PURPOSE: To evaluate the usefulness of a hook developed for pulling out the guide wire in nasolacrimal balloon dilatation and stent placement. MATERIALS AND METHODS: The head was made of stainless steel wire in ashape of a question mark, and the body was made of four stainless steel pipes. The head was attached to the body in three different ways : A) the head was anterior to the body, B) the head was posterior to the body, and C) the head was angled of 30 ° forward from the direction of the body. 90 epiphora patients took part in a test tocompare and evalvate the usefulness of different types of hook. Average number of trials, success rate and average time of the procedure were recorded. RESULTS: The average trial number for different attachment methods A, B, andC was 4.5, 6.4, and 2.5, respectively, and the success rate 83, 70, and 97%, respectively. The average time of the procedure was 31 minutes. CONCLUSION: The C type hook was the most effective, and the new technique using the hook was more convenient and time-saving than the old technique using a nasal endoscopy.
