Otosclerosis can affect patients at any age and generally worsens with time. After a patient undergoes a hearing test or audiogram, an otolaryngologist can determine if a patient has otosclerosis and if it can be treated. On rare occasions, a patient may develop cochlear otosclerosis, which is a progressive and irreversible hearing loss.

The most common age group presenting with hearing loss from otosclerosis is obliterated footplate or obliterative otosclerosis. Tests- Pure tone audiometry.
