[Frey's syndrome of the external auditory canal].
Frey's syndrome of the external auditory canal is extremely rare. A 55-year old woman presented with a 6 month history of unilateral gustatory otorrhea. She never complained of hearing impairment, tinnitus, vertigo or otalgia. No trauma or surgical signs were evident near the ear or parotid gland. Examination of the ear showed an intact tympanic membrane without disease. A diagnosis of gustatory sweating syndrome was suggested by the observation of sweat production after chewing and by Minor's starch-iodine test. Symptoms were relieved after tympanic neurectomy. The pathogenesis, differential diagnosis and treatment options are discussed.
