1. The Impact of Lasers and Energy-Based Devices on Cellular Senescence: A Systematic Review.
This PRISMA-compliant systematic review identified 23 studies showing that lasers and other energy-based devices generally reduce markers of cellular senescence and improve age-related skin changes, suggesting a hormesis-based rejuvenation mechanism. Evidence remains limited but converges on restored cellular signaling and reduced neocarcinogenesis.
Impact: Links clinical rejuvenation outcomes to cellular senescence biology, offering a mechanistic rationale that may unify effects across diverse devices and guide future geroscience-informed protocols.
Clinical Implications: Supports the hypothesis that EBD treatments may modulate senescence pathways; encourages biomarker-informed treatment planning and trials assessing senescence endpoints alongside clinical outcomes.
Key Findings
- PRISMA-based review identified 23 original studies on lasers/EBDs and cellular senescence.
- Across lasers, light-based, and other EBDs, most reports showed reductions in senescence markers with clinical improvement of age-related changes.
- Authors propose hormesis as a convergent mechanism restoring signaling and reducing neocarcinogenesis, while highlighting the scarcity of rigorous data.
Methodological Strengths
- PRISMA-guided systematic search across multiple databases (PubMed, EBSCO, Web of Science).
- Cross-modality synthesis spanning lasers, radiofrequency, ultrasound, photobiomodulation, PDT, and IPL.
Limitations
- Limited number of mechanistic human studies and heterogeneity in senescence endpoints.
- No quantitative meta-analysis due to variability in devices, protocols, and biomarkers.
Future Directions: Prospective trials incorporating standardized senescence biomarkers, dose–response mapping for hormesis, and head-to-head device comparisons to define mechanistic and clinical correlates.
2. Comparing ChatGPT Informed Consent Documentations for Energy-Based Devices.
Using standardized prompts, ChatGPT-4 generated consent forms for 8 energy-based devices that experts rated variably: radiofrequency microneedling scored highest, while monopolar RF scored lowest. Documentation of expected pain and post-procedure restrictions was stronger than general descriptions, and inaccuracies occurred, underscoring the need for dermatologist oversight.
Impact: Timely evaluation at the intersection of AI and cosmetic dermatology provides actionable guidance on when and how to safely deploy language models in consent workflows.
Clinical Implications: Clinics can leverage AI to draft readable consent forms but must implement expert review, device-specific revisions, and quality control to prevent omissions and inaccuracies.
Key Findings
- ChatGPT-4 consent forms showed variable quality across 8 devices; radiofrequency microneedling scored highest (2.75/3), monopolar RF lowest (1.85).
- Expected pain (2.68) and restrictions (2.5) were consistently well-documented; general descriptions (2.16) and overall impression (2.05) were least complete.
- Some content was incomplete or inaccurate, indicating that AI outputs require dermatologist oversight before clinical use.
Methodological Strengths
- Standardized prompts across devices with blinded, independent ratings by five board-certified dermatologists.
- Multi-domain rubric assessing accuracy and completeness (procedures, benefits, risks, alternatives, overall).
Limitations
- Small expert panel and limited to eight device categories; no patient comprehension outcomes.
- Single AI model/version and prompt set; generalizability to other models or clinical contexts is uncertain.
Future Directions: Prospective, randomized studies comparing AI-assisted vs. standard consents on patient comprehension, decisional conflict, and safety; development of validated, specialty-curated prompt libraries.
3. L-Shaped Zygotomy: A Safe and Versatile Modification of the Zygomatic Approach with Quantitative and Cosmetic Advantages in Skull Base Surgery.
In 35 patients, L-shaped zygotomy achieved 71% gross total resection with no new permanent facial palsy or wound complications and excellent long-term cosmetic scores. Cadaveric and 3D model analyses confirmed reduced flap retraction (−11 mm) and expanded anterior corridor (+3.9–4.2 mm) compared with conventional zygotomy.
Impact: Demonstrates a technique that quantitatively improves exposure while safeguarding function and cosmesis, addressing key barriers to broader adoption of zygomatic approaches.
Clinical Implications: Offers a reproducible approach for skull-base access that minimizes flap retraction and preserves facial contour, with validated long-term cosmetic outcomes and the option to escalate to OZ when needed.
Key Findings
- Retrospective series of 35 patients achieved 71% gross total resection with no new permanent facial palsy or wound complications.
- Mean follow-up 46 ± 14 months showed excellent cosmetic outcomes (surgeons 4.4/5, patients 4.7/5).
- Cadaveric and 3D model validation demonstrated 11 mm less skin flap retraction and 3.9–4.2 mm anterior corridor expansion versus conventional zygotomy.
Methodological Strengths
- Combines clinical outcomes with cadaveric and 3D-printed model quantitative validation.
- Independent surgeon and patient-reported cosmetic assessments with long-term follow-up.
Limitations
- Single-center retrospective design with no randomized comparison to conventional techniques.
- Limited sample size and potential selection bias; external validity requires multicenter validation.
Future Directions: Prospective multicenter comparisons with standardized cosmetic and functional endpoints; biomechanical studies optimizing osteotomy parameters and fixation for stability and cosmesis.
