目的：探讨显微镜下施行翼状胬肉切除联合下方游离自体球结膜瓣移植术的疗效。 方法：对93例97眼翼状胬肉施行翼状胬肉切除联合下方游离自体球结膜瓣移植术，观察术后恢复情况。 结果：术后随访6~18mo，3眼复发（3％），1眼并发炎性息肉(1％)，无其他并发症。 结论：显微镜下翼状胬肉切除联合下方游离自体球结膜瓣移植术是治疗翼状胬肉的有效方法，具有术后复发率低且不影响白内障、青光眼手术切口选择的优点。

AIM:To study the effect of pterygium excision under microscope combined with free autologous bulbarconjunctiva flap transplantation. METHODS:Totally 93 cases (97 eyes) of pterygium underwent pterygium excision combined with free inferior autologous bulbar conjunctiva graft surgery. The postoperative recovery was observed. RESULTS:Patients were followed up for 6 to 18 months.There were 3 eyes of recurrences (3%), 1 eye of concurrent inflammatory polyp (1%), and no other complications. CONCLUSION:Pterygium excision under microscope combined with autologous free bulbar conjunctiva graft for pterygium surgery is an effective method, with the advantages of lower recurrence rate and without affecting cataract and glaucoma surgical incision.
