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 protocols could enhance the accuracy, precision, and safety of cochlear implantation procedures, optimize overall patient care, increase success rates, minimize complications, improve long-term rehabilitation, significantly enhancing quality of life, and result in better functional outcomes, psychological well-being, and long-term improvements post-implantation.
