鼻内镜下钬激光泪囊鼻腔造孔术治疗慢性泪囊炎的疗效随访

目的 观察鼻内镜下钬激光泪囊鼻腔造孔术治疗慢性泪囊炎的疗效，并探讨其影响因素。 方法 应用钬激光于鼻内镜下治疗慢性泪囊炎47例（47只眼），术中造孔后置入扩张的硅胶条，术后随访行泪道冲洗和鼻内镜检查处理。 结果 术后随访3～6个月，治愈率87.2%，好转率6.4%，总有效率（治愈率＋好转率）为93.6%。 结论 鼻内镜下钬激光泪囊鼻腔造孔术后，患者面部无瘢痕，鼻部组织损伤小，手术时间短，出血少，泪液的导流系统不受影响，是传统的泪囊鼻腔吻合手术失败后的良好补救方法。

Outcomes of intranasal endoscopic holmium laser-assisted dacryocystorhinostomy in treatment of chronic dacryocystitis

Objective To observe the outcomes of intranasal endoscopic holmium laser-assisted  dacryocystorhinostomy in the treatment of chronic dacryocystitis. Methods Forty-seven patients (47 eyes) with chronic dacryocystitis underwent intranasal endoscopic holmium laser-assisted dacryocystorhinostomy. The postoperative follow-up included lacrimal irrigation and intranasal endoscopic examination. Results The patients were followed up for 3 to 6 months. The cure rate was 87.2%, the improvement rate was 6.4%, and the total effective rate (cure rate+improvement rate) was 93.6%. Conclusion Intranasal endoscopic holmium laser-assisted dacryocystorhinostomy causes no scar in the face, less nasal tissue damage, shorter operation time and less hemorrhage, and does not affect the lacrimal irrigation system, which allows correction of intranasal causes of failure in traditional dacryocystorhinostomy.
