| Popis: | Objective: To assess the diagnostic reliability of MDCT in pre-operative evaluation of cochlear implant candidates and post-operative, estimation of depth of insertion. Material and methods: The study includes 40 patients (18 males and 22, females); classified into 2 groups: group A (20 patients): cochlear, implant device was Nucleus-22. Group B (20 patients): device was MED-EL.Cochlear length (CL) and cochlear height (CH) were measured pre-operatively by 128-multidetector CT. Electrode length (EL) and insertion, depth angle (α) were measured post-operatively by MDCT. Results: Group A: mean CL was 9.1 mm ± 0.4 SD; mean CH was 4.1 ± 0.3 SD; mean EL was 18 ± 2.7 SD; mean α angle was 299.05 ± 37 SD. Significant, statistical correlation (P |
