摘　　要：目的 比较20G自闭式巩膜隧道切口玻璃体切割手术与23G玻璃体切割手术治疗黄斑前膜的临床疗效.方法 随机选取21（21只眼）例黄斑前膜患者,10例（10只眼）行20G自闭式巩膜隧道切口玻璃体切割手术,11（11只眼）例行23G玻璃体切割手术.结果 20G自闭式巩膜隧道切口玻璃体切割手术组切口自行闭合率为93.3%,23G玻璃体切割手术组切口自行闭合率为100%,但两组差异无统计学意义（P〉0.05）.结论 选取合适病例使用20G自闭式巩膜隧道切口玻璃体切割手术,也可以实现切口无需缝合,且操作简捷、术后反应轻、恢复快,无需增加额外操作设备,具备与23G相似的优点,在无条件实施23G玻璃体切割手术时,是理想的替代术式.Objective To compare the efficacy of 20 Gauge three-channel self-sealing sclerotomy pars plana vitrectomy and sutureless 23Gauge pars plana vitrectomy in macula hole surgery. Methods Twenty-one patients were divided into group A and B. Three-channel self-sealing sclerotomy and 23 Gauge pars plana vitrectomy were performed on patients in group A and B respectively. Results The closure rate of sclerotomies was 93.3% in group A; compared to 100% in group B. No significant difference was found between two groups（P 〉0.05）. Conclusions Sutureless surgery can be performed by three-channel self-sealing sclerotomy 20G vitrectomy for appropriate cases with less complication, better recovery and no extra instrument. It might be an alternative substitute for 23Gauge pars plana vitrectomy.
