -poor settings among several patient populations.

The Plastic Surgery Central Application versus ERAS: Which is Preferred?

Background: The Plastic Surgery Central Application (PSCA), designed to provide an equitable and streamlined application for both applicants and programs, was first designed in 2019, piloted in the 2020-21 application cycle, and is now in its fourth cycle in 2023-24. It has included preference signaling since the 2022-23 cycle, a feature in which applicants can send five "signals" to programs to express interest. We surveyed both program directors (PDs) and applicants following the 2023 match on their perceptions of PSCA versus Electronic Residency Application Service (ERAS). Methods: Surveys were deployed to applicants from three integrated plastic surgery programs during the 2022-23 cycle and all PDs. Respondents were asked basic demographic information, which application system they preferred: PSCA or ERAS, how well they were able to highlight/evaluate different areas of the application, and about their experiences specifically with preference signaling. Results: Forty-two (48%) PDs and 93 (29%) applicants responded. Most PDs (72%) and applicants (59%) preferred PSCA, with only 18% and 27% preferring ERAS. The remainder had no preference. Ninety-three percent of applicants reported that the cost savings of the PSCA were important. Most applicants (78%) and PDs (80%) were in favor or strongly in favor of the preference signaling program. Conclusions: Most applicants and PDs prefer PSCA over ERAS. These data, in conjunction with the cost savings, suggest that the PSCA may be a better alternative for the integrated plastic surgery match. Future analyses of these application systems will help provide the best application for prospective residents.

Year-Over-Year Ventral Hernia Recurrence Rates and Risk Factors.

Importance: Recurrence is one of the most challenging adverse events after ventral hernia repair as it impacts quality of life, utilization of resources, and subsequent need for re-repair. Rates of recurrence range from 30% to 80% after ventral hernia repair. Objective: To determine the contemporary ventral hernia recurrence rate over time in patients with previous hernia repair and to determine risk factors associated with recurrence. Design, Setting, and Participants: This retrospective, population-based study used the Abdominal Core Health Quality Collaborative registry to evaluate year-over-year recurrence rates in patients with prior ventral hernia repair between January 2012 and August 2022. Patients who underwent at least 1 prior ventral hernia repair were included and categorized into 2 groups based on mesh or no-mesh use. There were 43 960 eligible patients; after exclusion criteria (patients with concurrent inguinal hernias as the primary diagnosis, nonstandard hernia procedure categories, American Society of Anesthesiologists class unassigned, or no follow-up), 29 834 patients were analyzed in the mesh group and 5599 in the no-mesh group. Main Outcomes and Measures: Ventral hernia recurrence rates. Risk factors analyzed include age, body mass index, sex, race, insurance type, medical comorbidities, American Society of Anesthesiologists class, smoking, indication for surgery, concomitant procedure, hernia procedure type, myofascial release, fascial closure, fixation type, number of prior repairs, hernia width, hernia length, mesh width, mesh length, operative approach, prior mesh placement, prior mesh infection, mesh location, mesh type, postoperative surgical site occurrence, postoperative surgical site infection, postoperative seroma, use of drains, and reoperation. Results: Among 29 834 patients with mesh, the mean (SD) age was 57.17 (13.36) years, and 14 331 participants (48.0%) were female. Among 5599 patients without mesh, the mean (SD) age was 51.9 (15.31) years, and 2458 participants (43.9%) were female. When comparing year-over-year hernia recurrence rates in patients with and without prior mesh repair, respectively, the Kaplan Meier analysis showed a recurrence rate of 201 cumulative events with 13 872 at risk (2.8%) vs 104 cumulative events with 1707 at risk (4.0%) at 6 months; 411 cumulative events with 4732 at risk (8.0%) vs 184 cumulative events with 427 at risk (32.6%) at 1 year; 640 cumulative events with 1518 at risk (19.7%) vs 243 cumulative events with 146 at risk (52.4%) at 2 years; 731 cumulative events with 670 at risk (29.3%) vs 258 cumulative events with 73 at risk (61.4%) at 3 years; 777 cumulative events with 337 at risk (38.5%) vs 267 cumulative events with 29 at risk (71.2%) at 4 years; and 798 cumulative events with 171 at risk (44.9%) vs 269 cumulative events with 19 at risk (73.7%) at 5 years. Higher body mass index; immunosuppressants; incisional and parastomal hernias; a robotic approach; greater hernia width; use of a biologic or resorbable synthetic mesh; and complications, such as surgical site infections and reoperation, were associated with higher odds of hernia recurrence. Conversely, greater mesh width, myofascial release, and fascial closure had lower odds of recurrence. Hernia type was the most important variable associated with recurrence. Conclusions and Relevance: In this study, the 5-year recurrence rate after ventral hernia repair was greater than 40% and 70% in patients with and without mesh, respectively. Rates of ventral hernia recurrence increased over time, underscoring the importance of close, long-term follow up in this population.

Assessing the Relationship between Obesity and Trigger Point-specific Outcomes after Headache Surgery.

Background: Trigger point deactivation surgery is a safe and effective treatment for properly selected patients experiencing migraine, with 68.3%-100% experiencing symptom improvement postoperatively. However, it is still unknown why certain patients do not respond. Obesity has been shown to be associated with worsened migraine symptoms and a decreased response to select pharmacotherapies. This study aimed to determine whether obesity may also be associated with an attenuated response to surgery. Methods: A retrospective chart review was conducted to identify patients who had undergone trigger point deactivation surgery for migraine. Patients were split into obese and nonobese cohorts. Obesity was classified as a body mass index of 30 or higher per Centers for Disease Control and Prevention guidelines. Outcomes and follow-up periods were determined with respect to individual operations. Outcomes included migraine attack frequency, intensity, duration, and the migraine headache index. Differences in demographics, operative characteristics, and operative outcomes were compared. Results: A total of 62 patients were included in the study. The obese cohort comprised 31 patients who underwent 45 total operations, and the nonobese cohort comprised 31 patients who underwent 34 operations. Results from multivariable analysis showed no impact of obesity on the odds of achieving a more than 90% reduction in any individual outcome. The overall rates of improvement (≥50% reduction in any outcome) and elimination (100% reduction in all symptoms) across both cohorts were 89.9% and 65.8%, respectively. Conclusion: Obese patients have outcomes comparable to a nonobese cohort after trigger point deactivation surgery for migraine.

Mesh Strip Repair for Midline Ventral Hernias: A Case Series.

Background: Polypropylene mesh strip repair is a novel method of hernia closure. Currently, there is limited representation in the literature regarding both the reproducibility of this method and its outcomes. The present study sought to analyze a second institution's experience with fascial closure using the mesh strip technique with long-term follow-up. Methods: A retrospective review of all patients undergoing abdominal wall reconstruction by the senior author was performed. Patients undergoing midline ventral hernia repair with mesh strip only fascial closure and greater than 1 year follow-up were including for analysis. Demographic data; operative details; and outcomes, specifically presence and timing of hernia recurrence, were recorded. Results: Eighteen patients met inclusion criteria. Average follow-up was 860 ±â€…307 days. Nine patients (50%) had recurrence of their hernia after repair. Average time to recurrence was 602 ±â€…406 days, with the earliest recurrence occurring at 126 days postoperatively. Seven patients (39%) underwent concurrent anterior component separation (four unilateral, three bilateral), of which there were three recurrences, all occurring in patients with bilateral anterior component separation. Conclusions: The mesh strip repair is a novel technique that shows uncertain reproducibility of outcomes, specifically with concurrent component separation techniques. With the recent Food and Drug Administration approval of a mesh suture, further multi-institutional analysis will allow for better characterization of the outcomes and indications for this technique.

Revisiting Level of Evidence Ratings in Plastic Surgery: A Call to Action.

BACKGROUND: Evidence-based medicine underpins medical and surgical practice, with level of evidence (LOE) being a key aspect that allows clinicians and researchers to better discriminate the methodological context by which studies are conducted and appropriately interpret their conclusions, and more specifically the strength of their recommendations. OBJECTIVES: The aim of this study was to reassess the LOE of articles published in plastic surgery journals. METHODS: To assess the overall LOE of publications from January 1 to December 31, 2021, a review of the following plastic surgery journals was performed: Aesthetic Surgery Journal (ASJ), Annals of Plastic Surgery (Annals), Journal of Plastic Reconstructive and Aesthetic Surgery (JRPAS), Plastic and Reconstructive Surgery (PRS), and Plastic and Reconstructive Surgery Global Open (PRS GO). RESULTS: Of 3698 PUBMED articles, 1649 original articles and systematic reviews were analyzed. The average LOE for each journal was: ASJ 3.02 ± 0.94, Annals 3.49 ± 0.62, JPRAS 3.33 ± 0.77, PRS 2.91 ± 0.77, and PRS GO 3.45 ± 0.70. The collective average LOE was 3.28 ± 0.78. Only 4.4% were LOE 1 and 7.3% were LOE 2. Compared to past studies, PRS showed a significant LOE improvement (P = .0254), while ASJ and JPRAS saw nonsignificant changes; Annals experienced a significant decrease (P = .0092). CONCLUSIONS: ASJ and PRS showed the highest LOE among the journals analyzed. Despite this, low LOE studies remain prevalent in plastic surgery. This paper serves as a call to action for both researchers and academic journals to elevate the standard, offering several strategies to help improve the LOE in plastic surgery.

Socioeconomic Disparities in Research Participation: Bias in Plastic Surgery Residency Match.

Background: Integrated plastic surgery residency applicants have increased at a rate disproportionate to available positions. Research productivity has become a surrogate marker for competitiveness, and many applicants pursue it to distinguish themselves. To date, no study has investigated socioeconomic disparities in extended research experience (ERE) participation. Methods: A 35-question cross-sectional survey was distributed to applicants to United States-based integrated plastic surgery residency programs during the 2019-2022 application cycles. Summary tables, student t test, and chi-square tests were used for statistical analysis. Results: A total of 161 responses (response rate: 20.9%) were recorded. Fifty-nine (40.7%) respondents participated in an ERE. The most common reason for ERE participation was strengthening one's application. The most common reason against participation was avoiding delays in career progression. A greater percentage of respondents from Northeastern medical schools participated in EREs (P = 0.019). There were no significant differences in debt burden between those who did or did not participate in an ERE. A greater percentage of applicants whose parents had advanced degrees participated in EREs (P = 0.053). Conclusions: There may be geographic and socioeconomic biases present in access to ERE for students interested in plastic surgery. The growing popularity of EREs may have unintended consequences for applicant diversity. As most plastic surgeons ultimately practice in nonacademic settings, applicants and plastic surgeons may consider the financial hardships and possible socioeconomic disparities in research opportunities before participating in or recommending them.

Secondary Trigger Point Deactivation Surgery for Nerve Compression Headaches: A Scoping Review.

Background: Primary trigger point deactivation surgery has been successful in reducing or eliminating nerve compression headaches between 79% and 90% of the time. The aim of this review article was to discuss the factors that contribute to index trigger point deactivation surgery failure, the importance of reevaluating trigger points following failure, and the options for secondary surgery. Methods: A literature search was performed using a combination of keywords involving "chronic headache" and "nerve deactivation surgery," in databases until February 2023. Results: Data of 1071 patients were evaluated and included (11 articles). The failure rate after index trigger point deactivation surgery occurs is approximately 12%, primarily due to incomplete primary trigger point deactivation. Secondary trigger points may not appear until the primary trigger is eliminated, which occurs in 17.8% of patients. Reevaluation of previously diagnosed trigger points as well as uncovered trigger points and additional preoperative testing is indicated to help determine candidacy for further surgical deactivation. To address scarring that could contribute to failure, corticosteroid injection, acellular dermal matrix, adipofascial fat, or expanded polytetrafluoroethylene sleeves have been described with beneficial effects. For neuroma management, regenerative peripheral nerve interface, targeted muscle reinnervation, a combination of both, relocation nerve grafting, or nerve capping have also been described. Neurectomy can be performed when patients prefer anesthesia and/or paresthesia over current pain symptoms. Conclusion: Secondary trigger point deactivation surgery is indicated when there is suspicion of incomplete deactivation, internal scarring, neuroma, or newly-diagnosed trigger points.

The Current State of Plastic Surgery Residency Wellness Programs: Benefits and Barriers.

Background: Wellness programs are especially important in residency. However, the resources available to plastic surgery residents through residency wellness programs have not been described. This study reports current plastic surgery residency wellness programs' organization, leadership, and resources. Methods: An anonymous and voluntary e-mail survey was sent to 106 plastic surgery residency program directors through May and June 2022. Features of residency wellness programs were detailed, and program directors' sentiments towards residency wellness programs were evaluated. Results: A 30.2% (32 of 106) complete response rate was achieved. Nearly 90% (87.5%, 28 of 32) of program directors indicated the presence of a wellness program. More than 75% (21 of 28) of programs are supported by the Office of Graduate Medical Education. Wellness events were offered by 92.9% (26 of 28) of programs. More than half of programs offered resources for mental health, physical health, mentorship, and protected time. Several resources were associated with the presence of wellness leadership roles, suggesting residents can positively shape wellness program offerings. Program directors strongly indicated that wellness programs are important, relevant, and effective. Additionally, 75% (24 of 32) report a desire to learn about wellness programs at other plastic surgery residency programs. Conclusions: Resources offered through plastic surgery residency wellness programs are comparable to those in other specialties. However, plastic surgery programs vary in the resources offered to residents and barriers to access exist. Greater involvement of residents in plastic surgery wellness programs may better support physician wellness.

The Fragility of Landmark Randomized Controlled Trials in the Plastic Surgery Literature.

Background: Randomized controlled trials (RCTs) are integral to the progress of evidenced-based medicine and help guide changes in the standards of care. Although results are traditionally evaluated according to their corresponding P value, the universal utility of this statistical metric has been called into question. The fragility index (FI) has been developed as an adjunct method to provide additional statistical perspective. In this study, we aimed to determine the fragility of 25 highly cited RCTs in the plastic surgery literature. Methods: A PubMed search was used to identify the 25 highest cited RCTs with statistically significant dichotomous outcomes across 24 plastic surgery journals. Article characteristics were extracted, and the FI of each article was calculated. Additionally, Altmetric scores were determined for each study to determine article attention across internet platforms. Results: The median FI score across included studies was 4 (2-7.5, interquartile range). The two highest FI scores were 208 and 58, respectively. Four studies (16%) had scores of 0 or 1. Three studies (12%) had scores of 2. All other studies (72%) had FI scores of 3 or higher. The median Altmetric score was 0 (0-3). Conclusion: The FI can provide additional perspective on the robustness of study results, but like the P value, it should be interpreted in the greater context of other study elements.

Prevention and Treatment of Burn Scar Contracture: A Practical Review.

Burn contracture affects close to one-third of all burn patients, leading to significant functional impairment and costs. Effective prevention and treatment strategies are necessary to decrease morbidity and unnecessary costs. This scoping review aimed to summarize prevention and treatment strategies used for management of burn scar contractures published in the literature since 2000. A comprehensive PubMed review was performed in October 2022 to identify methods of burn contracture prevention and treatments. Non-English, duplicate, and unavailable articles were excluded. Data were extracted including publication year, techniques, and outcomes. A total of 327 publications met criteria for inclusion. Most articles were published in 2011 (n = 22). Treatment strategies were discussed in 82.9% of studies, prevention in 16.5%, and both in 0.6%. The most common areas discussed included the upper extremity (n = 127) and neck (n = 102). Flaps were the most frequently used method (n = 208), followed by autografts (n = 89). Most preventative therapies were still in early stages of development. Burn contracture management requires a highly individualized approach with many available reconstructive techniques available. Further research is needed to improve prevention techniques and decrease morbidity and cost to patients.

Postsurgical Pyoderma Gangrenosum Requiring Plastic Surgical Intervention: A Practical Review.

Pyoderma gangrenosum is a neutrophilic dermatosis characterized by immune dysfunction and pathergy. Thus, it is frequently seen in patients with underlying systemic illnesses or postoperatively. For the performance of the debridement or closure of the resultant defect, plastic surgeons are often involved in the care of pyoderma patients. However, both procedures may exacerbate the injury. Therefore, plastic surgeons must be familiar with the presentation of postsurgical pyoderma to avoid further damage and safely repair related soft tissue defects. A systematic search of the PubMed/Medline database was performed using the following keywords: "pyoderma gangrenosum" and "surgery." This online database search has identified 656 studies published between 1958 and 2022. Only reconstructed cases of postsurgical pyoderma gangrenosum were selected. Twenty-eight patients who developed pyoderma after dermatologic, plastic, orthopedic, cardiovascular, general, or obstetric surgery were included in this study. The average time to the PG presentation and diagnosis was 5.5 and 17 days, respectively. Diagnostic scoring tools were not used, and the diagnosis was primarily based on histopathology after repeated treatment failures. The patients received split- or full-thickness skin grafts, local, pedicled, and free flaps. An estimated 82.1% underwent skin grafting, whereas 42.9% underwent flap reconstruction. In addition, 21.4% got both the graft and flap. Accurate diagnosis of PSPG, prevention of further surgical injury, and timely medical management are vital for improving patient outcomes. Reconstruction can be performed, if required. However, despite the availability of different reconstructive techniques, there is no standard approach to the management of the PSPG.

Practical Review of Necrotizing Fasciitis: Principles and Evidence-based Management.

Necrotizing fasciitis is a severe, life-threatening soft tissue infection that presents as a surgical emergency. It is characterized by a rapid progression of inflammation leading to extensive tissue necrosis and destruction. Nonetheless, the diagnosis might be missed or delayed due to variable and nonspecific clinical presentation, contributing to high mortality rates. Therefore, early diagnosis and prompt, aggressive medical and surgical treatment are paramount. In this review, we highlight the defining characteristics, pathophysiology, diagnostic modalities, current principles of treatment, and evolving management strategies of necrotizing fasciitis.

Lower Extremity Reconstruction with Anterolateral Thigh Free-Flap Anastomoses: A Computational Fluid Dynamic Analysis.

BACKGROUND: The anterolateral thigh free flap is an option for repairing soft tissue defects of the distal lower extremity. This flap uses the descending branch of the lateral circumflex femoral (LCF) artery as the flap vessel. The recipient vessel in these flaps is often the anterior tibial (AT), posterior tibial (PT), or peroneal (P) arteries. Computational fluid dynamic (CFD) evaluation of anastomoses between these vessels can optimize outcomes. METHODS: Thirty-eight CFD models were created to model end-to-side (ETS) and end-to-end (ETE) anastomoses for lower extremity reconstruction. Seven out of thirty-eight models represented ETS anastomoses between the LCF and AT arteries with varying anastomotic angles. Nine out of thirty-eight models represented 45-degree ETS anastomoses between varying diameters of the LCF and AT, PT, and P arteries. Nine out of thirty-eight models represented stenosis on the flap vessel and recipient vessel, pre- and post-bifurcation. Nine out of thirty-eight models represented ETE anastomoses, rather than ETS, with varying vessel diameters. Four out of thirty-eight models represented ETE anastomoses with varying regions and levels of stenosis. RESULTS: Stasis of blood flow in ETS models increased as anastomotic angle increased in a logarithmic relationship (R 2 = 0.918). Flow was optimized overall as flap and recipient vessel diameters approached one another. In ETS models, flap vessel and postbifurcation recipient vessel stenosis were found to substantially increase stasis. CONCLUSION: Selection of flap and recipient vessels with similar diameters can optimize outcomes in microvascular anastomoses. In the context of lower extremity reconstruction with the ALT flap, the PT artery can be recommended as a first-line recipient vessel due to its similar vessel caliber to the LCF and relative ease of surgical access compared with the P artery. Avoidance of areas of stenosis is recommended to ensure laminar flow and reduce the operative difficulty associated with performing anastomoses on nonpliable arteries. Striving for increased acuity of anastomotic angles is recommended to optimize the flow in ETS microvascular anastomoses.

Management of Acute Surgical Pain in Plastic and Reconstructive Surgery.

SUMMARY: Fewer than half of all patients undergoing surgery report adequate postoperative pain relief. Poorly managed postoperative pain can lead to complications, increased hospital stays, prolonged rehabilitation, and a decreased quality of life. Pain rating scales are commonly used to identify, manage, and track the perceived intensity of pain. Changes in perceived pain severity and intensity are a key indicator for course of treatment. Postoperative pain is best treated with multimodal management with a variety of analgesic medications and techniques that target different receptors and mechanisms of action in the peripheral and central nervous systems. This includes systemic analgesia, regional analgesia, local analgesia (eg, topical and tumescent analgesia), and nonpharmacologic modalities. It is recommended that this approach is individually tailored and discussed through a shared decision-making approach. This review provides an overview of multimodal management for acute postoperative pain related to plastic surgery procedures. To increase patient satisfaction and provide effective pain control, it is recommended to educate patients on expectations of pain, multimodal options for pain control (including peripheral nerve blocks), complications of unrelieved pain, tracking and monitoring of pain by self-reporting, and how to reduce the use of opioid-based pain medication.
