目的:寻找用于经内镜鼻腔泪囊造口术时引导泪囊定位的方法。方法:在眼内光导纤维引导下对7例(8眼)慢性泪囊炎患者进行鼻腔泪囊定位。结果:7例患者均顺利完成手术,术中出血10-20ml,术后恢复良好,无感染。5例患者行二次手术,均留置麻醉导管3-6个月后拔管,拔管后每个月行泪囊冲洗1次。随访1年以上无再阻塞,无并发症发生。结论:眼内光导纤维可用于经内镜鼻腔泪囊造口术中进行泪囊定位。
Objective: To find a method for guiding the location of the lacrimal sac during endoscopic nasolacrimal surgery. Methods: Nasal dacryocystorhinostomy was performed in 7 patients (8 eyes) with chronic dacryocystitis under the guidance of intraocular optical fibers. Results: All the 7 patients completed the operation smoothly. The intraoperative blood loss was 10-20ml. The postoperative recovery was good and no infection was found. Five patients underwent second surgery, both indwelling catheter anesthesia 3-6 months after extubation, dredging labrum cleaning once a month after extubation. Follow-up more than 1 year without reocclusion, no complications. CONCLUSIONS: Intraocular optical fibers can be used for lacrimal sac positioning via endoscopic nasolacrimal bag ostomy.
