Abstract

Objective The aim was to evaluate the role and efficacy of high-resolution computed tomography (CT) scan after cochlear implantation in evaluating the integrity and insertion of the electrode, whether complete or incomplete, whether intracochlear or extracochlear, and whether to change the decision for revision or not. Sitting The study was conducted at the Hearing and Speech Institute. Patients and methods All the patients 300 cases undergo CT scan radiology within one week postoeratively and reevaluated for electrode insertion. Complete, incomplete, or over insertion. intracochlear or extracchlear. Results This study was carried out on 312 cases from January 2019 to December 2020. Age ranged from 1.2 to 64 years, with a median age of 9.7 years. The number of children under the age of 18 was 254 cases, with a median age of 4.3, and the number of cases above 18 years was 58 cases, with a median age of 33.6 years. The right ear was implanted in 280 cases. Male patients represented 152 cases, and female patients represented 148 cases. Postoperatively CT scan showed two cases with major complication (extracochlear insertion) that required revision surgery. A total of 290 cases had standard insertion, five cases showed one electrode extracochlear, and three cases showed overinsertion, with no intervention performed. Conclusion The radiograph only affects the decision making and patient management. CT high-resolution is mandatory after cochlear implants.
