1. Clinical Observations of the Modified Wedge Resection in Composite Labia Minora and Clitoral Hood Reduction Surgery.
A large single-center series (n=738) found that a modified wedge resection enabling simultaneous labia minora and clitoral hood reduction achieved very high symptom relief and aesthetic satisfaction with low minor complication rates over short-term follow-up. The technique appears straightforward, reproducible, and clinically safe.
Impact: This is one of the largest series reporting combined labia minora and clitoral hood reduction with standardized technique and outcomes, informing practice in a rapidly growing area of female genital cosmetic surgery.
Clinical Implications: Surgeons can consider the modified wedge technique as a first-line option for concurrent labia minora and clitoral hood reduction, counseling patients on high short-term satisfaction and low minor complication risks while emphasizing the need for longer-term follow-up.
Key Findings
- Among 738 patients (mean age 27.6 years), symptom improvement occurred in 99.3% and aesthetic satisfaction in 99.2%.
- Minor complications were infrequent: delayed wound healing 3.3% and perceived asymmetry 1.4%; no major complications reported.
- Overall satisfaction was 96.2% with a mean follow-up of 1.9 months.
Methodological Strengths
- Large sample size with consistent technique and standardized outcomes reporting
- Clear reporting of complications, satisfaction, and symptom relief
Limitations
- Retrospective single-center design with short mean follow-up (1.9 months)
- Lack of control group, limited validated patient-reported outcome measures
Future Directions: Prospective multicenter trials with long-term follow-up should assess durability, sensory/sexual function, and standardized PROMs to benchmark techniques.
BACKGROUND: This study aimed to evaluate the clinical efficacy and safety of a modified wedge resection technique for composite reduction of labia minora hypertrophy and redundant clitoral hood. METHODS: A retrospective analysis was conducted on patients who underwent the modified wedge resection procedure for concurrent labia minora and clitoral hood reduction at the Department of Plastic & Cosmetic Surgery, Women's Hospital of Nanjing Medical University (Nanjing Women and Children's Healthcare Hospital) between July 2019 and December 2024. Descriptive statistics were used to analyze patient demographics, self-reported symptoms, postoperative complications, symptom improvement, aesthetic satisfaction, and overall satisfaction. RESULTS: The study included 738 patients with a mean age of 27.6 ± 6.1 years (range: 18-49). Preoperative motivations and symptoms primarily included vulvar friction discomfort (98.8%), aesthetic concerns (87.1%), dyspareunia (7.9%), and increased residual secretions (7.5%). The mean follow-up duration was 1.9 months (range: 1-6). Postoperative complications consisted of delayed wound healing (24 cases, 3.3%) and perceived asymmetry (10 cases, 1.4%). Preoperative symptoms improved in 99.3% of patients, and 99.2% were satisfied with the aesthetic outcome. Overall, 710 patients (96.2%) reported satisfaction with the surgical results. CONCLUSION: The modified wedge resection technique enables simultaneous correction of labia minora hypertrophy and redundant clitoral hood in a single procedure, yielding consistent and satisfactory aesthetic outcomes. This approach is straightforward, reproducible, and demonstrates favorable clinical safety. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

2. Evaluating Large Language Models as Medical Consultation Tools for Double Eyelid Surgery: A Cross-Language Study in English and Chinese.
Across 16 common consultation questions, top-tier LLMs (e.g., ERNIE-Bot, ChatGPT-4o, Gemini-2.0-Flash in English; DeepSeek-R1 in Chinese) outperformed lower-tier models on professionalism, clarity, and practicality. Findings support LLMs as adjunct tools for double eyelid surgery counseling, while emphasizing the need for medical fine-tuning and surgeon oversight.
Impact: Introduces a bilingual, expert-scored benchmarking of LLMs specifically for a high-volume cosmetic procedure, highlighting which models are currently safest and most informative for patient education.
Clinical Implications: Clinics can triage routine queries using top-performing LLMs to reduce surgeon burden, while implementing guardrails and clinician review for accuracy and individualized recommendations.
Key Findings
- Fifteen LLMs were benchmarked on 16 common questions with English and Chinese inputs, rated by three expert eyelid surgeons across multiple dimensions.
- English: ERNIE-Bot, ChatGPT-4o, and Gemini-2.0-Flash consistently ranked top; Chinese: DeepSeek-R1 led, alongside DeepSeek-V3, Gemini-2.0-Flash, and ERNIE-Bot.
- Lower-tier models (e.g., Claude-3.7-Sonnet/3.5-Haiku, ZoeGPT, CompliantGPT, BastionGPT) lagged significantly across dimensions.
Methodological Strengths
- Bilingual evaluation with expert surgeon ratings and appropriate nonparametric statistical tests
- Comparative benchmarking across a broad set of mainstream LLMs
Limitations
- No assessment of patient-level outcomes or real-world safety; limited to 16 questions
- Dynamic model updates may alter performance; single specialty focus
Future Directions: Fine-tune top models with curated medical corpora; validate in prospective clinical workflows with accuracy auditing, bias checks, and patient-reported outcomes.
BACKGROUND: Double eyelid surgery is a common cosmetic procedure that creates a crease in the upper eyelid. Due to insufficient understanding of the procedure, numerous consultations have emerged, placing a heavy burden on plastic surgeons. The rise of large language models (LLMs) offers a potential solution to this issue. METHODS: This study collected sixteen questions commonly of concern to individuals seeking the surgery via an online questionnaire and assessed the efficacy of fifteen popular LLMs in answering these questions with both English and Chinese inputs. All responses from the LLMs were scored multidimensionally by three expert eyelid plastic surgeons across dimensions including professionalism, patient friendliness, informativeness, practicality, and logical clarity. The scoring results were statistically analyzed using the Friedman test and Nemenyi post-hoc test. RESULTS: With English input, ERNIE-Bot, ChatGPT-4o, and Gemini-2.0-Flash consistently ranked among the top three across most evaluation dimensions. In contrast, Claude-3.7-Sonnet, HuatuoGPT, ZoeGPT, CompliantGPT, and BastionGPT ranked lower across all dimensions, with performance significantly lagging behind the top performers. For Chinese input, DeepSeek-R1 maintained a leading position across all dimensions, forming the first tier alongside DeepSeek-V3, Gemini-2.0-Flash, and ERNIE-Bot. Meanwhile, Claude-3.5-Haiku, ZoeGPT, Llama3.3-70B-Instruct, CompliantGPT, HuatuoGPT, and BastionGPT ranked lower in multiple dimensions, with a significant gap relative to first-tier models. CONCLUSION: This study demonstrated LLMs' potential as medical consultation tools for double eyelid surgery, providing useful guidance for both English and Chinese users. Future research should focus on fine-tuning LLMs with more specialized medical data and exploring workflows for surgeon-LLM collaboration to validate their clinical utility.

3. Costs, Coverage, and Complications: Disparities in Inpatient Alloplastic Facial Implants in the US Healthcare System.
Using national inpatient data (n=68), the study identifies socioeconomic and regional disparities in access to alloplastic facial implants, with low-income and rural patients facing longer stays and underrepresentation in cosmetic and facial feminization procedures. Despite low complication rates, high costs and inconsistent coverage underscore the need for standardized policies and better outpatient data.
Impact: By linking costs, insurance status, and geography to access for both cosmetic and gender-affirming facial implants, the study provides actionable targets for policy and payer reform to improve equity.
Clinical Implications: Clinicians and health systems should advocate for standardized coverage and develop pathways that reduce geographic and financial barriers, particularly for facial feminization surgery, while monitoring outcomes and costs across inpatient and outpatient settings.
Key Findings
- Among inpatient alloplastic facial implants (n=68), lower-income patients were more often publicly insured and had longer hospital stays.
- Cosmetic and gender dysphoria-related procedures were underrepresented in lower-income groups; higher-income, urban patients frequently self-paid in large metropolitan/Pacific regions.
- Overall complication rates were low, yet inpatient admissions incurred high costs, highlighting access and affordability barriers.
Methodological Strengths
- Use of a national inpatient database with standardized coding
- Multifactor analysis linking socioeconomic, insurance, and geographic variables to access and outcomes
Limitations
- Small sample size and restriction to inpatient cases, excluding outpatient procedures
- Potential miscoding and residual confounding inherent to administrative datasets
Future Directions: Integrate outpatient claims and registry data; conduct qualitative studies among marginalized groups; evaluate policy changes on access, costs, and outcomes, particularly for facial feminization surgery.
This study investigates how socioeconomic status, insurance type, and geography shape access to inpatient synthetic facial implant surgery in the United States. Using HCUP-NIS data from 2016 to 2020 (n=68), the authors show that lower-income patients are more likely to be publicly insured, experience significantly longer hospital stays, and are underrepresented in cosmetic and gender dysphoria-related procedures, while higher-income, urban patients more often self-pay for elective implants clustered in large metropolitan and Pacific regions. Despite low overall complication rates, inpatient admissions are associated with high costs, and rural and low-income patients face pronounced barriers to care, particularly for facial feminization surgery. This work highlights the need for broader outpatient data capture, qualitative research among marginalized groups, and standardized insurance coverage policies to promote equitable, cost-effective access to functional and aesthetic facial implant procedures.
