[Early detection of a sensorineural aspect of hypoacusis in patients with chronic purulent otitis media].

To detect initial signs of internal ear dysfunction in 87 patients with otitis media purulenta chronica (OMPC), wide-rage frequency audiometry (WRFA) in bone and air conduction according to B.M. Sagalovich was used. Most of the patients with normal bone conduction in frequencies up to 8 kHz had higher bone thresholds in wide-range frequencies. In mixed hypoacusis these thresholds rose to the highest degree. A correlation was found between a rise of auditory thresholds wide range of frequencies in bone conduction and the disease duration.
