Nine cases of misdiagnosed Bell's palsy were analyzed. The patients had been diagnosed and treated as Bell's palsy, because the facial palsy had occurred suddenly and the clinical course resembled that of Bell's palsy. Three of the patients had neurinoma of the facial nerve, one had congenital cholesteatoma, one had temporal bone metastasis of malignant tumor, three had intracranial tumor and one had temporal bone destruction secondary to otitis media with effusion. The facial palsy was progressive in one case, recurrent in three cases and unchanged in five cases. In eight cases, perceptive or combined hearing loss was observed. Vestibular function disorder was seen in five cases and central nervous system disfunction in three cases. We emphasize that a diagnosis of Bell's palsy should not be made without a careful examination of the ears and central nervous system, including the sense of hearing and vestibular function.
