方法：将40例原发翼状胬肉病例按手术方式分为2组(每组20例)：第一组为小切口组，手术先在翼状胬肉体部切一小口，经其分离结膜与结膜下的变性筋膜组织； 而第二组则先用刀片将翼状胬肉头部从角膜分离，然后再分离结膜与结膜下的变性筋膜组织。第一组分离翼状胬肉头部时采用类似角膜瓣成型的方法，用镊子钝性分离而不是用刀片。分别观察两组的手术时间、疼痛程度和创面愈合，进行比较。

结果：第一组平均手术时间较第二组缩短了7.72min(48.9%，P<0.001)。手术后1，2d第一组的疼痛程度和创面愈合均好于第二组(P<0.001)。另外，第一组的手术可由一名医生完成，而第二组则由两名医生完成。

结论：小切口翼状胬肉手术较传统手术方式更容易操作，效果更好。

METHODS: Totally 40 primary pterygium cases were divided into two groups(n=20 each)according to the protocols: small incision removal versus conventional removal. In our small incision removal, group 1, the pterygium body was cut open with a small incision firstly, through which the conjunctiva was separated from the underlying degenerated Tenon's layer; while in the conventional protocol, group 2, the whole head of pterygium was taken down before the separation. Then the head of pterygium was torn down in our protocol using a forceps instead of cutting it down with a blade, which was facilitated by a special corneal epithelial flap formation method. Surgery time, pain score and corneal wound healing were measured to provide objective comparison of outcome between the two protocols.

RESULTS: In the group using small incision removal, the average surgery time was 7.72min(or 48.9%)shorter than that of the control group using conventional protocol(P<0.001). The pain score was lower and the corneal wound was healed better in day 1 and 2 after the surgery in the small incision group(P<0.001). In addition, the surgery can be done by one surgeon using the small incision protocol, while the surgery using the conventional protocol requires two persons.

CONCLUSION: The small incision pterygium removal protocol was easier to perform and resulted in a better outcome than the conventional protocol.
