Daily Cosmetic Research Analysis
Three impactful studies in cosmetic and aesthetic surgery stand out today: a multinational registry analysis harmonizing real-world data on breast implant revision incidence; a registry–primary care linkage study showing symptom reductions after cosmetic breast implant explantation but persistent excess vs nonrecipients; and an expert-validated appraisal of large language models for patient information in aesthetic surgery, highlighting transparency gaps.

Three impactful studies in cosmetic and aesthetic surgery stand out today: a multinational registry analysis harmonizing real-world data on breast implant revision incidence; a registry–primary care linkage study showing symptom reductions after cosmetic breast implant explantation but persistent excess vs nonrecipients; and an expert-validated appraisal of large language models for patient information in aesthetic surgery, highlighting transparency gaps.
Research Themes
- Real-world safety and revision outcomes of breast implants
- Breast implant illness symptom trajectories after explantation
- AI-driven patient education quality in aesthetic procedures

1. Comparing International Revision Incidence of Commonly Used Breast Implants.
In a pooled, multicountry registry cohort (Australia and Netherlands) including 150,969 breast implants, overall complication-related revision was 6.3% (reconstructive) and 1.2% (cosmetic). Cosmetic anatomical polyurethane–silicone implants had a lower revision risk vs anatomical textured–silicone (HR 0.38), while no significant 5-year cumulative differences were seen between types.
Impact: Demonstrates feasibility and value of harmonized international registries for real-world device safety, informing implant selection and future regulatory/clinical studies.
Clinical Implications: For cosmetic augmentation, anatomical polyurethane–silicone implants may offer lower revision risk versus anatomical textured–silicone; however, 5-year cumulative differences are minimal across types. Shared decision-making should emphasize comparable medium-term outcomes and the value of continued registry participation.
Key Findings
- Successful harmonization and pooling of Australian and Dutch implant registries enabled multinational time-to-event analysis.
- Overall complication-related revision incidence: 6.3% (reconstructive) vs 1.2% (cosmetic).
- Cosmetic anatomical polyurethane–silicone implants had lower revision risk vs anatomical textured–silicone (HR 0.38; 95% CI 0.22–0.64).
- No significant differences in 5-year cumulative revision incidence across implant types in both reconstructive and cosmetic indications.
Methodological Strengths
- Large, multicenter, population-based registries with harmonized variables across countries.
- Robust time-to-event modeling using frailty Cox regression to account for clustering.
Limitations
- Observational design with potential residual confounding and unmeasured factors (e.g., surgical technique, surgeon experience).
- Five-year horizon may miss longer-term differences; registry capture depends on reporting completeness.
Future Directions: Expand harmonization to additional national registries, include manufacturer-level and surgical technique variables, and extend follow-up to assess long-term outcomes and rare events.
2. The Occurrence of Health Symptoms in General Practice Before and After the Explantation of Cosmetic Breast Implants.
Linking a national implant registry with primary care records, explantation of cosmetic breast implants was associated with significant reductions in multiple symptom burdens within one year, yet symptom likelihood remained higher than in women without implants. Replacement surgery also showed reductions from pre- to postsurgery.
Impact: Provides real-world, clinician-recorded symptom trajectories around explantation, informing the contested discourse on breast implant illness and patient counseling.
Clinical Implications: Patients considering explantation can be counseled that symptom burden often decreases within a year, though not to the level of nonrecipients; expectations should be managed and follow-up planned.
Key Findings
- Retrospective linkage of registry and primary care datasets enabled pre/post comparison around explantation (n=217) with replacement (n=228) and nonrecipient (n=433) comparators.
- Explantation reduced the odds of ≥3 symptoms (OR 0.26), ≥3 consultations (OR 0.56), and substantial symptoms (OR 0.36) within one year.
- Post-explant, symptom likelihood remained higher vs nonrecipients; replacement surgery also showed symptom reductions from pre- to postsurgery.
Methodological Strengths
- Data linkage across a national implant registry and general practice EHRs.
- Multiple comparator groups and pre/post within-subject assessment.
Limitations
- Retrospective design with potential confounding and coding biases.
- One-year window; lack of symptom severity scales and causal inference.
Future Directions: Prospective, longer-term studies incorporating validated symptom scales and biomarkers to elucidate mechanisms and predictors of response to explantation.
3. Assessing the Informational Value of Large Language Models Responses in Aesthetic Surgery: A Comparative Analysis with Expert Opinions.
In a comparative expert evaluation using real patient questions, ChatGPT 3.5 and Google Bard provided moderately accurate and clear answers on dermal fillers, botulinum toxin, and aesthetic blepharoplasty. Lack of source transparency limited credibility assessment, warranting cautious clinical use.
Impact: Addresses a timely and cross-cutting issue by benchmarking AI-generated patient information against expert standards in aesthetic surgery, highlighting current limitations and guiding safe integration.
Clinical Implications: Clinicians should supervise and contextualize AI-derived information, cautioning patients about missing citations and potential omissions. Development and adoption of LLMs with verifiable sources are needed before relying on them as primary educational tools.
Key Findings
- Two LLMs (ChatGPT 3.5 and Google Bard v1.53) answered frequent patient questions across three common aesthetic procedures.
- Thirteen expert aesthetic surgeons rated responses as moderately accurate, clear, and useful overall.
- Source transparency was insufficient, precluding full assessment of credibility and limiting clinical reliance.
Methodological Strengths
- Use of real patient-derived questions spanning multiple procedures.
- Blinded expert panel ratings using standardized Likert scales across key dimensions.
Limitations
- Small sample size and rapidly evolving LLM versions may limit generalizability.
- Lack of quantitative source attribution analysis beyond expert perception.
Future Directions: Conduct larger, multilingual, and longitudinal assessments including versioned LLMs with source citation features; evaluate patient comprehension, safety, and bias correction.
