目的 探讨从鼻腔内行鼻腔泪囊造口治疗慢性泪囊炎等所致溢泪。方法 在鼻内窥镜下对 5例因慢性泪囊炎、鼻外伤致泪道阻塞、溢泪 ,行鼻腔泪囊造口 ,并随访 1～ 2年。结果 4例一次性治愈 ,无溢泪 ,冲洗泪道通畅 ;1例术后 2个月因造口瘢痕狭窄、阻塞 ,行造口扩大后治愈。结论 鼻内鼻腔泪囊造口术效果优于眼科鼻外手术方法 ,较好保留泪囊的唧筒功能 ;术中准确定位 ,术后定期冲洗是保证疗效的关键。
Objective To study the nasal lacrimal sac stoma for the treatment of chronic dacryocystitis. Methods Under nasal endoscopy, 5 cases of chronic dacryocystitis, nasal trauma caused by lacrimal duct obstruction, overflow tears, nasal lacrimal sac stoma, and follow-up of 1 to 2 years. Results Four cases were cured at one time without overflow of tears and purging of lacrimal passages. One case had stenosis and occlusion of stoma at 2 months after operation. Conclusions Intranasal nasolacrimal bag ostomy is superior to ophthalmic nasal surgery, and it is better to preserve the function of the pump of the lacrimal sac. Accurate positioning during operation and regular postoperative rinse are the keys to ensure curative effect.
