What are the symptoms of Otosclerosis?

The typical patient with otosclerosis presents with a history of slowly progressive hearing loss that is usually bilateral but asymmetric. Because of its insidious onset, the patient is often unaware of the hearing loss until it is brought to his or her attention by friends or family.

The disease may remain confined to one particular ear; the other ear may become involved later. Hearing loss typically becomes apparent when the loss reaches 25-30 dB and the patient has difficulty understanding speech. Patients characteristically have low-volume (soft) speech because they hear their own voices by bone conduction and consequently talk quietly. The ability to hear better in noisy surroundings (paracusis) during the early stages of hearing impairment is highly suggestive of otosclerosis. Tinnitus is a common complaint and may be an indication of sensorineural degeneration.
