目的:观察泪囊鼻腔吻合术中单双黏膜瓣吻合的手术效果。方法:对48例56眼慢性泪囊炎随机分为单瓣组、双瓣组。单瓣组28例31眼,术中切除后瓣仅缝合前瓣;双瓣组20例25眼缝合前后双黏膜瓣,术后观察泪道通畅情况。结果:术后随访6～10mo,单瓣组28眼有效,3眼无效,有效率为90%,双瓣组23眼有效,2眼无效,有效率为92%;两组差异无统计学意义。结论:泪囊鼻腔吻合术中,只吻合前瓣而切除后瓣使操作容易,对手术成功率没有明显影响。

·AIM:To compare the curative effect of the external dacryocystorhinostomy(DCR),using two different patterns of flap anastomosis with suturing of two flaps or anterior flap.·METHODS:Fifty-six eyes 48 patients were randomized and assigned to two groups on the basis of the pattern of flap anastomosis.In double-flap group with 25 eyes 20 patients,posterior and anterior flaps were separately sutured.In single-flap group with 31 eyes 28 patients,only the anterior flaps were sutured after resecting of both posterior flaps.·RESULTS:The time of follow-up was 6-10 months for all patients.The final success rates in double-flap groups were 92% and in single-flap group were 90% respectively.There was no significant statistical difference in success rate between the groups.·CONCLUSION:DCR with double-flap anastomosis has no advantage over only anterior flap.Anastomosis by only anterior flap and resected posterior flap is easier to perform and does not appear adversely to affect the outcome of DCR surgery.·
