Staged resection of large acoustic neuromas.

Objective: Surgical removal of large (>3 cm) acoustic neuromas is associated with poor long-term facial nerve function results and higher complication rates. This study analyzes whether long term facial nerve function and the incidence of neurological and vascular complications is improved by resection of large acoustic neuromas in 2 or 3 stages.

Patients And Methods: Among 660 patients who underwent surgical resection of acoustic neuromas between 1989 and 2002 by the senior author (J.

The Chiari I malformation and the neurotologist.

Objective: The first objective of this paper is to report the clinical symptoms of 77 patients and the results of their neurologic, vestibular, and audiological evaluations done with magnetic resonance imaging, which confirmed Chiari I malformations. The second objective is to report how the results of a vestibular evaluation can help neurosurgeons decide on the need for surgical treatment.

Study Design: Retrospective chart review of 77 patients seen between 1988 and 2000.
