title: Changes of internal auditory meatus.
abstract: Forty-seven patients with 48 nonoperated acoustic neuromas have been studied by computed tomography (CT) with respect to bone changes. CT and conventional X-ray examination of the skull were compared. The importance of using a small collimator, proper selection of the plane of the CT section, and changing of the window level is stressed. CT detects porus changes as accurately as conventional X-ray methods.
