Abstract
The labyrinth necrosis has become a rare disease since the antibiotics and the chemotherapeutics appeared. The author reports a case of labyrinth necrosis. The patient was a 14-year-old boy who was given a radical operation of the left middle ear cholesteatoma otitis. The labyrinth necrosis was found during the operation. No disturbance of equilibrium was observed, probably because the formation of necrosis of the labyrinth was very slow.
