Abstract:
Objective:To investigate the outcome of epicanthoplasty combined with double eyelidplasty in different aesthetic forms of double eyelids (inner type and outer type) using Z-epicanthoplasty and inverted L method.Methods:The clinical data of patients with single eyelids and epicanthus were retrospectively analyzed from November 2021 to October 2022 in Gaoxin Hospital of the First Affiliated Hospital of Nanchang University. Patients were divided into inner type group and outer type group based on their aesthetic requirements for inner double eyelids. Both groups underwent Z-epicanthoplasty or inverted L method for epicanthus correction. Postoperative follow-up was conducted to observe the incision healing, complications, and postoperative effects of the two groups. The correction effects [ineffective, effective, and markedly effective, with the effective rate calculated as (the number of markedly effective cases + the number of effective cases)/total number of cases × 100%], scar scores, and patient satisfaction scores were collected for more than 12 months after surgery. Independent sample t-test was used for the scar scores and patient satisfaction scores, and chi-square test was used for the epicanthus correction effects. P<0.05 indicated a statistically significant difference. Results:A total of 76 patients were included. Among them, 41 patients in the inner type group (4 males and 37 females, with an average age of 22.3 years, ranging from 18 to 28 years) underwent 19 cases of Z-epicanthoplasty and 22 cases of inverted L method; 35 patients in the outer type group (3 males and 32 females, with an average age of 24.2 years, ranging from 19 to 30 years) underwent 20 cases of Z-epicanthoplasty and 15 cases of inverted L method. After 12 to 16 months of follow-up, with an average of 14 months, all incisions in both groups healed in the first stage, with no significant scar hyperplasia or other complications. Most of the double eyelid shapes are natural after the surgery, and the correction of epicanthus is obvious. Comparison of the treatment efficacy between Z-epicanthoplasty and inverted L method showed no significant difference [94.87% (37/39) vs. 94.59% (35/37), P>0.05]. In the inner type group, the postoperative scar score of the inverted L method was lower than that of the Z-epicanthoplasty [(6.81±0.66) vs. (7.31±0.88)], and the satisfaction score was better than that of the Z-epicanthoplasty [(0.86±0.63) vs. (1.73±0.65)], with statistically significant differences (both P<0.05). In the outer type group, the scar score of the inverted L method was higher than that of the Z-epicanthoplasty [(7.66±0.89) vs. (7.00±0.64)], and the satisfaction score was worse than that of the Z-epicanthoplasty [(1.80±0.86) vs. (1.00±0.56)], with statistically significant differences (both P<0.05). Conclusion:For patients requiring inner type aesthetic form of medial double eyelids, inverted L method can achieve less postoperative scars and higher postoperative satisfaction compared with Z-epicanthoplasty. For patients requiring "outer type" aesthetic form, Z-epicanthoplasty can achieve less postoperative scars and higher postoperative satisfaction compared with inverted L method.
