On an audiogram, patients with otosclerosis commonly have conductive hearing loss with a drop in the bone-conduction threshold at 2,000 Hz, called a Carhart notch. This finding, in addition to an absent acoustic reflex, is generally thought to be diagnostic of 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.

After a patient undergoes a hearing test or audiogram, an otolaryngologist can determine if a patient has otosclerosis and if it can be treated.

Otosclerosis audiogram pattern

Pattern recognition can also help guide inter-pretation of the remainder of the audiogram data. These patterns can extend to the associated immit-tance and speech testing. For example, patients with otosclerosis will have a conductive hearing loss noted in the involved ear. Classically, there is an isolated increase in the bone conduction thresh- Otosclerosis, also known as otospongiosis, is a primary osteodystrophy of the otic capsule (bony labyrinth of the inner ear). It is one of the leading causes of deafness in adults. Terminology The term otosclerosis is somewhat of a misnomer.

In fact, women with otosclerosis in both ears felt they experienced a 33 percent decline in their hearing after a single pregnancy, one study found. An audiometric finding characteristic of otosclerosis is an increase in bone conduction threshold with a peak at 2,000 Hz known as Carhart's notch (Carhart, 1950). Although the notch occurs at 2,000 Hz, a reduction in bone conduction sensitivity is seen from 500 to 4,000 Hz which is, on average, 5 dB at 500 Hz, 10 dB at 1000 Hz, 15 dB at 2000 Hz, and 5 dB at 4,000 Hz (Carhart, 1971). 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. BACKGROUND AND PURPOSE: Focal low-attenuation outpouching or diverticulum at the anterolateral internal auditory canal is an uncommon finding on CT of the temporal bone.
