1. A Multicenter, Randomized, Evaluator-Blind, No-Treatment Controlled Study of YVOIRE Y-Solution 720: A Volumizing Hyaluronic Acid Filler for Midface Volume Deficit.
In an evaluator-blind randomized trial in Asian patients, YVOIRE Y-Solution 720 achieved ≥1-grade midface volume improvement in 82% vs 5.1% with no treatment at 26 weeks and maintained 76.2% response at 52 weeks. Adverse reactions were mild and transient, primarily swelling, tenderness, and pain.
Impact: This Level I multicenter RCT provides robust, product-specific evidence of efficacy, durability to 52 weeks, and safety for a volumizing HA filler in midface augmentation, informing clinical decision-making in aesthetic practice.
Clinical Implications: YVOIRE Y-Solution 720 can be offered to suitable patients seeking midface augmentation with expectation of high response rates sustained to 1 year and primarily mild, transient local reactions. Counseling should note evaluator-blind improvements and durability.
Key Findings
- At 26 weeks, ≥1-grade MFVDA-SRS improvement occurred in 82.0% with YYS720 vs 5.1% control (between-group difference 77.0%, 95% CI 66.8–84.0).
- Response durability: 76.2% of YYS720 participants maintained ≥1-grade improvement at 52 weeks.
- Safety profile showed no specific concerns; common local reactions (swelling, tenderness, pain) were mild and transient; GAIS responder rates remained high through 26 weeks.
Methodological Strengths
- Multicenter, randomized, evaluator-blind design with a predefined no-treatment control.
- Longitudinal assessment including durability to 52 weeks and participant-reported GAIS.
Limitations
- No active comparator or participant blinding; control was no-treatment.
- Population limited to Asian participants; generalizability to other populations needs confirmation.
Future Directions: Head-to-head trials versus other volumizing fillers, cost-effectiveness analyses, and studies across diverse populations to confirm generalizability and long-term safety beyond 52 weeks.
2. Botulinum Toxin A for Improving Cosmetic Outcomes in Facial Wound Healing: A Systematic Review, Meta-Analysis, and Dose-Response Evaluation.
Across 15 studies (n=607), BTX-A significantly improved aesthetic outcomes of facial wounds (SMD +0.87 in VAS) and reduced scar width by 0.35 mm. Meta-regression identified a dose-response, with an optimal dosing window of 5–15 U/cm balancing efficacy and safety; adverse event rates were similar to controls and no serious complications occurred.
Impact: By synthesizing efficacy, safety, and dose-response, this meta-analysis delivers practical dosing guidance (5–15 U/cm) for BTX-A to improve scar cosmesis, potentially standardizing perioperative protocols.
Clinical Implications: Clinicians can consider BTX-A at 5–15 U/cm along wound edges to improve aesthetic outcomes while maintaining low adverse event rates; protocols should align dosing to wound length and location, especially in high-visibility facial areas.
Key Findings
- BTX-A improved VAS-based cosmetic scores (SMD 0.87; 95% CI 0.45–1.29; P<0.001).
- Scar width decreased by 0.35 mm (95% CI -0.52 to -0.18; P<0.001) with BTX-A.
- Dose-response: effect size increased by 0.08 SMD per U/cm; 5–15 U/cm optimized efficacy-safety balance; adverse event rates were comparable to control (3.9% vs 3.4%; P=0.75).
Methodological Strengths
- PRISMA 2020-compliant systematic review and meta-analysis including 15 comparative studies.
- Meta-regression quantified dose-response; safety analysis included adverse event comparisons.
Limitations
- Heterogeneity in wound types, dosing protocols, and outcome measures across included studies.
- Potential publication bias and limited long-term (>6–12 months) scar outcome data.
Future Directions: Large, standardized RCTs to confirm optimal dosing by wound type and location, protocolized timing, and long-term aesthetic and functional outcomes; cost-effectiveness analyses in routine practice.
3. Prospective, randomized, controlled clinical study on single-incision laparoscopic cholecystectomy: an analysis of 449 cases from a single center.
In a single-center RCT of 891 patients, SILC matched CLC in operative time and blood loss but produced shorter hospital stays, lower postoperative pain, and better Vancouver scar scores. Complications were marginally higher but not statistically significant, supporting SILC as a cosmetically superior alternative when expertise is available.
Impact: This large randomized comparison provides high-level evidence that a single-incision approach improves cosmetic and recovery outcomes without increasing complications, guiding patient selection and surgical planning in minimally invasive biliary surgery.
Clinical Implications: SILC can be preferentially considered in suitable candidates to enhance cosmetic outcomes and recovery, provided surgeons have adequate experience; counseling should address slightly higher but non-significant trends in certain complications and emphasize scar benefits.
Key Findings
- Operative time and blood loss were similar between SILC and CLC (P=0.907 and P=0.475, respectively).
- SILC reduced hospitalization (1.94 vs 2.25 days; P<0.001), pain scores (2.19 vs 2.80; P=0.016), and improved Vancouver scar scores (2.41 vs 3.54; P=0.020).
- Complication rates (e.g., bile leakage, hernia) were marginally higher in SILC but not statistically significant.
Methodological Strengths
- Large randomized controlled design with head-to-head comparison using conventional instruments.
- Includes patient-reported outcomes and objective scar assessment (Vancouver scar scores).
Limitations
- Single-center study; external validity may be limited.
- Potential learning-curve effects; blinding not feasible for surgeons or patients.
Future Directions: Multicenter RCTs examining long-term hernia and bile leak rates, surgeon learning curves, and cost-effectiveness, as well as patient stratification to optimize selection for SILC.
