Summary
Three studies reshape how cosmetic considerations intersect with clinical decision-making. A meta-analysis of randomized trials supports single-incision laparoscopic appendectomy as a viable option for patients prioritizing cosmesis without compromising safety. A systematic review finds thyroidectomy scars have low overall QoL impact, urging added benefits for remote-access approaches. A small analytical case series detects very low BoNT/A levels in breastmilk post-facial injections, informing breastfeeding counseling.
Research Themes
- Cosmetic outcomes integrated into surgical decision-making
- Patient-reported outcomes and scar-related quality of life
- Safety of cosmetic procedures during lactation
Selected Articles
1. Meta-analysis of single-incision versus three-port laparoscopic appendectomy comparing operation time and postoperative pain.
Across 21 RCTs (n=2454), single-incision appendectomy had a nonsignificant 3.8-minute longer operative time versus three-port, a trend toward reduced time differences in recent years, similar pain scores at 12 and 24 hours, and comparable complications and conversion rates. Cosmetic satisfaction was higher with SILA, though 7% required an additional trocar.
Impact: This high-quality meta-analysis of RCTs integrates cosmetic satisfaction with standard surgical outcomes, supporting SILA as a patient-centered option without sacrificing safety.
Clinical Implications: For patients prioritizing cosmetic outcomes, SILA can be offered with counseling about slightly longer operative time and a small chance of needing an extra port, while expecting similar pain and complication profiles to CLA.
Key Findings
- SILA averaged 3.80 minutes longer than CLA (MD 3.80; 95% CI −0.25 to 7.85; p=0.07).
- Meta-regression showed operative time differences decreased in more recent studies (p=0.003).
- CLA required fewer additional analgesics (SMD 0.24; 95% CI 0.10 to 0.38; p<0.01), but pain scores at 12 and 24 hours were not different.
- Postoperative complications and open conversion rates were similar between groups.
- Cosmetic satisfaction favored SILA; 7% of SILA cases required an additional trocar.
Methodological Strengths
- Systematic inclusion of 21 RCTs with exclusion of high risk-of-bias trials
- Meta-regression explored temporal trends, improving interpretability
Limitations
- Heterogeneity in analgesic protocols and outcome definitions across trials
- Limited long-term outcomes; cosmetic satisfaction measures may vary by study
Future Directions: Conduct contemporary RCTs with standardized analgesia and core outcome sets including validated cosmetic and patient-reported outcomes; evaluate hernia and port-site complications over longer follow-up.
2. Impact of Scar on Quality of Life in Well-Differentiated Thyroid Carcinoma: A Systematic Review.
Across 9 studies (14 cohorts; n=3658), scar-related QoL items ranked among the least important concerns in thyroidectomy survivors, often last. Despite biases and heterogeneity, findings were consistent across regions. Remote access thyroidectomy should be justified by benefits beyond cosmetic scar concealment.
Impact: Challenges a prevailing assumption that scar concerns dominate QoL after thyroidectomy, reframing indications for cosmetic-driven remote access approaches.
Clinical Implications: Counsel patients that scar-related QoL burden is generally low; remote access techniques should offer demonstrable functional, oncologic, or recovery advantages to warrant their use.
Key Findings
- In 12/14 cohorts, scar-related QoL items ranked below sixth among domains assessed.
- In 7 cohorts, scar-related items ranked the lowest among all QoL items.
- Thyca-QoL was the most frequently used instrument; common limitations included selection and recall biases.
- Consistency across geographically and culturally diverse populations.
Methodological Strengths
- Comprehensive multi-database search with inclusion of validated QoL instruments
- Large combined sample size (n=3658) and formal study quality assessment (JBI)
Limitations
- Predominantly cross-sectional designs limit causal inference
- Heterogeneity of instruments and timing; potential selection and recall biases
Future Directions: Prospective, longitudinal studies comparing open versus remote access techniques with standardized, validated QoL and cost-effectiveness outcomes.
3. Detection of nontoxic BoNT/A levels in post-facial Botox injection breastmilk.
In a five-participant analytical case series, ELISA detected very low BoNT/A concentrations in breastmilk after facial injections, peaking around day 4 (167 pg/mL) and again near 2 months (133 pg/mL), with detectability up to >1 year. Orthogonal methods (LC-MS, WB, Raman) did not confirm BoNT/A, and levels are likely safe for infants.
Impact: Provides rare human data on BoNT/A in breastmilk after cosmetic use, directly informing risk communication for breastfeeding patients considering Botox.
Clinical Implications: Breastfeeding patients receiving facial Botox may be reassured that detected BoNT/A levels are extremely low; shared decision-making can address timing of injections relative to feeding and individual risk tolerance.
Key Findings
- ELISA detected BoNT/A in breastmilk ranging 34.4–167 pg/mL; peak at 4 days (167 pg/mL) and around 2 months (132.725 pg/mL) post-injection.
- BoNT/A remained detectable in some samples more than a year after injection.
- LC-MS, Western blotting, and confocal micro-Raman spectroscopy did not clearly detect BoNT/A; WB and Raman show promise for future development.
- Authors conclude the measured concentrations are likely safe for infants.
Methodological Strengths
- Multiple orthogonal analytical techniques applied to human breastmilk samples
- Serial sampling across a wide post-injection timeline (hours to >1 year)
Limitations
- Very small sample size (n=5) limits generalizability
- Lack of infant clinical outcomes and inconsistent detection across methods
Future Directions: Larger prospective studies with standardized assays, pharmacokinetic modeling, and linkage to infant outcomes to establish exposure thresholds and clinical guidance.
