The audiogram will reveal a "reverse-slope" pattern, where the line on the graph Low-frequency conductive hearing loss from otosclerosis can generally be
The ART pattern is identical to the cochlear pattern but the response is more likely to be absent in a vestibulocochlear nerve pathology or unusually elevated compared with normative values for cochlear hearing loss. Otosclerosis is a disease of the otic capsule. In its active phase, known as otospongiosis, highly vascular lesions resorb bone surrounding the inner ear, most often in a patchy pattern. 2014-02-25 · Otosclerosis ENT 1. 1 OTOSCLEROSIS Salar Alam M10011 2. 2 Outline • • • • • • Related Anatomy Pathogenesis Clinical features Diagnosis Treatment Complications 3. 3 4.
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 audiogram The audiogram with worse air-conduction thresholds at low frequencies, below 1-2 kHz, is typical for otosclerosis 1). Sometimes, in an audiogram with a drop in bone-conduction thresholds at 2 kHz, a “notch” is noted describing a decrease in cochlear sensitivity.
Otosclerosis is a disease that is unique to the otic capsule of humans. The cause is believed to be largely genetic with an autosomal dominant pattern of inheritance, although there is great variability in penetrance and expression of symptomatic disease.
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. Degree of hearing loss Degree of hearing loss: • 0‐15 dB WNL • 16‐25 dB Slight • 26‐40 dB Mild

Audiogram typically shows a conductive hearing loss, usually worse at low frequencies. Carhart notch is characteristic of otosclerosis with a characteristic dip at 2000Hz. Audiogram Interpretation As someone new to conducting hearing tests, you might find the process of uncov-ering various types of hearing disorders somewhat mysterious. You might even think that interpreting your first audiograms is like trying to uncover one of the great unsolved mysteries of the world. Although some of the hearing disorders we

Elevated levels of anti-measles antibody has also been reported in perilymph from patients undergoing stapedectomy for otosclerosis as compared to controls.
