Abstract

To assess the imaging findings of computed topography (CT) and magnetic resonance imaging (MRI) in adults with postlingual deafness and otherwise normal clinical history and physical exam. Additionally, determine the influence and implications of these findings with respect to surgical outcomes and cost. Retrospective case review. Tertiary referral hospital. Adults with postlingual deafness with no history of prior ear surgery, chronic ear disease, meningitis, otosclerosis, or head trauma. Cochlear implantation of 1 or both ears, with preoperative CT, MRI, or both. Imaging results were classified as normal, abnormal affecting surgery, incidental requiring follow-up, or incidental not requiring follow-up. Average cost of each imaging modality was determined. A total of 128 patients met the inclusion criteria. Of these, 82 (64.1%) had both CT and MRI performed, 33 (25.8%) had CT, and 13 (10.2%) had MRI prior to cochlear implant (CI). Scans were normal in 125 (97.7%) of cases. Of the remaining 3 (2.3%) patients, there were incidental findings requiring follow-up. All implants were placed successfully, and in no instance did the results of the scan influence the surgery. The average cost of imaging per patient was $4707. In adults ...Continue Reading
