• The incidence and degree of sensorineural hearing loss were analyzed in 67 patients operated on for adhesive otitis. Median observation time was 11 years. The difference in bone conduction between the treated ear and the untreated ear was assessed for each frequency, before operation and late after operation. A sensorineural hearing impairment of 5 dB was found in the frequency region of 500 to 2,000 Hz and of 10 dB at 4,000 Hz. The hearing did not deteriorate during the postoperative period. In 76% of the patients, the bone conduction in the treated ear compared with the healthy ear was at least 10 dB poorer at one or more frequencies. There are great problems in analyzing sensorineural hearing loss in chronic otitis, which often is or has been bilateral.
