Figure 4–1 Pure tone audiogram of a patient suffering from cochlear otosclerosis. The multiple sloping pattern gives it the appearance of a cookie bite. Dotted line = bone conduction. Solid line = air conduction. The audiologic manifestations of otosclerosis are as distinctive as they are varied. 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.

The pure-tone audiogram gives the diagnosis of the stage of deafness. Accurate bone conduction (BC) must of course be researched with a contralateral narrow-band masking when there is the slightest difference between 2 air-conduction (AC) diagrams, as well as between the 2 BC diagrams. I recently came across an article discussing a person with the diagnosis of Cochlear Otosclerosis? Exactly what does the diagnosis of Cochlear Otosclerosis entail? I am assuming a person must have Otosclerosis of the middle ear first in order to get Cochlear otosclerosis?

Cochlear otosclerosis is otosclerosis located in the otic capsule involving the cochlear endosteum and causing sensorineural hearing loss; Evidence supports the thesis that clinical otosclerosis has an autosomal dominant tendency with incomplete penetrance; Chronic measles infection in bone can predispose patients to otosclerosis.

This finding, in addition to an absent acoustic reflex, is generally thought to be diagnostic of otosclerosis. Some patients will have a high-frequency sensorineural hearing loss due to involvement of the cochlea, termed cochlear otosclerosis. However, other conditions can cause the same type of audiologic profile. Cochlear Otosclerosis When otosclerosis spreads to the inner ear a sensorineural hearing impairment may result due to interference with the nerve function.

Introduction:Otosclerosis is a bone dysplasia of the optic capsule that promotes progressive metabolic derangement, and can lead to profound hearing loss. Aim:Compare the postoperative results in patients undergoing cochlear implant with otosclerosis compared with patients with other causes of deafness Design: Retrospective cohort study.

History: Otosclerosis was first described in 1735 by Valsalva as ankylosis of the stapes to the margins of the oval window. 2017-03-25 Otosclerosis begins in endochondral bone, as the spongious and sclerosis continue the endosteal and periosteal layers also become involved (Roland and Samy, 2006). The clinical presentation of otosclerosis is mainly a conductive hearing loss, although sensorineural hearing loss, and mixed hearing loss may also occur.

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.

On occasion the otosclerosis may spread to the balance canals and may cause episodes of unsteadiness. Audiograms, in addition to medical history and physical examination, have traditionally been used for diagnosis of otosclerosis.

Introduction Otosclerosis is per-se a disease of the otic capsule and can arise from different sites in the otic bone, the commonest sites being fissula ante fenestrum (40%) and fossula post fenestrum (25%). Otosclerosis can affect patients at any age and generally worsens with time.
