KTP/532 and holmium: YAG (Ho: YAG) lasers newly developed have been applied to the field of rhinology. We report new aspects of application of both lasers to endoscopoic sinus surgery. Eighty patients with chronic sinusitis and mucoceles underwent KTP/532 laser under endoscopic sinus surgery. KTP/532 laser was demonstrated to provide efficient results with reduction of postoperative polyps and granulation tissues around the enlarged maxillary sinus ostium and an enhanced healing of the extensive polypoid degeneration of the maxillary sinus in patients with chronic sinusitis. However, no significant result was obtained in the postoperative care of the enlarged opening of mucoceles. We applied Ho: YAG laser to endoscopic sinus surgery in view of a characteristic property of efficient ablation to bone tissue. The inferior turbinectomy, marsupialization of paranasal sinus mucoceles, and dacryocystorhinostomy using Ho: YAG laser led successful and satisfactory results. Both KTP/532 and Ho: YAG lasers are concluded to be promising tools for endoscopic sinus surgery.
