Answer Explanation: If AOM recurs and there is no contraindication, a ventilating, or pressure-equalizing, tube may be inserted. The ventilating tube, which temporarily takes the place of the eustachian tube in equalizing pressure, is retained for 6 to 18 months. Ossiculoplasty is not used to treat AOM and stapedectomy is performed to treat otosclerosis. Cochlear implants are used to treat sensorineural hearing loss.
