Abstract

Objective: To assess the role of imaging using High resolution computed tomography and Magnetic resonance imaging temporal bone for evaluating candidates for cochlear implantation.

Methodology: It was a prospective study conducted in the department of Otorhinolaryngology at a tertiary care centre 30 children up to 5 years of age with severe to profound sensorineural hearing loss, radiological evaluation using HRCT and MRI temporal bone was done in all children.

Results: 20(66.67%) were in 2-4 years age group with female preponderance. Radiological abnormalities were reported in 13(43.33%) children. Abnormalities of inner ear were seen in 8(26.67%) cases, which included bilateral cochlear nerve aplasia, unilateral cochlear aplasia with bilateral cochlear nerve aplasia, bilateral severe cochlear hypoplasia, mondini’s dysplasia. Cochlear nerve deficiency was found in 3(10%) children and narrow Internal auditory canal in 4(13.33%) children.

Conclusion: Imaging is a fundamental part of the preoperative workup for CI, HRCT and MRI temporal bone are complementary to each other in evaluating children for CI as HRCT is excellent for demonstrating bony details but, lack in providing details of inner ear neural structures and MRI is better than CT in demonstrating vestibulocochlear nerves.
