Do Inner Ear and Mastoid Bone Structural Variations Have a Determining Role on Vestibular Symptoms of Migraine?

Abstract

Aim:To investigate the possible relationship between morphological changes caused by anatomical structural differences and functional impairment in Vestibular migraine (VM) and Chronic Migraine (CM) disease.Methods:A total of 44 patients (VM group; 23 and CM group; 21) included in the study. The medical records of patients with CM and VM between 2016-2018 were retrieved from the digital database of the otorhinolaryngology and neurology clinics. The mastoid bone and inner ear measurements in temporal bone high resolution computed tomography and inner ear magnetic resonance imaging were performed in our study. The two groups were compared radiologically.Results:Right cochlear height in the VM group was significantly higher than the CM group. The left vestibular height in the VM group was significantly higher than the CM group.Conclusion:The reason why not all patients with CM have vestibular complaints may be due to some differences in the inner ear anatomical structure.
