We report here the temporal bone histopathology of a 50-year-old woman who died of renal insufficiency due to diabetes mellitus. She had complained of profound deafness of both ears and dizziness. She had no caloric response, and spontaneous nystagmus towards the left was observed 20 days before death.
The temporal bone findings indicated typical bacterial labyrinthitis. Infectious changes indicated typical bacterial labyrinthitis. Infectious changes invaded the cochlea through the round window and destroyed the cochlea. The pathology of the left ear was greater than that of the right ear. These inner ear changes correlated well with auditory and vestibular function tested before death.
