Audiogram otosclerosis Fig 7: Otosclerosis: conductive hearing loss with a bone conduction dip at 2kHz - 'Carharts Notch' Audiogram Noice induced hearing

Otosclerosis cannot be seen on an office examination. The audiogram indicates a conductive type of hearing loss. A special type of testing, stapedial reflexes, indicates limited or no movement of the bones of hearing. Is otosclerosis inherited? About 50 percent of patients with otosclerosis have a family history of otosclerosis.

Audiogram otosclerosis

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. Diagnostic audiologic procedures for otosclerosis are effective tools in identifying this condition. Audiometric data usually demonstrate a conductive hearing loss at the early stages of otosclerosis.

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.

Audiometry is a necessary tool to confirm and document the presence of otosclerosis. Otosclerosis presents in a unique and typical way. Pure stapedial otosclerosis has its unique signature which can be recognized on pure tone and impedance audiometry.

Om det finns misstanke om otoskleros remitteras man till en öron-näsa-hals specialist som kan genomföra ytterligare undersökningar för att fastställa diagnosen.

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. – Describe the audiogram by configuration from least amount of hearing loss to the most (ex: mild to severe) – Pure tone average is 500 Hz, 1000 Hz, and 2000 Hz added and divided by 3.

Otosclerosis results in an audiogram with significant loss at all frequencies, often of around 40 dB (HL). A deficiency particularly around 2 kHz (termed a Carhart notch in the audiogram) is characteristic of either otosclerosis or a congenital ossicular anomaly. Ménière's disease results in a severe loss at low frequencies.

Characteristic abnormalities appear on tympanometry, acoustic reflexes, and the pure-tone audiogram. Diagnostic audiologic procedures for otosclerosis are effective tools in identifying this condition. Audiometric data usually demonstrate a conductive hearing loss at the early stages of otosclerosis. Modern middle ear analysis procedures are becoming more popular in the better diagnosis of otosclerosis.
