Summary

This summary is machine-generated.

Blepharoplasty significantly rejuvenates appearance, making patients look younger. An artificial intelligence model quantified this effect, showing an average age reduction of approximately two years after the procedure.

Area of Science:

Ophthalmology
Plastic Surgery
Artificial Intelligence

Background:

Blepharoplasty is a common cosmetic procedure to improve eyelid aesthetics.
Quantifying the subjective rejuvenating effect of blepharoplasty objectively is challenging.

Purpose of the Study:

To quantify the rejuvenating effect of blepharoplasty using a deep learning-based artificial intelligence model.
To assess the accuracy of an AI model in predicting apparent age from facial photographs.

Main Methods:

Trained an artificial intelligence model on 47,394 facial images to predict apparent age.
Utilized a retrospective chart review of 103 patients who underwent blepharoplasty.
Analyzed preoperative and postoperative photographs using the AI model to determine age change.

Main Results:

The AI model achieved 75% accuracy with a mean absolute error of 1.38 years on a validation set.
Overall, blepharoplasty patients were predicted to be 0.74 years younger preoperatively and 2.52 years younger postoperatively.
Significant age reduction was observed in specific subgroups, including women undergoing lower blepharoplasty and men undergoing quadrilateral blepharoplasty.

Conclusions:

The developed deep learning algorithm quantifies the rejuvenating effect of blepharoplasty.
On average, blepharoplasty provides an approximate two-year rejuvenating effect.
