[Clinical analysis of epicanthus correction with two methods: Z-plasty and Y-V plasty].

Objective To compare the clinical effects of different surgical methods for the epicanthus corrective surgery. Methods Canthoplasty with asymmetric Z-flap is applied in 46 cases, Y-V advancement procedure for epicanthoplasty is applied in 42 cases. The epicanthus aesthetic measurement were measured and calculated by software before and after surgery, the diameter of the iris was measured as a reference value, and the postoperative scar was assessed by VSS scale.At the same time, by measuring the lateral canthal distance, the accuracy of the measurement method can be verified. Results All patients were satisfied with the long-term results and there were no recurrences of the epicanthal fold. The shortening ratio of the ICD is 8.36% in the group with the Z-plasty, and 5.88% in Y-V plasty. the lateral canthal distance have no diffrence before and after surgery. Conclusions Two surgical methods can get good results.The magnitude of correction in Z-plasty may larger than Y-V plasty.but postoperative retraction may existed in Z plasty. Key words: Epicanthoplasty; Z-plasty; Y-V plasty
