1. Oncological, surgical, and cosmetic outcomes of endoscopic versus conventional nipple-sparing mastectomy: meta-analysis.
Across 656 patients in comparative analyses and 2612 in proportional analyses, endoscopic nipple-sparing mastectomy achieved higher cosmetic satisfaction with no detriment in short- to mid-term oncologic outcomes relative to conventional techniques. Single-incision approaches reduced postoperative necrosis risk, though operative time and hospital stay were longer.
Impact: This synthesis provides practice-informing evidence that endoscopic approaches can enhance cosmetic satisfaction without compromising oncologic safety, directly addressing patient-centered outcomes in oncoplastic surgery.
Clinical Implications: Endoscopic nipple-sparing mastectomy can be considered for suitable candidates to improve cosmetic satisfaction, especially single-incision techniques, with counseling on longer operative time and hospital stay.
Key Findings
- No significant differences in oncologic outcomes up to a mean of 52 months between endoscopic and conventional nipple-sparing mastectomy.
- Improved cosmetic satisfaction with endoscopic approaches (OR 1.88; P = 0.020).
- Single-incision endoscopic procedures significantly reduced postoperative necrosis (OR 0.19; P = 0.008).
- Endoscopic procedures were associated with longer operative time (+43.08 min) and hospital stay (+0.72 days).
Methodological Strengths
- Systematic review with Newcastle-Ottawa Scale bias assessment and random-effects meta-analyses.
- Both pairwise comparative and proportional meta-analytic approaches increased robustness.
Limitations
- Non-randomized studies dominate; potential residual confounding.
- Follow-up limited to approximately 4 years on average; long-term oncologic equivalence not established.
- Heterogeneity in surgical technique and learning curves may influence outcomes.
Future Directions: Prospective multicenter registries and randomized trials where feasible should assess long-term oncologic and patient-reported outcomes, including standardized cosmetic metrics and cost-effectiveness.
2. AI-assisted mesh generation for subject-specific modeling of facial soft tissues.
An AI-assisted approach using real-time landmark detection generated subject-specific facial soft-tissue meshes with expert-comparable quality (mean Jacobian ratio 0.83) in under a minute, matching simulation performance of an expert-guided workflow. This substantially reduces manual effort and improves scalability for reconstructive and cosmetic surgical planning.
Impact: This methodological innovation delivers order-of-magnitude time savings without compromising mesh quality, enabling broader access to predictive simulations in clinical workflows.
Clinical Implications: Clinics can integrate automated meshing into surgical planning to expedite simulations for orthognathic and cosmetic procedures, facilitating iterative planning and patient counseling.
Key Findings
- AI-assisted mesh generation achieved a mean Jacobian ratio of 0.83, skewness 0.25, and aspect ratio 2.15, comparable to expert-guided meshing.
- Chamfer distance analyses indicated no significant simulation performance differences between AI-assisted and expert-guided methods.
- Processing time decreased from several hours to under one minute without manual landmarking or mesh edits.
Methodological Strengths
- Head-to-head comparison with a clinically validated expert-guided pipeline.
- Objective mesh quality metrics and geometric similarity (Chamfer distance) analyses.
Limitations
- Single dataset with 29 orthognathic surgery subjects; generalizability to diverse anatomies not established.
- Outcome prediction accuracy was inferred from geometric metrics rather than clinical endpoints.
Future Directions: Validate across multimodal imaging, varied facial phenotypes, and prospective clinical trials linking mesh-driven simulations to postoperative outcomes and patient-reported measures.
3. A Retrospective Case Series Study of Illegal Cosmetic Iatrogenic Botulism: Outbreak Analysis and Response Lessons.
Across 161 cases over 10 years, mostly tied to unlicensed providers and counterfeit or unknown botulinum toxin products, severe-to-moderate illness comprised up to 60% with rapid onset after injection. Management included antitoxin and supportive therapies, underscoring urgent needs for surveillance, regulation, and clinician readiness for diagnosis and treatment.
Impact: This is the largest documented series of illicit cosmetic iatrogenic botulism, providing critical epidemiologic and management insights to guide public health surveillance and clinical response.
Clinical Implications: Clinicians should maintain high suspicion for botulism in acute neuromuscular symptoms after cosmetic injections, rapidly initiate antitoxin therapy, and notify public health authorities; regulators should tighten BoNT distribution surveillance and enforce licensing.
Key Findings
- Identified 161 cases of cosmetic iatrogenic botulism over 2014–2024, the largest reported illicit CIB outbreak.
- Majority linked to unknown-origin BoNT administered by unlicensed practitioners in nonmedical settings.
- Severe/moderate disease comprised up to 60%, with peak onset within 3 days post-injection.
- Mean hospital length of stay was 11.64 days; symptoms resolved on average within 24.85 days after treatment.
Methodological Strengths
- Decade-long comprehensive single-center dataset with clinical, laboratory, and therapeutic details.
- Clear description of timelines, severity distribution, and management strategies.
Limitations
- Retrospective single-center design limits generalizability and causal inference.
- Potential under-ascertainment of cases treated elsewhere or not presenting to care.
- Lack of confirmed toxin quantitation/source tracking in all cases.
Future Directions: Establish multicenter surveillance networks and supply-chain tracing for BoNT, standardize clinical pathways for suspected CIB, and evaluate public health interventions to reduce illicit injections.
