1. Efficacy and safety of onabotulinumtoxin A in the treatment of platysma prominence: A systematic review and meta-analysis of randomized clinical trials.
Across three randomized controlled trials (n=1003 ITT), onabotulinumtoxinA significantly improved both participant- and clinician-rated platysma prominence at 14, 60, and 120 days versus placebo, with markedly higher patient satisfaction. Safety signals (bruising, hemorrhage, dysphagia/dysphonia) did not differ from placebo.
Impact: This meta-analysis consolidates high-level evidence that neuromodulator treatment yields sustained aesthetic benefits for platysmal bands without added safety risk, informing non-surgical management of neck aging.
Clinical Implications: Clinicians can offer onabotulinumtoxinA for platysmal bands with expectation of meaningful improvement up to 4 months and a safety profile comparable to placebo. Counseling should include the time course of effect and the need for repeat treatments.
Key Findings
- OnabotulinumtoxinA improved participant-rated P-APPS at days 14 (RR 3.64), 60 (RR 3.46), and 120 (RR 2.57), all p<0.01.
- Clinician-rated C-APPS also improved at days 14 (RR 4.03), 60 (RR 3.73), and 120 (RR 2.21), all p<0.01.
- Patient satisfaction was significantly higher at days 14 (RR 5.71), 60 (RR 5.56), and 120 (RR 5.29), all p<0.01.
- No significant differences in safety outcomes (bruising, hemorrhage, swallowing/talking difficulties) versus placebo.
Methodological Strengths
- Systematic review and meta-analysis of randomized controlled trials with large pooled sample (n=1003 ITT).
- Consistent efficacy across multiple timepoints (14, 60, 120 days) and across participant and clinician scales.
Limitations
- Only three RCTs included; potential heterogeneity in injection techniques and dosing not fully explored.
- Follow-up limited to 120 days; long-term durability beyond 4 months remains uncertain.
Future Directions: Head-to-head comparisons across neurotoxins and dosing patterns, standardized outcome reporting, and longer-term follow-up to define durability and retreatment intervals.
2. Ultrasound-Guided Hyaluronidase Injections for the Management of Filler-Induced Arterial Ischemia: A Pictorial Case Series and Systematic Review of Literature.
A pictorial case series plus systematic review (9 studies; 83 total cases) demonstrates that ultrasound-guided intravascular hyaluronidase rapidly resolves arterial ischemia after hyaluronic acid fillers, with delayed treatment linked to slower or incomplete recovery. Early, image-guided intervention is emphasized to optimize outcomes.
Impact: Addresses a vision- and tissue-threatening complication in aesthetic practice with a practical, image-guided rescue that can be rapidly implemented.
Clinical Implications: Clinics performing filler injections should adopt ultrasound capability and protocols for rapid, ultrasound-guided hyaluronidase administration when arterial ischemia is suspected. Training on vascular ultrasound and early recognition workflows can improve salvage rates.
Key Findings
- Across 83 cases, ultrasound-guided hyaluronidase was associated with rapid resolution of ischemic symptoms and ultrasound abnormalities.
- Delayed administration of hyaluronidase correlated with slower or incomplete recovery, underscoring the need for early intervention.
- Ultrasound enabled visualization of intravascular thrombus and precise intravascular enzyme delivery.
- The literature highlights heterogeneity in dosing and technique, indicating a need for standardized protocols.
Methodological Strengths
- Systematic, multi-database search following PRISMA with extraction across 9 studies plus detailed pictorial cases.
- Use of ultrasound both diagnostically and therapeutically increases precision and reduces empiricism.
Limitations
- Evidence base consists of case series and observational reports; no randomized comparisons.
- Heterogeneity in dosing, timing, and ultrasound techniques; potential publication bias.
Future Directions: Develop consensus-driven, ultrasound-guided algorithms with standardized dosing and timing; evaluate outcomes in multicenter prospective registries and pragmatic trials.
3. Weighing the Risk: The Impact of Obesity on 30-Day Complications After Cosmetic Abdominoplasty-An Observational Cohort Study of 1,778 Cases.
Using ACS-NSQIP data from 2008–2022 (n=1,778), obesity (34.8% of patients; mean BMI 35.2±5.0 kg/m² among those with obesity) independently increased the risk of 30-day complications after abdominoplasty. The authors advocate enhanced preoperative screening, consideration of DVT prophylaxis, and tailored perioperative care for obese patients.
Impact: Provides large-scale, contemporary risk estimates for a common cosmetic procedure, enabling evidence-based counseling and perioperative optimization for patients with obesity.
Clinical Implications: Preoperative risk stratification should explicitly factor obesity; consider VTE prophylaxis pathways, optimize comorbidities (e.g., glycemic control), and plan for wound risk mitigation and monitoring.
Key Findings
- Among 1,778 abdominoplasty patients, 34.8% had obesity; obesity independently increased 30-day postoperative complications.
- Findings support consideration of DVT prophylaxis and tailored perioperative care in obese patients.
- Study leverages standardized NSQIP 30-day outcomes for robust benchmarking.
Methodological Strengths
- Large, contemporary, multicenter dataset (ACS-NSQIP) with standardized 30-day outcomes.
- Multivariable modeling supports obesity as an independent risk factor.
Limitations
- Retrospective design with potential residual confounding and database coding limitations.
- Aesthetic-specific variables (e.g., surgical technique nuances, drain use) may be undercaptured.
Future Directions: Prospective registries focused on aesthetic procedures to capture technique-specific variables; randomized thromboprophylaxis strategies in high-risk cohorts.
