The Application of Three-dimensional Measurement and Grayscale Value Measurement Techniques in Lower Eyelid Blepharoplasty.
Background: Lower eyelid blepharoplasty addresses under-eye bags and tear troughs, but traditional evaluations lack objectivity. 3D imaging and grayscale analysis offer a novel, quantitative approach.
Objectives: To objectively assess blepharoplasty outcomes using 3D imaging and grayscale analysis, validating their effectiveness in capturing morphological and skin texture changes.
Methods: A self-controlled study of 68 patients (Jan-Jun 2023) used 3D imaging (EinScan H2) and grayscale analysis to measure pre- and postoperative changes. Key landmarks and grayscale values were analyzed using SPSS 22.0.
Results: Postoperative 3D measurements showed reduced sagittal distance (P < 0.05) and increased grayscale values (P < 0.05), indicating improved morphology and skin texture. ICC values exceeded 0.80, confirming reproducibility.
Conclusions: 3D imaging and grayscale analysis provide objective, reliable evaluation of blepharoplasty outcomes, enhancing precision and paving the way for personalized treatment despite technical challenges.
