title: [Objective audiometry in diagnosis of tinnitus].
abstract: During last 3 years there have been 900 tinnitus patients treated at ENT Rehabilitation Center in Poznan. Everyone underwent a thorough laryngological and audiological examination. Diagnostic procedure comprised also neurological and endocrinological consultations with accessory blood tests. Wide group of audiological tests used for diagnosis was divided into objective (BERA, OAE, tympanometry, stapedius reflex) and subjective (pure tone audiometry, speech audiometry, suprathreshold audiometry) methods. Otological diagnostic in tinnitus patients is difficult due to its subjective character. That is why it is so important to have objective methods for its evaluation. In this paper authors present results of BERA tests and impedance conducted on group of 900 patients. Performed objective tests enabled to diagnose otosclerosis, chronic otitis media and pathology in cerebello-pontine angle in patients without any abnormalities on physical examination.
