[Laser destruction of labyrinthine receptors as a treatment for benign paroxysmal postural vertigo and otolith symptoms].

Outcomes of surgical laser treatment are presented for 15 patients with resistant to conservative therapy benign paroxysmal postural vertigo (BPPV) and otolith-related disorders. Nine patients with Meniere's disease with BPPV (n=3) and otoliths (in all the patients) were exposed to laser impulses on the bony wall of the horizontal semicircular canal. The impulse was directed in the lumen of the canal in 6 patients with BPPV and otolith symptoms. In Meniere's patients vertigo stopped, hearing was at the preoperative level. Neither threy had BPPV nor otolith problems. The same results were obtained in 6 patients with the other diseases. Vestibular excitability of all surgically treated patients decreased to the fifth degree.
