The Application of 3-Dimensional Measurement and Grayscale Value Measurement Techniques in Lower Eyelid
Background:
Lower eyelid blepharoplasty addresses under-eye bags and tear troughs, but traditional evaluations lack objectivity. Three-dimensional (3D) imaging and grayscale analysis offer a novel, quantitative approach.
Objectives:
The aim of the authors is 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 (January-June 2023) utilized 3D imaging (EinScan H2) and grayscale analysis to measure preoperative and postoperative changes. Key landmarks and grayscale values were analyzed using SPSS 22.0.
Results:
Postoperative 3D measurements showed reduced sagittal distance (P < .05) and increased grayscale values (P < .05), indicating improved morphology and skin texture. intraclass correlation coefficient values exceeded 0.80, confirming reproducibility.
Conclusions:
The 3D imaging and grayscale analysis provide objective, reliable evaluation of blepharoplasty outcomes, enhancing precision and paving the way for personalized treatment despite technical challenges.
