Analysis of Influencing Factors of Fold Depth after Double Eyelid Plasty
Objective To investigate the influencing factors of double eyelid depth.Methods From May 2022 to April 2023,the Department of Plastic Surgery of Nantong Bosili Medical Aesthetic Hospital received 102 patients with double eyelid folds(204 lateral eyes),and the cases in which patients and plastic surgeons unanimously evaluated the depth of double eyelid folds were divided into deep group(n=57),normal group(n=80),and shallow group(n=23).The internal measurement of keratomic edge points,pupil midpoint,lateral keratomic heterochromic edge point,refolding distance of the double eyelid fold,pupil midpoint,anatomical double eyelid height,whether there is a depressed scar,and the pixelage width of the double eyelid crease between the perpendicular lines of the internal and external corneal heterochromic edge points were measured.Results There were no significant differences in the reflexural distance of the reflexural fold of the keratoptromatic edge point,the midpoint of the pupil and the lateral corneal heterochromic edge point in the depth group and the normal group(P＞0.05).The retroflexion distance of the interchromatic edge point and the midpoint of the pupil in the shallow group were lower than those in the depth group and the normal group(P＜0.05).The values of anatomical eyelid height and double eyelid creaseline width in the depth group were significantly higher than those in the normal group and shallow group(P＜0.05).The proportion of depressed scars in the deep group was greater than that in the normal group and superficial group,and the difference was statistically significant(P＜0.05).Conclusion Double eyelid depth is divided into anatomical double eyelid depth and expressive double eyelid depth.The depth of the eyelid is related to the anatomical height of the double eyelid,whether there is a depressed scar in the double eyelid line incision,and the surgical method.
