[Experience with the clinical use of laser surgery in the nasal cavity].

The authors treated nasal bleedings of various origin, lower turbinate hypertrophy, nasal polyps and rhinolithiasis using different, kinds of surgical lasers for the first time in Hungary. According to their experiences the modern CO2 and Nd-Yag laser with advanced optics are applicable for the purposes of endonasal laser surgery. The use of CO2 laser is indicated for vaporization and cutting of small haemorrhagic areas without strong bleeding, Nd-Yag laser is more suitable for coagulation and vaporization of highly vascularised tissue masses. The, fiber optic introducible into the endoscope makes the Nd-Yag laser useful for almost every endoscopic nasal and paranasal surgery, making simultaneous video-documentation possible. Using lasers combined with endoscopes (in itself or as an independent step of operation) is a method with minimal operational stress and invasivity, which makes effective surgery possible, in many cases as one-day surgery.
