Vestibular compensation in vestibular neuronitis: evaluation of positional nystagmus and caloric nystagmus.

We evaluated the vestibular functions, especially for positional nystagmus and caloric nystagmus, in 43 cases of vestibular neuronitis for long periods after its onset. It is shown that in the cases of vestibular neuronitis that were studied more than 10 years after the onset of the disease, the completed vestibular compensation changed or the vestibular compensation was still incomplete.
