Addressing the Rhino in the Room: ChatGPT Creates "Novel" Patent Ideas for Rhinoplasty.

Background: OpenAI's ChatGPT can generate novel ideas for a number of applications. The aim of this study was to prompt the chatbot to generate possible innovations in aesthetic surgery relating to rhinoplasty. Methods: ChatGPT was prompted to develop rhinoplasty patents. The resulting outputs were tabulated and categorized based on technology domain and anatomic location. A Google Patents search was conducted to find uses of the term "rhinoplasty" between 2021 and 2023. Patents not pertaining to rhinoplasty were excluded. Filed patents were compared with those generated by ChatGPT to determine predictive power. Results: A total of 40 patents resulted from ChatGPT and 42 Google Patents from 2021 to 2023 were included. Patents generated without a detailed description command were related to preoperative planning (35%), intraoperative tools (30%), functional evaluation (15%), and 3D printing and implants (10%). Patents with a detailed description command resulted in the majority being postoperative tools (40%), followed by intraoperative tools (30%), 3D printing and implants (10%), and nonsurgical (10%) categories. The anatomic locations included the airway, dorsum, septum, and nasal tip. ChatGPT's predictive power yielded 45% for the detailed prompting, which was higher than the prompt without the detail command. Conclusions: ChatGPT has reasonable potential to generate ideas for innovations in plastic surgery with the assistance of an experienced surgeon-innovator. With new artificial intelligence generations and updates, chatbots will continue to improve. Determining whether these technologies can assist in the later portions of the patent process beyond idea generation will be crucial.

Bard Versus the 2022 American Society of Plastic Surgeons In-Service Examination: Performance on the Examination in Its Intern Year.

Background: Bard is a conversational generative artificial intelligence (AI) platform released by Google (Mountain View, CA) to the public in May 2023. Objectives: This study investigates the performance of Bard on the American Society of Plastic Surgeons (ASPS) In-Service Examination to compare it to residents' performance nationally. We hypothesized that Bard would perform best on the comprehensive and core surgical principles portions of the examination. Methods: Google's 2023 Bard was used to answer questions from the 2022 ASPS In-Service Examination. Each question was asked as written with the stem and multiple-choice options. The 2022 ASPS Norm Table was utilized to compare Bard's performance to that of subgroups of plastic surgery residents. Results: A total of 231 questions were included. Bard answered 143 questions correctly corresponding to an accuracy of 62%. The highest-performing section was the comprehensive portion (73%). When compared with integrated residents nationally, Bard scored in the 74th percentile for post-graduate year (PGY)-1, 34th percentile for PGY-2, 20th percentile for PGY-3, 8th percentile for PGY-4, 1st percentile for PGY-5, and 2nd percentile for PGY-6. Conclusions: Bard outperformed more than half of the first-year integrated residents (74th percentile). Its best sections were the comprehensive and core surgical principle portions of the examination. Further analysis of the chatbot's incorrect questions might help improve the overall quality of the examination's questions.

Modern Machiavelli? The illusion of ChatGPT-generated patient reviews in plastic and aesthetic surgery based on 9000 review classifications.

BACKGROUND: Online patient reviews are crucial in guiding individuals who seek plastic surgery, but artificial chatbots pose a threat of disseminating fake reviews. This study aimed to compare real patient feedback with ChatGPT-generated reviews for the top five US plastic surgery procedures. METHODS: Thirty real patient reviews on rhinoplasty, blepharoplasty, facelift, liposuction, and breast augmentation were collected from RealSelf and used as templates for ChatGPT to generate matching patient reviews. Prolific users (n = 30) assessed 150 pairs of reviews to identify human-written and artificial intelligence (AI)-generated reviews. Patient reviews were further assessed using AI content detector software (Copyleaks AI). RESULTS: Among the 9000 classification tasks, 64.3% and 35.7% of reviews were classified as authentic and fake, respectively. On an average, the author (human versus machine) was correctly identified in 59.6% of cases, and this poor classification performance was consistent across all procedures. Patients with prior aesthetic treatment showed poorer classification performance than those without (p < 0.05). The mean character count in human-written reviews was significantly higher (p < 0.001) that that in AI-generated reviews, with a significant correlation between character count and participants' accuracy rate (p < 0.001). Emotional timbre of reviews differed significantly with "happiness" being more prevalent in human-written reviews (p < 0.001), and "disappointment" being more prevalent in AI reviews (p = 0.005). Copyleaks AI correctly classified 96.7% and 69.3% of human-written and ChatGPT-generated reviews, respectively. CONCLUSION: ChatGPT convincingly replicates authentic patient reviews, even deceiving commercial AI detection software. Analyzing emotional tone and review length can help differentiate real from fake reviews, underscoring the need to educate both patients and physicians to prevent misinformation and mistrust.

Trends of Medicare Reimbursement Rates for Lower Extremity Procedures.

BACKGROUND: Data collected across many surgical specialties suggest that Medicare reimbursement for physicians consistently lags inflation. Studies are needed that describe reimbursement rates for lower extremity procedures. Our goal is to analyze the trends in Medicare reimbursement rates from 2010 to 2021 for both lower extremity amputation and salvage surgeries. METHODS: The Physician Fee Schedule Look-Up Tool of the Centers for Medicare and Medicaid Services was assessed and Current Procedural Terminology codes for common lower extremity procedures were collected. Average reimbursement rates from 2010 to 2021 were analyzed and adjusted for inflation. The rates of work-, facility-, and malpractice-related relative value units (RVUs) were also collected. RESULTS: We found an overall increase in Medicare reimbursement of 4.73% over the study period for lower extremity surgery. However, after adjusting for inflation, the average reimbursement decreased by 13.19%. The adjusted relative difference was calculated to be (-)18.31 and (-)11.34% for lower extremity amputation and salvage procedures, respectively. We also found that physician work-related RVUs decreased by 0.27%, while facility-related and malpractice-related RVUs increased. CONCLUSION: Reimbursement for lower extremity amputation and salvage procedures has steadily declined from 2010 to 2021 after adjusting for inflation, with amputation procedures being devaluated at a greater rate than lower extremity salvage procedures. With the recent marked inflation, knowledge of these trends is crucial for surgeons, hospitals, and health care policymakers to ensure appropriate physician reimbursement. LEVEL OF EVIDENCE: IV (cross-sectional study).

Trends of Medicare reimbursement rates for gender affirmation procedures.

BACKGROUND: While nearly 1 in 5 Americans receives health insurance coverage through Medicare, literature suggests that Medicare reimbursement is lagging behind inflation for many plastic surgery procedures. AIM: This article evaluates trends in Medicare reimbursement for gender affirmation procedures. METHODS: The most common gender affirmation procedures performed at an urban academic medical center were identified in this cross-sectional study (level 4 evidence). Five nongender surgery codes were evaluated for reference. A standardized formula utilizing relative value units (RVUs) was used to calculate monetary data. Differences in reimbursement between 2014 and 2021 were calculated for each procedure. OUTCOME: The main outcome was inflation-adjusted difference of charges from 2014 to 2021. RESULTS: Between 2014 and 2021, Medicare reimbursement for gender affirmation procedures had an inflation-unadjusted average change of -0.09% (vs +5.63% for the selected nongender codes) and an inflation-adjusted change of -10.03% (vs -5.54% for the selected nongender codes). Trends in reimbursement varied by category of gender-affirming procedure. The overall average compound annual growth rate had a change of -0.99% (vs -0.53% for the selected nongender codes). The average changes in work, facility, and malpractice RVUs were -1.05%, +9.52%, and -0.93%, respectively. CLINICAL IMPLICATIONS: Gender surgeons and patients should be aware that the decrease in reimbursement may affect access to gender-affirming care. STRENGTHS AND LIMITATIONS: Our study is one of the first evaluating the reimbursement rates associated with the full spectrum of gender affirmation surgery. However, our study is limited by its cross-sectional nature. CONCLUSIONS: From 2014 to 2021, Medicare reimbursement for gender affirmation procedures lagged inflation.

Clinical Outcomes Following Resection of Distal Lower Extremity Soft Tissue Sarcomas.

OBJECTIVE: Resection of soft tissue sarcoma (STS) in the distal lower extremity can result in large soft tissue defects that create difficult wounds to manage and significant risks for complications. Often, the anticipated or resultant tissue defect or loss of functional anatomy is an indication for amputation over limb salvage. Soft tissue reconstruction managed by plastic and reconstructive surgery (PRS) may help offer limb salvage as a therapeutic option with acceptable oncologic outcomes and wound complication rates. METHODS: This was a review of 52 patients who underwent resection of STS at the level of the knee or distal between 2010 and 2020. Plastic and reconstructive surgery soft tissue management was utilized in 40.4% (n = 21) of cases, most of whom would have otherwise been considered candidates for amputation. RESULTS: The overall rate of limb salvage was 76.9%. The overall rate of wound complications was 19.2%. The overall rate of negative margins of resection was 92.3%. The 1-, 5-, and 10-year overall survival probabilities were 92%, 85%, and 85%, respectively. Of the 40 limb salvage procedures, two required subsequent amputation, one for multiply recurrent disease and one for necrosis. The wound complication rate was 14.3% in the PRS management group and 22.6% in cases of wound closure managed by the primary surgeon. There were zero instances of total wound or flap loss in PRS- managed closures. When comparing patients with wound complications to those without, there was no difference in age (59.5 ± 21 vs. 51 ± 18 years, p = 0.42), body mass index (31.1 ± 4.8 vs. 26.1 ± 7.1 kg/m2 , p = 0.19), or tumor size (6.8 ± 5.0 vs. 6.4 ± 4.7 cm, p = 0.82). At final follow-up, 67% (n = 35) of patients were alive and disease-free. CONCLUSIONS: Wound complications are not uncommon after resection of distal lower extremity STS. Our experience has been successful in achieving limb salvage in these challenging cases. Without PRS soft tissue management, however, many patients may alternatively be candidates for amputation.

Pressure injuries in COVID-19 patients: A tertiary center experience.

Pressure ulcers continue to severely impact patient outcomes and increase health care costs. We aimed to examine the incidence and risk factors related to pressure ulcers among COVID-19 patients. A retrospective was conducted between March 2020-April 2021. Baseline differences were examined using chi-square and Fischer's exact test. Logistic regression was employed to examine the association of the collected variables to development of new pressure ulcers. 4608 patients were included, of which eighty-three acquired new pressure ulcers. Risk factors were increased age, peripheral artery disease, abnormal albumin levels, but not prone position.

Chondrolaryngoplasty with Endoscopic Direct Visualization of the Vocal Cords: Demonstration of Technique.

SUMMARY: Chondrolaryngoplasty is a surgical procedure that reduces a prominent thyroid cartilage. Demand for chondrolaryngoplasty has significantly increased over recent years in transgender women and nonbinary individuals and has been shown to alleviate gender dysphoria and improve quality of life. When performing chondrolaryngoplasty, surgeons must carefully balance the desire for maximal cartilage reduction with the potential for damage to surrounding structures (ie, the vocal cords) that may result because of overaggressive or imprecise resection. Our institution has adopted the technique of direct vocal cord endoscopic visualization using a flexible laryngoscope for increased safety. Briefly, surgical steps include dissection and preparation for translaryngeal needle placement, endoscopic visualization of the needle placed above the level of the vocal cords, marking of the corresponding level, and resection of the thyroid cartilage. The following article and supplemental video provide further detailed descriptions of these surgical steps as a resource for training and technique refinement.

An Updated Review of Hypertrophic Scarring.

Hypertrophic scarring (HTS) is an aberrant form of wound healing that is associated with excessive deposition of extracellular matrix and connective tissue at the site of injury. In this review article, we provide an overview of normal (acute) wound healing phases (hemostasis, inflammation, proliferation, and remodeling). We next discuss the dysregulated and/or impaired mechanisms in wound healing phases that are associated with HTS development. We next discuss the animal models of HTS and their limitations, and review the current and emerging treatments of HTS.

Comparative Benefits of Open versus Closed Reduction of Condylar Fractures: A Systematic Review and Meta-Analysis.

BACKGROUND: Many fractures of the mandibular condylar neck are amenable to both open reduction and internal fixation (ORIF) and closed treatment. Clinical outcomes following these two modalities remains a topic of debate. This systematic review critically appraises the literature to compare them following these treatment options. METHODS: A systematic review and meta-analysis was performed to test the null hypothesis of no difference in clinical outcomes in ORIF versus closed treatment of mandibular condyle fractures. The PubMed, Embase, Cochrane Library, Elsevier text mining tool database, and clinicaltrials.gov trial registries were queried from 1946 to 2020. The quality of evidence was determined using Grading of Recommendations Assessment, Development, and Evaluation methodology. RESULTS: Of 1507 screened articles, 14 met inclusion criteria. ORIF was favored significantly when evaluating temporomandibular joint pain [relative risk (RR), 0.3; 95% CI, 0.1 to 0.7] (number needed to treat to prevent an outcome in one patient, 3; 95% CI, 2 to 6), laterotrusive movements of the mandible (mean difference, 2.3; 95% CI, 1.7 to 3.0) (standardized mean difference, 0.9; 95% CI, 0.4 to 1.3), and malocclusion (RR, 0.5; 95% CI, 0.4 to 0.7) (number needed to treat to prevent an outcome in one patient, 19; 95% CI, 10 to 200). However, ORIF yielded a higher incidence of postoperative infection (RR, 3.6; 95% CI, 0.9 to 13.8) and must be weighed against the understood risk of facial nerve injury. CONCLUSIONS: Meta-analysis of high-level evidence in randomized controlled trial suggests that ORIF significantly improves functional outcomes, decreases pain, and restores occlusion and jaw symmetry. These long-term benefits must be weighed against the increased risk of postoperative infection and exposure of the facial nerve to potential injury.

Laryngochondroplasty: A Systematic Review of Safety, Satisfaction, and Surgical Techniques.

BACKGROUND: Since first performed in 1975, two main surgical techniques for laryngochondroplasty have evolved: anatomical localization and direct endoscopic visualization. The aim of this study was to evaluate which method is safest and had the highest patient-reported satisfaction rates, and to determine whether these outcomes have changed over time. METHODS: A systematic review and meta-analysis following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed to find and analyze all medical publications related to laryngochondroplasty. Of these studies, patients who underwent laryngochondroplasty for gender-affirmation surgery were evaluated. Surgical and patient-reported outcomes were compared between different surgical techniques and between studies before and after the year 2010. RESULTS: A total of 226 patients have been reported to have undergone laryngochondroplasty for gender-affirmation surgery. Overall transient and long-term complication rates were 14% and 0%, respectively. A 97% satisfaction rate was reported overall. Endoscopic visualization techniques were associated with lower short-term complications (OR, 21.11; 95% CI, 7.56 to 58.93); there was no difference in long-term complications (OR, 7.81; 95% CI, 0.31 to 194.37) or patient satisfaction (OR, 5.73; 95% CI, 0.32 to 101.97). Studies performed before the year 2010 had a significantly greater number of short-term complications compared to studies performed after the year 2010 (OR, 10.16; 95% CI, 3.71 to 27.82), with no difference in long-term complications (OR, 4.56; 95% CI, 0.18 to 113.25) or patient satisfaction (OR, 4.99; 95% CI, 0.59 to 42.20). CONCLUSIONS: All laryngochondroplasty techniques result in high patient satisfaction. Endoscopic visualization may help facilitate safe surgery and should be used in conjunction with anatomical familiarity. Technique choice should be dictated by the surgeon's experience and patient desires.

The Burden of COVID-19 on Surgeons' Financial Relationship with the Industry.

The healthcare system has been greatly affected by the coronavirus disease 2019 (COVID-19) pandemic. The aim of this study was to compare pre-COVID-19 and post-COVID-19 payments between industry and medical providers for all surgeons and subspecialized surgeons. Payment information was obtained from the Open Payments Program database for the 2019 and 2020 reported periods for three physician groups: all physicians, all surgeons, and each surgical subspecialty. Comparison and analysis of payment amount and type between these years was performed for each cohort. Physicians experienced a 36% decrease in industry payments with surgeons experiencing a 30.4% decrease. All surgical subspecialties, including plastic surgery (-30.5%; P < 0.01), experienced a significant decrease in industry payments except for transplant surgery, trauma surgery, and neurological surgery. Charitable contributions and compensation for services other than consulting were the only payment types that increased from 2019 to 2020. The COVID-19 pandemic has significantly impacted industry physician payments across all medical and surgical fields with payment decreases across almost all surgical subspecialties.

Gender-Affirmative Surgery: A Collaborative Approach between the Surgeon and Mental Health Professional.

SUMMARY: Gender incongruence describes a condition in which an individual's gender identity does not align with their sex assigned at birth based on anatomic characteristics. Individuals with gender incongruence may request surgical interventions, and gender-affirmation surgery plays an important role for these individuals. The basis of care derives from principles elucidated in the Standards of Care, international guidelines that help inform clinical decision-making. Historically, mental health care professionals (MHCPs) and surgeons have worked collaboratively to select "appropriate" surgical candidates. However, as understanding of gender identity evolves, so does the relationship between the MHCP and the surgeon. The role of the MHCP has shifted from a requirement to verify an individual's identity to that of supporting and participating in a shared decision-making process between the individual and the health care team. This article discusses the evolution of the relationship between the MHCP and the surgeon and provides insight into the history of this relationship.

Pseudomonas aeruginosa Cytotoxins: Mechanisms of Cytotoxicity and Impact on Inflammatory Responses.

Pseudomonas aeruginosa is one of the most virulent opportunistic Gram-negative bacterial pathogens in humans. It causes many acute and chronic infections with morbidity and mortality rates as high as 40%. P. aeruginosa owes its pathogenic versatility to a large arsenal of cell-associated and secreted virulence factors which enable this pathogen to colonize various niches within hosts and protect it from host innate immune defenses. Induction of cytotoxicity in target host cells is a major virulence strategy for P. aeruginosa during the course of infection. P. aeruginosa has invested heavily in this strategy, as manifested by a plethora of cytotoxins that can induce various forms of cell death in target host cells. In this review, we provide an in-depth review of P. aeruginosa cytotoxins based on their mechanisms of cytotoxicity and the possible consequences of their cytotoxicity on host immune responses.

Nationwide Bibliometric Analysis of Integrated Plastic Surgery Program Directors.

Studies have linked bibliometric indices with the academic level of plastic surgeons, but this relationship has not been explored with residency program directors (PDs). As teachers of the next generation, PDs' academic performance is an important component of residency program success. We sought to identify distinguishing characteristics of integrated plastic surgery programs, focusing on their PD bibliometric indices. Methods: We identified plastic surgery programs based on 2021 Doximity reputation and research output rankings, respectively, and then divided them into four quartiles (Q1-Q4). PD academic history and bibliometric indices (h-index, the number of publications, and citations) were collected through Doximity profiles and program websites: PubMed, Scopus, Google Scholar, American Society of Plastic Surgeons, and Accreditation Council for Graduate Medical Education. Results: Eighty-four programs were identified. There was a significant positive relationship between h-index, the number of publications, and type of research with reputation ranking (P < 0.05). After adjusting for years of experience post-training, h-index (OR = 1.24; P < 0.001) and the number of publications (OR = 1.05, P < 0.001) were significantly associated with reputation ranking. There was a statistically significant relationship between PD research fellowship completion and research output ranking (P < 0.01). After adjusting for years of experience post-training, h-index (OR = 1.05; P = 0.047) and the number of publications (OR = 1.01; P = 0.04) were significantly associated with research output ranking. Conclusion: Higher ranked programs tend to have PDs who have a strong record of scholarly activity, as evidenced by certain bibliometric indices.

Underreporting of Traumatic Brain Injuries in Pediatric Craniomaxillofacial Trauma: A 20-Year Retrospective Cohort Study.

BACKGROUND: Despite clinical concerns associated with pediatric traumatic brain injuries (TBIs), they remain grossly underreported. This is the first retrospective study to characterize concomitant pediatric TBIs and craniomaxillofacial (CMF) trauma patients, including frequency, presentation, documentation, and outcomes. METHODS: An institutional review board-approved retrospective cohort study was performed to identify all pediatric patients presenting with CMF fractures at a high-volume, tertiary trauma center between the years 1990 and 2010. Patient charts were reviewed for demographic information, presentation, operative management, length of stay, mortality at 2 years, dentition, CMF fracture patterns, and concomitant TBIs. Data were analyzed using two-tailed t tests and chi-square analysis. A value of P≤ 0.05 was considered statistically significant. RESULTS: Of the 2966 pediatric CMF trauma patients identified and included for analysis [mean age, 7 ± 4.7 years; predominantly White (59.8%), and predominantly male (64.0%)], 809 had concomitant TBI (frequency, 27.3%). Only 1.6% of the TBI cases were documented in charts. Mortality at 2 years, length of stay in the hospital, and time to follow-up increased significantly from mild to severe TBIs. Concomitant TBIs were more common with skull and upper third fractures than CMF trauma without TBIs (81.8% versus 61.1%; P < 0.05). CONCLUSIONS: Concomitant TBIs were present in a significant number of pediatric CMF trauma cases but were not documented for most cases. CMF surgeons should survey all pediatric CMF trauma patients for TBI and manage with neurology and/or neurosurgery teams. Future prospective studies are necessary to characterize and generate practice-guiding recommendations. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.
