Morphometric Evaluation of the Facial and Vestibulocochlear Nerves Using MR Imaging in Patients with Menière Disease

Our data found no differences in nerve morphometry between clinically nonaffected and affected sides in patients with unilateral MD, nor any correlation with symptom duration. This finding contrasts with previous ones of correlations between clinical features and endolymphatic hydrops. A disease process starting before clinical symptom onset could be a possible explanation. Morphometric evaluation of brain nerves using hydrops MRI sequences is practical and provides similar results compared with T2-weighted imaging, improving patient comfort and reducing MRI scan times.
