Stereotactic radiation treatment, also known as gamma knife surgery or radiosurgery, has come into acceptance as a treatment alternative to surgical removal for posterior fossa tumors. The purpose of this article is to describe the role of the neurotologist in the optimal management of neurotologic complications after stereotactic radiation, as illustrated by five patients. ⋯ Stereotactic radiation of posterior fossa tumors can produce significant neurotologic problems. It is imperative that neurotologists remain involved in the follow-up care of patients with posterior fossa tumors to offer optimal treatment alternatives for the neurotologic disorders.

To correlate patient response and recurrence rate after canalith repositioning to clinical presentation and cause of BPPV. ⋯ Canalith repositioning was effective in 99% of patients based on elimination of nystagmus. Partial responders probably experienced resolution naturally over time because of a difference in pathophysiology. Higher recurrence rates can be expected when the cause is thought to involve an ongoing process.
