方法：慢性泪囊炎合并上泪道阻塞患者68例68眼，采用随机数字表法分为A组和B组，每组34例。A组采用鼻内镜下泪囊鼻腔吻合联合硅胶管置入术。B组采用传统泪囊鼻腔吻合联合硅胶管置入术，所有患者均随访1a。

结果：A组患者治疗总有效率为82%，B组为79%，两组比较差异无统计学意义(P>0.05)。A组术后面部肿胀发生率为6%、面部瘢痕发生率为0，B组分别为47%、100%，A组并发症的发生率明显低于B组，两组比较差异均有统计学意义(P<0.05)。A组患者满意度为82%，B组为59%，A组明显优于B组，两组比较差异有统计学意义(P<0.05)。

结论：鼻内镜下泪囊鼻腔吻合联合硅胶管置入术安全性高，损伤小，且术后并发症少，患者满意度高，是治疗慢性泪囊炎合并上泪道阻塞比较理想的手术方法。

METHODS: Totally 68 cases(68 eyes)of chronic dacryocystitis with upper lacrimal duct obstruction were enrolled. They were randomly divided into Group A and Group B through random number table method, each group of 34 cases, Group A was treated with nasal endoscopic dacryocystorhinostomy combined with silicone tube implantation. Group B was treated with traditional dacryocystorhinostomy combined with silicone tube implantation. All patients were followed up for 1a.

RESULTS: In Group A, the total success rate was 82%, that in Group B was 79%. There were no significant difference between two groups' total success rate(P>0.05). The incidence of postoperative facial swelling in Group A was 6%. The facial scar incidence rate was 0. Those of Group B were 47% and 100%. The incidence of complications in Group A was significantly lower than that in Group B with significantly difference(P<0.05). Rate of patients' satisfaction was 82% in Group A, and 59% in Group B, which of Group A was significantly better than group B(P<0.05).

CONCLUSION: Canalicular intubation combined dacryocystorhinostomy using endoscopy is an ideal method in treatment of chronic dacryocystitis with upper lacrimal duct obstruction. It is safe, effective with less injury and less complication.
