[The role of audiological methods of investigation in diagnosis and treatment of chemodectomas and hemangiomas of the middle ear].
Diagnostic value of some audiological methods of investigation (pure-tone audiometry, tympanometry, noisimetry) has been determined on the basis of examination and treatment of 114 patients with chemodectoma and hemangioma of the middle ear. Tympanometric evidence directly correlated with primary location and dissemination of the tumor. Changes on tympanograms and noisimetries correlate with the results of the tests with pressure of the neck's vessels and elevation of airpressure in the external acoustic meatus. Audiological findings are comparable with those of CT and MRT of the temporal bones and visualization of the tumor in surgery. High significance of the above methods was proved.
