Summary: | Background Cochlear implant surgery is an invasive procedure for patients with bilateral Sensorineural hearing loss and may cause some risks such as cochlear damage. We aimed to evaluate the effectiveness of cochlear measures obtained by computed tomography (CT) scan in predicting depth of cochlear implant insertion. Materials and Methods This study was conducted in a retrospective and cross-sectional study on 39 patients undergoing cochlear implantation with MED-EL Device. High-resolution radiographs provided preoperative by CT-Scan were used to determine electrode array insertion depth and diameter of the cochlea’s basal turn. The insertion was considered deep when the electrode was placed at least 22 mm into the cochlea. Demographic data, CT-Scan results and cochlear implantation outcomes (deep or shallow) were evaluated. Data were analyzed by SPSS22 software and the significance level was less than 0.05. Results The mean age of patients was 8.026±1.77 years. The depth of insertion of the electrode in 34 (87.18%) patients was deep and in 5 (12.82%) patients was shallow that the difference was statistically significant (P |
