AIM: To discuss the common problems and treatment countermeasures in dacryocystorhinostomy under nasal endoscope.

METHODS: The clinical data of 37 cases(43 eyes)of postoperative dacryocystorhinostomy under nasal endoscope, by using high-frequency electric knife to open the nasal mucosa, hemostasis in surgery, burning fixed lacrimal sac mucosal flap and nasal mucosal flap, methylene blue staining of the lacrimal sac, lacrimal drainage tube implanted and expansion foam support fixed anastomotic methods were reviewed in our hospital from Mar. 2011 to June. 2013. The effects of surgery were observed, and the intraoperative common questions and the treatments were discussed.

RESULTS: In the 37 cases(43 eyes), 42 eyes(97.7%)were cured, and 1 eye was improved, and the total efficiency was 100%. All operations were successfully completed without any serious complications during surgery.

CONCLUSION: The common complication in dacryocystorhinostomy under nasal endoscope are effectively treated and the success rates of surgery are improved, by using high-frequency electric knife to open the nasal mucosa, hemostasis in surgery, burning fixed lacrimal sac mucosal flap and nasal mucosal flap, methylene blue staining of the lacrimal sac, lacrimal drainage tube implanted and expansion foam support fixed anastomotic methods. These methods are worthy of application and promotion.
