Effect of Multichannel Convolutional Neural Network-Based Model on the Repair and Aesthetic Effect of Eye Plastic Surgery Patients

Abstract

Objective. This study is aimed at exploring the impact of eye model based on multichannel convolutional neural network (CNN) on eye plastic surgery and aesthetic effect, thus formulating methods to improve the effect of eye plastic surgery. Methods. A total of 64 patients who underwent pouch plastic surgery from January 2020 to March 2021 were selected as the research objects and were divided into observation group and control group by random number table method. The subjects in the observation group were evaluated by multichannel CNN-based eye model and doctors’ experience, while those in the control group were evaluated by doctors’ experience only, with 32 cases in both groups. Blepharoplasty, lower eyelid skin wrinkles, skin luster, and aesthetic scores were compared between the two groups. Results. The similarity between the multichannel CNN model detected shape and the actual eye shape (98.78%) was considerably higher than that of the CNN model detected shape (78.65%) ( P < 0.05 ). After treatment, the indexes of pouch degree, lower eyelid skin wrinkle, eyelid lacrimal sulcus, skin gloss, and aesthetic score in the observation group were better than those in the control group ( P < 0.05 ). The incidence of complications in the observation group (13%) was considerably lower than that in the control group (28%) ( P < 0.05 ). Conclusion. The eye model based on the multichannel CNN model was helpful to improve the surgical repair and aesthetic effect of patients and can improve the occurrence of postoperative complications.

A Narrative Review of Eye-Tracking (ET) Assessment of Esthetic Endpoints in Plastic, Reconstructive, and Craniofacial Surgery

“…Questioning whether beauty attracts the eye, some studies show a “beauty demands longer looks” phenomenon typically explained by biological relevance, personal utility, or other survival factors. This observation is corroborated by a report that observers viewing pre-reconstructive and post-reconstructive surgery images of patients with craniofacial anomaly tend to look less often and for less time at the anomalous side of the face compared with the nonanomalous side 45 . Apparent contradiction between “internal representation of beauty” theory and “beauty demands longer looks” must be viewed in the context that more eye fixation and shorter scanning paths are 2 different attributes of visual processing that are not necessarily mutually exclusive 46 …”

“…Some studies, however, have contradicted this general principle. Observers scan path of some facial rejuvenation studies do not seem to be consistent with the “internal representation of beauty” theory, with conflicting data being reported 45 . Questioning whether beauty attracts the eye, some studies show a “beauty demands longer looks” phenomenon typically explained by biological relevance, personal utility, or other survival factors.…”

Orbital and eyelid diseases: The next breakthrough in artificial intelligence?

“…Yixin et al explored the effect of the eyelid on oculoplastic surgery and aesthetic outcomes by comparing the postoperative metrics of oculoplastic patients assessed by the CNN model with those assessed only artificially. The CNN assessment group had better postoperative extent, lower eyelid skin wrinkles, eyelid tear troughs, skin shine, and aesthetic scores than the control group, suggesting that CNN is a beneficial tool for evaluating oculoplastic surgery (Yixin et al, 2022).…”
