When pure stapedial otosclerosis is present, the most prominent audiologic signs are elicited in response to the use of low-frequency stimuli, reflecting the effect that increased stiffness has on the transfer function of the middle ear. Characteristic abnormalities appear on tympanometry, acoustic reflexes, and the pure-tone audiogram. Following are some methods to diagnose Otosclerosis: 1.

Generally, audiograms in patients with otosclerosis initially show low-frequency conductive hearing loss. High frequencies typically are unaffected at this stage. This characteristic audiogram configuration has been referred to as stiffness tilt.
