Learning objectives 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...
Read more Background This retrospective study included 15 pediatric patients (aged 8months- 3years) diagnosed with SNHL who had previously undergone CT scanning. In these cases, the CT findings were either inconclusive or did not provide sufficient information for precise cochlear implantation planning. Each patient subsequently underwent high-resolution 3T MRI using a specialized protocol, including 0.4mm CISS/FIESTA sequences to enhance the visualization of the cochlear nerve and inner ear structures. The goal was to determine whether MRI provided additional critical information that could impact...
Read more Findings and procedure details MR imaging provided crucial additional information in 11 out of 15 cases, leading to better-informed preoperative planning. Specifically, MRI identified cochlear malformations in six patients, including two cases of common cavity malformation and four cases of incomplete partition of the cochlea. Additionally, three patients were diagnosed with vestibulocochlear nerve hypoplasia, which was not apparent on CT scans. In the remaining cases, no significant inner ear abnormalities were found; however, focal changes in brain white matter, consistent with periventricular leukomalacia (PVL),...
Read more Conclusion High-resolution 3T MRI demonstrates superior sensitivity for soft tissue evaluation, particularly in cases of suspected cochlear nerve deficiency and intracranial abnormalities. As a safe, radiation-free imaging modality, MRI offers a highly informative complement to CT for preoperative assessment. Its ability to provide detailed visualization of the cochlear nerve and inner ear structures supports its use in optimizing surgical planning and improving cochlear implantation outcomes in children with SNHL. The findings of this study suggest that integrating MRI into routine preoperative...
