Abstract

Dacryocyst iodized oil opacification CT scan should be performed. Surgical stoma location is about 1. 5-2. 0 mm above and slightly anterior to the insertion of the middle turbinate. A localization method based on inner canthus ligament shows a high accuracy. The common canaliculus entry point is comparatively permanent, a laser optical fiber should be used for lacrimal passages exploration on the surgery, and the light spot directed toward lacrimal bone on the nasal lateral wall is exactly as an identification marker.
