[Use of YAG-ND laser in the treatment of not healing trepanation cavities after cleansing surgery of the middle ear].

Not healing trepanation cavities after middle ear surgery were exposed to YAG-Nd laser radiation (1.06 and 1.32 mk). Persistent epidermization and discontinuation of the discharge were achieved in 72% of the patients with postoperative otorrhea. Optimal regimens of laser radiation (wave length, exposition, power) are detailed for various forms of the pathological process.
