Abstract

The purpose of the study was to obtain reference values for the sizes of anatomical structures of the inner ear on computed tomography CT images and to compare these values with those obtained from patients with Menière’s disease CT images of the temporal bone of 67 patients without inner ear pathology and 53 patients with Menière’s disease have been evaluated CT was performed in the sequential mode 1mm slice thickness 120 kV 125 mA Anatomical structures such as the length and the width of the cochlea and of the vestibule the height of the basal turn the length and the width of the cochlear the vestibular and the singular aqueduct and the internal auditory meatus and the diameter of the semicircular canals were measured using a dedicated postprocessing workstation Reference values from the control group could be obtained In the patients with Menière’s disease the length and the width of the vestibular aqueduct were smaller compared with the values from the control group The values obtained from the control group can serve as reference values for adult patients The different sizes of anatomical structures of the control group and of patients suffering from Menière’s disease suggest that functional impairment might be related to subtle morphological changes
