1. Location-specific outcomes and complications of endoscopic transorbital approaches: A systematic review with novel anatomical grouping.
This PRISMA-based systematic review of 382 ETOA cases proposes a four-tier anatomical grouping and demonstrates location-dependent outcomes: significant improvements in visual acuity and proptosis, with CSF leak rates varying by site (0% orbital/cavernous; 11.8% extradural; 3.4% intradural). The classification supports anatomy-based risk assessment and counseling while reinforcing the approach’s favorable cosmetic profile.
Impact: Introduces a practical anatomical classification with location-specific outcomes and complications, enabling tailored risk stratification for a cosmetically favorable skull base route.
Clinical Implications: Use the anatomical grouping to select candidates, anticipate risks (e.g., CSF leak patterns), and counsel on functional and cosmetic outcomes when considering ETOA versus transcranial routes.
Key Findings
- Proposed a four-group anatomical classification for ETOA (orbital, cavernous sinus, extradural, intradural).
- Visual acuity improved postoperatively in 70.6% (orbital), 56.3% (cavernous), and 63.3% (intradural) groups.
- Proptosis improvement was high, especially in cavernous (95.7%) and intradural (87.0%) groups.
- CSF leak rates varied by location: 0% (orbital, cavernous), 11.8% (extradural), 3.4% (intradural).
Methodological Strengths
- PRISMA-guided systematic review across 28 studies (n=382).
- Location-specific stratification enabling granular outcome analysis.
Limitations
- Heterogeneity of pathologies and outcome reporting across included studies.
- Limited long-term follow-up data and potential publication bias.
Future Directions: Prospective, multicenter registries with standardized, location-specific outcomes (including cosmetic metrics) and pathology-level stratification.
INTRODUCTION: Endoscopic transorbital approach (ETOA) is gaining recognition due to lower complication rates and better cosmetic outcomes. Nonetheless, there is no clear anatomical grouping system for lesions that ETOA can address, and location-specific complication rates are still lacking. RESEARCH QUESTION: This systematic review provides an anatomical grouping system for ETOA and analyse the location-specific surgical risks and outcomes. MATERIAL AND METHODS: Based on the PRISMA guideline, articles with keywords "Endoscopic" and "Transorbital" were searched and analysed. The cases included are regrouped based on four anatomical locations (I - orbital, II - cavernous sinus, III - extradural, IV - intradural), and outcomes are studied respectively. RESULTS: Data from 28 published articles with 382 patients were identified. There were 113 orbital lesions, 58 cavernous lesions, 18 extradural lesions, and 150 intradural lesions. There was significant post-operative visual acuity improvement in Groups I (70.6 %), II (56.3 %), and IV (63.3 %). Proptosis shows notable improvement rates across all groups, particularly in Groups II (95.7 %) and IV (87.0 %). There was an observed difference in the rate of CSF leak depending on the location of the lesion: 0 % in both Group I and II versus 11.8 % in Group III and 3.4 % in Group IV ( DISCUSSION AND CONCLUSION: This systematic review proposed an anatomical grouping system to analyse location-specific outcomes for ETOA. Our findings highlighted the significance of this new classification for anatomy-based risk assessment. Future, larger-scale, and multicenter research will generate more data, allowing for further stratification of outcomes based on specific pathology subtypes.
2. In Vivo Skin 3-D Surface Reconstruction and Wrinkle Depth Estimation Using Handheld High Resolution Tactile Sensing.
A compact handheld probe using GelSight tactile imaging and a learning-based algorithm reconstructs 3-D skin topography and estimates wrinkle depth with micron-level accuracy. Integrated force sensing standardizes contact, enabling consistent measurements across body locations and reporting a low mean absolute error.
Impact: Provides a portable, quantitative tool for wrinkle assessment, facilitating objective outcome measures in cosmetic dermatology and enabling bedside or field use.
Clinical Implications: Enables standardized, operator-independent wrinkle depth quantification for treatment planning and monitoring (e.g., retinoids, energy devices, injectables), and can serve as an objective endpoint in clinical trials.
Key Findings
- Developed a compact handheld GelSight-based tactile imaging probe with custom elastic gel.
- Learning-based 3-D reconstruction achieved micron-level wrinkle height estimation.
- Integrated load-cell force sensing standardized skin contact, reducing measurement variability.
- Reported a low mean absolute error (12.55) across tested sites.
Methodological Strengths
- Integrated hardware–algorithm design validated with quantitative error metrics.
- Force-controlled acquisition improves reproducibility across operators and sites.
Limitations
- Clinical sample size and participant characteristics are not specified in the abstract.
- Comparisons to gold-standard profilometry/optical systems are not detailed.
- Long-term measurement repeatability and real-world robustness remain to be established.
Future Directions: Head-to-head validation against optical profilometry, larger clinical studies across skin types and ages, and integration into treatment workflows and clinical trial endpoints.
3-D skin surface reconstruction offers promise for objective and quantitative dermatological assessment, but no portable, high-resolution device exists that has been validated and used for depth reconstruction across various body locations. We present a compact 3-D skin reconstruction probe based on GelSight tactile imaging with a custom elastic gel and a learning-based reconstruction algorithm for micron-level wrinkle height estimation. Our probe, integrated with a load cell for force sensing for consistent contact, achieves a mean absolute error of 12.55
3. An Innovative Serum With Retinol, Hydroxypinacolone Retinoate, Peptides, and Silybin Improves Mild Photoaged Facial Skin in Middle-Aged Chinese Women.
A multi-active serum combining retinol, HPR, peptides, and silybin synergistically enhanced TGF-β/Smad and ECM pathways in vitro/ex vivo and improved multiple photoaging endpoints over 8 weeks with excellent tolerability in middle-aged Chinese women.
Impact: Provides integrated mechanistic-to-clinical evidence for a novel retinoid-based combination that may offer potent yet gentler anti-aging benefits, addressing tolerability limits of standard retinoids.
Clinical Implications: Consider retinol+HPR combination with peptide and antioxidant support for patients with mild photoaging and sensitive skin, while advocating for future head-to-head RCTs to guide regimen optimization.
Key Findings
- Retinol plus HPR synergistically activated TGF-β/Smad signaling and ECM gene expression versus retinol alone.
- Silybin further promoted collagen and elastin synthesis in ex vivo models.
- An 8-week clinical study showed significant improvements in wrinkles, elasticity, hydration, barrier function, and pigmentation with excellent tolerability.
Methodological Strengths
- Mechanistic validation via transcriptomics in keratinocyte–fibroblast co-culture and ex vivo UV-exposed skin.
- Clinical translation with multi-domain outcomes over 8 weeks.
Limitations
- Non-randomized, comparator-free clinical design with unspecified sample size.
- Short duration (8 weeks) and single-ethnicity cohort limit generalizability.
Future Directions: Conduct randomized, controlled, head-to-head trials versus retinol or HPR alone, assess long-term safety/tolerability, and validate across diverse skin types.
BACKGROUND: Retinoids are effective anti-aging agents, but their use is often limited by irritation, particularly in Asian skin. Hydroxypinacolone retinoate (HPR), a novel retinoid ester, offers similar benefits with reduced irritation, yet its combined use with retinol remains poorly characterized. Additionally, the integration of peptides and botanical antioxidants like silybin into retinoid-based regimens lacks mechanistic and clinical evidence. AIMS: To investigate the molecular mechanisms and clinical efficacy of a novel serum containing retinol, HPR, peptides, and silybin in improving mild photoaged facial skin in Chinese women. METHODS: Mechanistic effects were investigated using transcriptomic profiling in a keratinocyte-fibroblast co-culture and protein expression analysis in UV-exposed ex vivo skin models. Clinical efficacy was assessed in an 8-week study in middle-aged Chinese women with mild photoaging. RESULTS: Retinol + HPR synergistically activated TGF-β/Smad signaling and enhanced extracellular matrix gene expression compared with retinol alone. The addition of silybin further promoted collagen and elastin synthesis. Clinically, the serum significantly improved wrinkles, elasticity, hydration, barrier function, and pigmentation with excellent tolerability. CONCLUSIONS: This multi-active serum demonstrates a synergistic, well-tolerated anti-aging effect. To our knowledge, this work provides an integrated molecular-to-clinical evaluation of a retinol-HPR-peptide-silybin combination, supporting its potential as a potent yet gentle anti-aging option for sensitive skin.
