Abstract

SNHL in children is an important issue. Cochlear implant is a highly technological device that is surgically inserted in the cochlea to solve this issue. To evaluate types of anomalies of the inner ear in children with sensorineural hearing loss in a tertiary care hospital and confirm that the routine MRI, MR cisternography and HRCT provides the surgeon with the imaging finding and criteria of patients candidates for CI. Patients and method: 600 patients with SNHL underwent HRCT and MRI. CT examinations were normal in 457 patients (76.2%) and 143 patients (23.8%) with inner ear anomalies. MRI examinations were normal in 440 patients (73.3%) and had inner ear anomalies in 160 patients (26.7%). 3D bFFE and 3D DRIVE was summarized. The 3D bFFE sequence was statistically significantly better than the 3D DRIVE for the demonstration of the cochlear vestibule. Superior, inferior vestibular nerves and facial nerves while 3D DRIVE is superior to 3D bFFE in the visualization of the semicircular canals. HRCT and MRI provide accurate anatomical delineation of complex inner ear structures and 3D improves pre-implant evaluation.
