ABSTRACT OBJECTIVE: To evaluate the thermal effects of a 970 nm diode laser and select the modes necessary for the safe and effective use of this laser to reduce the nasal septum elevation (NSB) in volume in vitro. MATERIAL AND METHODS: Laser exposure was carried out through a quartz fiber with a diameter of 400 μm in a continuous contact mode at a power from 2 W to 10 W with a step of 2 W. Three linear cuts 1 cm long were applied to the specimens. The distance between the cuts was 0.5 cm. The initial temperature of the fragments was 25.6±1.6°C. Temperature control was carried out from the side of the fragments opposite to the laser action using a certified and verified thermometer with a contact sensor. RESULTS: In the course of the experiment, it was noted that the optimal power for effectively and safely reducing the area of the nasal septum el evation is 4 W. The maximum heating temperature reached 38.6±4.7°C. CONCLUSIONS: A semiconductor laser with a wavelength of 970 nm can be used to reduce the elevation of the nasal septum, as it leads to predictable results, allowing you to control thermal effects and damage to surrounding tissues.
