| Description | Journal: Otology & Neurotology Objective Preoperative evaluation of cochlear implant candidate includes routine imaging to identify anatomic abnormalities that may preclude or complicate implantation, such as cochlear aplasia, absent/narrowed internal auditory canals, cochlear ossificans, or significant traumatic fracture. The aim of this study is to determine if preoperative imaging is necessary in select cochlear implant candidates, thus defraying cost and ionizing radiation. Study Design Retrospective chart review. Setting Tertiary referral facility. Patients Adult patients with progressive sensorineural hearing loss without evidence of head trauma, meningitis, or congenital hearing loss who underwent cochlear implantation. Interventions Diagnostic and therapeutic. Main Outcome Measures Preoperative radiologic abnormalities, deviation from standard cochlear implant operation. Results One hundred eighteen cochlear implants met inclusion criteria; 23.7% of CT scans had a documented abnormality, including chronic otitis media (14.4%), otosclerosis (4.2%), and an enlarged vestibular aqueduct (3.4%). There were 6 eventful surgeries in patients with normal documented CT scan. Events included multiple insertion attempts (3.4%), CSF leak (2.5%), and no apparent round window (2.5%). In every case, a cochlear implant was able to be placed successfully. Conclusion In the appropriately selected patient, preoperative imaging is not necessary as it does not impact the cochlear implant surgery and will defray cost and ionizing radiation. |
