Abstract
Introduction: Currently pre-operative CT scanning of the temporal bones forms part of the routine adult cochlear implantation assessment. The case for post-operative CT scans is emerging.In order to establish the influence CT scans had on implantation decisions, a retrospective analysis of the pre-operative CT findings in adult CI patients was undertaken.Methods: 175 consecutive pre-operative CT scans were reviewed.Results: 25 of 175 scans (14%) showed an abnormality. Only 3 of 175 (1.7%) scans demonstrated abnormalities that influenced the side of implant or decision to implant.Conclusion: More focused use of pre-operative CT scanning may reduce unnecessary scans and allow further utilization of post-operative CT imaging.
