[Early detection of the neurosensory component of hearing loss in patients with adhesive otitis media].
Thirty patients with adhesive otitis media and 10 otologically normal subjects were examined audiometrically in a wide frequency range according to Sagalovich. It was found that this kind of audiometry may help detect early symptoms of hearing impairment on a neurosensory basis which remain unobservable in conventional audiography. It was demonstrated that hearing threshold increments in a wide frequency range correlated with the shape of the curve of bone conductivity in conventional audiography. The hearing changes in a wide frequency range were dependent on the primary disease duration and were independent of the bone-air interval value in conventional audiography. Our investigations allow the conclusion that measurement of hearing sensitivity in a wide frequency range under the conditions of bone conductivity enlarges the capabilities of current tonal audiometry and opens up new perspectives for assessing the hearing level of patients with adhesive otitis media.
