Study on the effect of modified Z-correction in double blepharoplasty of bilateral single eyelid with epicanthus
Objective:To analyze the effect of modified Z-correction in patients with single eyelid and epicanthus(bilateral).Methods:Data of 58 patients with single eyelid and epicanthus(bilateral)who underwent double blepharoplasty in our hospital from May 2021 to November 2023 were retrospectively collected.Patients were divided into control group(29 cases received conventional correction of epicanthus)and observation group(29 cases received modified Z-correction)according to different surgical programs.The inner canthus distance(ICD),eyelid cleft length(HLFL),eyelid cleft vertical height,eyelash upturn and exposure length,scar aesthetics[score of Scar Evaluation Scale(OSAS),Vancouver Scar Scale(VSS)and Patient Scar Self-Rating Scale(PSAS)],ocular swelling degree and complication rate of the two groups were analyzed and compared.Results:3 months after operation,ICD and HLFL in observation group were significantly lower than those in control group(P<0.05).Three months after operation,the eyelash upwarping degree,vertical height of eyelid cleft and eyelash exposure length in observation group were significantly increased compared with control group(P<0.05).OSAS,VSS and PSAS scores in the observation group were significantly lower than those in the control group at 1 and 3 months after operation(P<0.05).After 1 month and 3 months,the ocular swelling score of the observation group was significantly lower than that of the control group(P<0.05).The complication rate of the observation group was significantly lower than that of the control group(P<0.05).Conclusion:Modified Z correction for patients with single eyelid and epicanthus(bilateral)can reduce postoperative scar,improve eye appearance,enhance aesthetic effect,reduce swelling degree,and reduce the risk of complications,and the overall effect is better than conventional epicanthus correction.
