[摘要] 目的 通过对慢性泪囊炎患者施行泪囊鼻腔吻合术，手术中在制作泪囊鼻黏膜瓣前应用甲基纤维素，评价其在提高泪囊鼻腔吻合术成功率的作用。方法 33例(35眼)慢性泪囊炎患者男6例，女27例，年龄27～56岁。由同一经验丰富的医生施行泪囊鼻腔吻合术，手术中在制作泪囊鼻黏膜瓣前自泪小管向泪囊内注入甲基纤维素，使泪囊膨起，内外侧壁分离，在泪囊、鼻黏膜上做“工”字形黏膜瓣，并对端吻合。结果 在术后5天、10天用无菌生理盐水充分冲洗泪道，泪道通畅，随访6个月～1年，手术均获得成功。无术中、术后并发症发生。结论 甲基纤维素黏度高、弹性好，在泪囊鼻腔吻合术中制作泪囊黏膜瓣前，将甲基纤维素注入泪囊内，泪囊充盈，使泪囊黏膜瓣的制作更准确、完善，提高了手术成功率。

    [Abstract] Objective To operate the dacryocystorhinostomy for the chronic dacryocystitis,during the operation putting methylcellulose into the lacrimal sac that has been cut before.Evalute the function of improving the successful rate on the dacryocystorhinostomy.Methods There are 33 cases(35 eyes)with chronic dacryocystitis,including male six and female 27,age 27～56.The dacryocystorhinostomy was operated by the same experienced doctor.During the operation putting methylcellulose into the lacrimal sac before cut.When the lacrimal sac was swollen to Make valve like“工”type on it.Results Using physiological saline to flush the lacrimal passage fully after the operation for five and ten days to make it smooth.All of the patients were reexamined after six months to one year.All of the operations were successful without any complications.Conclusion The methylcellulose has high sticky and good elasticity.During the operation put methylcellulose into the lacrimal sac before cut.The lacrimal sac was swollen.Making a valve on the lacrimal sac will be more accurate,perfect and raise the successful rate on the dacryocystorhinostomy. ......
