Round window ultrasonic irradiation for Meniere's disease with ENG monitoring.
Utrasonic irradiation of the labyrinth via the round window is effective in controlling otological vertigo. This method of surgical management for incapacitating vertigo is presented with demonstrative intraoperative electronystagmograms and irradiated cat neuro-epithelium. Such data suggest that more intense irradiation doses than previously reported should be applied to effectively destroy the diseased labyrinthine end organs. Precise end points of destructive irradiation are defined by characteristic intraoperative electronystagmograms. The authors suggest this is an ideal procedure when the situation of an unaffected cochlea, coexisting with a diseased labyrinth, requires a minimally invasive, destructive procedure which preserves hearing while eradicating vertigo.
