Abstract
Postural vertigo as a result of trauma has been found associated with fractures through the petrous portion of the temporal bone without seriously affecting auditory function. These cracks have sometimes defied identification by X-ray examination. Positional nystagmus in these patients was induced, or was more pronounced in the positions in which the affected ear was undermost. Spontaneous nystagmus and nystagmus induced by positional changes in these patients have had their quick component directed toward the affected ear. Section of the vestibular nerve through an approach through the midcranial has proved to be an effective technic in relieving patients of their postural vertigo. The technic is attended by some risks, particularly to the facial nerve and auditory function. These risks will become less as our experience with the technic grows.
