PURPOSE: To evaluate the technique of dacryocysthorrinosthomy for the treatment of nasolacrimal duct obstruction, by transnasal endoscopic video-assisted approach with Nd:YAG laser and diode laser. METHODS: Fifty one surgeries dacryocysthorrinostomy transnasal endoscopic video assisted were performed in 42 patients, 36 females, 6 males, aged between 3 and 92 years, mean age 52.3 years, in the period of April 1997 to February 2003. RESULT: The surgery successfully relieved lacrimal duct obstruction in 92.15% of the patients. CONCLUSION: The technique was efficient for the treatment of nasolacrimal obstruction. In all patients bicanalicular silicone stents were inserted at the time of surgery and removed after six to eight weeks. There is no difference in the results between Nd:YAG and diode laser. The postoperative period in all cases was comfortable and there was no hemorrhage.
