Two cases of brain tumors and a case of otosclerosis were reported, and these pre・operative neuro-otological analyses were discussed in comparison with the surgical findings, in order to evaluate the diagnosis of the lesions in the acoustic pathways and the vestibular system by the neuro-otological analyses which were exceedingly advanced in the past ten years. It is considered that the auditory analyses namely with an impedance audiometry were now quite useful in the diagnosis of otosclerosis, moreover, the neuro-otological combinating analyses for the acoustic pathways and the vestibular system, i.e. acoustic reflexes in an impedance audiometry, optokmetic nystagmus test, eye tracking test, etc., were very important to diagnose the brain tumors. |
