Artificial Intelligence Analysis of Periorbital Rejuvenation.

[BACKGROUND] Periorbital rejuvenation surgery aims to restore a youthful appearance to the face. Despite the popularity of these procedures, few objective measurements exist to evaluate their impact on perceived facial aging.

[OBJECTIVES] In this study we aimed to quantify the impact of brow lift and blepharoplasty on age as perceived by convolutional neural network (CNN) algorithms.

[METHODS] A retrospective review was performed on patients who underwent upper blepharoplasty, lower blepharoplasty, and/or brow lift at a single cosmetic practice between 2018 and 2023. Collected data included patient demographics, procedure performed, fat pad resection, and preoperative and postoperative frontal images. Each photograph was analyzed by 4 artificial intelligence (AI) platforms to estimate the change in perceived age following surgery. The estimated age reduction was compared between procedures.

[RESULTS] Of the 153 included patients, 118 underwent blepharoplasty, 12 underwent brow lift, and 23 had both blepharoplasty and brow lift. Across all AI platforms, the mean age estimation percentage error was 10.6%, with a tendency for AI to underestimate true age. Univariate analysis revealed an age reduction following any surgery of 1.03 years (P < .001). When controlling for other variables, brow lift patients saw a mean age reduction of 1.432 years (P = .031). Upper and lower blepharoplasty, patient characteristics, and ancillary procedures were not found to be independently associated with significant age reduction.

[CONCLUSIONS] Brow lifts provide significant reduction in perceived age. When planning for periorbital rejuvenation, a thorough preoperative evaluation should be performed, and additional consideration should be given to brow lifting procedures.
