Abstract
The newly developed holmium: YAG (Ho: YAG) laser was applied to endoscopic endonasal sinus surgery in the viewpoint of a characteristic property of efficient ablation to bone tissues. We applied Ho: YAG laser to inferior turbinectomy (5 cases), marsupialization of paranasal sinus mucoceles (10 cases), and dacryocystorhinostomy (2 cases), which led to successful and satisfactory results. The present results revealed that Ho: YAG laser is useful tool for bone ablation in endoscopi sinus surgery.
