Sensorineural hearing loss (SNHL) is one of the leading causes of childhood disability worldwide. Early diagnosis and intervention, including cochlear implants, are crucial for supporting speech and language development in affected children and optimizing their overall quality of life. CT examination is the preferred diagnostic modality for preoperative planning of affected patients. However, magnetic resonance imaging (MRI), particularly with high-resolution 3T scanners, offers a significant advantage in evaluating soft tissues, including the cochlear nerve and inner ear structures. This study investigates the importance of MRI as a safe, radiation-free diagnostic method for cochlear implantation surgery planning.
