A case of bilateral transverse temporal born fracture is reported. When this patient was first sent to our clinic by a neurosurgeon, the cause of his bilateral cochleovestibular paralysis was not known. In addition to our routine otoneurological examination, the new diagnostic methods of FCR (Fuji Computed Radiography), high resolution CT, MRI (Magnetic Resonance Imaging) were applied. They led us to the final diagnosis of bilateral labyrinthine fracture. Thus, these new methods, especially MRI, are expected to be of help not only to the diagnosis of temporal bone fracture but also in that of dysequilibrium in general.
