发明名称 Method of performing translactrimal laser dacryocystorhinostomy
摘要 A method fo performing dacryocystorhinostomy is provided in which the surgeon inserts a video endoscope into a punctum, through the associated canaliculus and into the lacrimal sac. The surgeon passes a bone cutting laser, connected to a fiber optic bundle, through the other punctum, through the associated canaliculus and into the lacrimal sac. The laser is illuminated through the fiber optic bundle and visualized through the video endoscope. The laser is properly positioned sometime with the help of a transnasal videoendoscope to confirm optimal position relative to nasal structure. The laser is then activated so as to form a full thickness tear draining fistula through the sac and the nasal bone. A tube or stent may be placed to keep the fistula patent or from closure.
