To evaluate the recurrence rates and clinical outcome following pterygium surgery using a vertical conjunctival bridge flap technique.
The study included 500 patients operated on for primary or recurrent pterygium during 6 years (between 1994 and 2000). Following receipt of informed consent, the patients were randomly distributed into two treatment groups: 250 patients were operated on using a vertical conjunctival bridge flap technique (Group 1) and the remaining 250 patients were operated on using a bare sclera technique (Group 2). Demographic characteristics of the patients were compared by analysis of variance. The mean follow-up period was 16 months, with a minimum of 6 months. The intraoperative and postoperative complications and recurrence rates were compared for each group.
There was no statistically significant difference in age and gender distribution of the patients between the two groups (P > .05). The most common intraoperative complication was a broken or irregular flap, which was seen in 6 of 250 cases (2%) in the vertical conjunctival bridge flap group. The recurrence rate was 2% in the vertical conjunctival bridge flap group compared with 40% in the bare sclera group (P < .01).
The vertical conjunctival bridge flap technique is a safe and effective method in pterygium surgery and offers low recurrence rates.
评估采用垂直结膜桥瓣技术进行翼状胬肉手术后的复发率及临床疗效。
本研究纳入了6年间（1994年至2000年）因原发性或复发性翼状胬肉接受手术的500例患者。在获得知情同意后，将患者随机分为两个治疗组：250例患者采用垂直结膜桥瓣技术进行手术（第1组），其余250例患者采用单纯巩膜技术进行手术（第2组）。通过方差分析比较患者的人口统计学特征。平均随访期为16个月，最短6个月。比较每组的术中及术后并发症和复发率。
两组患者的年龄和性别分布无统计学显著差异（P >.05）。最常见的术中并发症是瓣破裂或不规则，在垂直结膜桥瓣组的250例中有6例（2%）出现。垂直结膜桥瓣组的复发率为2%，而单纯巩膜组为40%（P <.01）。
垂直结膜桥瓣技术是翼状胬肉手术中一种安全有效的方法，复发率低。
