Abstract
in English, Chinese

Objective: To evaluate an modified epicanthoplasty which can reduce epicanthic scar in blepharoplasty with mild to moderate epicanthus, by using upper eyelid rotation flap via blepharoplasty incision.

Methods: A clinical data of 34 patients with mild and moderate epicanthus (trial group), who were treated with blepharoplasty and epicanthoplasty by using upper eyelid rotation flap, between July 2016 and October 2017, was retrospectively analyzed. And 38 patients who were treated with blepharoplasty and epicanthoplasty by using traditional "Z" plastic method were recruited as control group. There was no significant difference in age and degree of epicanthus between 2 groups ( P>0.05). The lengths of palpebral fissure were measured at preoperation and at 6 days and 6 months after operation, and the length difference between pre- and post-operation was calculated to evaluate the improvement degree. The effectiveness was evaluated with reference to the scale of epicanthus orthopedics.

Results: All incisions of 2 groups healed by first intention, and all patients were followed up 6 months. The epicanthi of 2 groups were significantly corrected. The inner canthus of trial group had no incision; and there were scars at inner canthus of control group, with obvious hyperplasia in 6 cases. The improvement degree of the length of palpebral fissure in trial group and control group were 3.63%±0.07%, 3.70%±0.05% and 4.64%±0.09%, 4.46%±0.10% at 6 days and 6 months after operation, respectively. There was no significant difference between 2 groups ( t=0.005, P=0.996; t=0.287, P=0.871). The effectiveness was excellent in 20 cases, good in 12 cases, and poor in 2 cases in trial group, with an excellent and good rate of 94.12%; meanwhile, the effectiveness was excellent in 16 cases, good in 16 cases, and poor in 6 cases in control group, with an excellent and good rate of 84.21%. There was no significant difference between 2 groups ( χ2=0.796, P=0.372).

Conclusion: The modified epicanthoplasty by using upper eyelid rotation flap via blepharoplasty incision can significantly reduce epicanthic scar with simple operation and satisfactory effectiveness.

目的: 探讨重睑术中采用经重睑切口的上睑旋转皮瓣矫正轻、中度内眦赘皮的疗效。.

方法: 回顾分析 2016 年 7 月—2017 年 10 月，重睑术中采用经重睑切口的上睑旋转皮瓣矫正轻、中度睑板型内眦赘皮合并单睑的 34 例患者（试验组）临床资料；以同期 38 例接受传统“Z”成形内眦开大术联合重睑术患者为对照（对照组）。两组患者年龄及内侧赘皮分度比较，差异无统计学意义（ P>0.05）。于术前及术后 6 d、6 个月测量眼裂长度，计算眼裂长度改善程度；参照内眦赘皮矫正标准评价手术疗效。.

结果: 两组患者切口均Ⅰ期愈合，并获随访 6 个月。两组内眦赘皮明显矫正。试验组内眦处无切口；对照组遗留瘢痕，其中 6 例增生明显。术后 6 d 试验组及对照组眼裂长度改善程度分别为 3.63%±0.07%、3.70%±0.05%；术后 6 个月分别为 4.64%±0.09%、4.46%±0.10%；两组比较差异均无统计学意义（ t=0.005， P=0.996； t=0.287， P=0.871）。术后 6 个月疗效评价，试验组优 20 例、良 12 例、差 2 例，优良率 94.12%；对照组优 16 例、良 16 例、差 6 例，优良率 84.21%；差异无统计学意义（ χ2=0.796， P=0.372）。.

结论: 经重睑切口的上睑旋转皮瓣矫正轻、中度内眦赘皮手术操作简便、效果满意，内眦处无瘢痕形成。.
