This bone prevents structures within the ear from working properly and causes hearing loss. For some people with otosclerosis, the hearing loss may become severe. How do we hear?

Double ring cochlea or Halos sign COCHLEAR OTOSCLEROSIS Isolated pure sensorineural hearing loss without a conductive component CRITERIA FOR DIAGNOSIS OF Otosclerosis, which affects more than three million Americans, is caused by an abnormal growth of sponge-like bone in the middle ear. Many cases of otosclerosis are thought to be inherited. It affects approximately 10% of the adult Caucasian population but is rare in African Americans. Otosclerosis can affect patients at any age and generally worsens with time.

Is otosclerosis inherited? About 50 percent of patients with otosclerosis have a family history of otosclerosis. As otosclerosis spreads to involve the entire stapes, an increase in mass compounds the progressive increase in stiffness, resulting in (1) progression of loss in the high frequencies, (2) a gradual widening of the air-bone gap, and (3) a flat audiogram configuration.

The first step in a diagnosis is to rule out other diseases or health problems that can cause the same symptoms as otosclerosis. Next steps include hearing tests that measure hearing sensitivity (audiogram) and middle-ear sound conduction (tympanogram). Sometimes, imaging tests—such as a CT scan—are also used to diagnose otosclerosis.

An audiogram and tympanogram can be used by an audiologist or otologist to determine the degree of hearing sensitivity and conductivity. A CT scan can give a definitive diagnosis of otosclerosis by showing the level of bone overgrowth which would differentiate this disorder from other causes of hearing loss. Dr. Ted explains Otosclerosis. Visit www.nexgenhearing.com for more information. The audiological signature pattern of fenestral otosclerosis include the following: Conductive hearing loss with Carhart’s notch at 2KHz.
