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 …

13 Oct 2005 Audiometry revealed mixed conductive and sensorineural hearing loss, more on the left side than on the right side. The patient's daughter was

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? Also I realize it causes SNHL, but what sort of damage does it do to the Inner ear?

Degree of hearing loss Degree of hearing loss: • 0‐15 dB WNL • 16‐25 dB Slight • 26‐40 dB Mild 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 otoscopy, there are usually minimal or no findings, except in severe cases where cochlear involvement can result in hyperemia of the cochlear promontory ( Schwartze sign ) 1-3. On pure-tone audiometry, there may be a characteristic decrease in bone conduction at 2000 Hz (Carhart notch). The authors think that in otosclerosis surgery the accurate measurement of cochlear function must be made according to 4 local factors, to which must be added a 5th, general one. 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.

4 In such cases, it has been suggested that toxic substances (proteolytic enzymes) reach the endosteal cochlear capsule through small 2019-09-26 2001-05-29 Cochlear implantation is rarely a treatment option and often comes only after unsuccessful otosclerosis surgeries. A cochlear implant (CI) is an electronic device that partly brings back sensorineural hearing loss.

In cochlear otosclerosis, the audiological pattern is one of end organ disease. The Békésey audiogram is usually a type 2. There is a moderate tone decay of up to 20 dB. Speech discrimination scores of 80 to 90% are typical of cochlear otosclerosis.

Pure tone audiogram: mild-to-severe sensorineural hear-ing loss in the left ear. In the IAC diverticulum and otosclerosis group, there were 7 patients with 12 affected temporal bones.

The authors think that in otosclerosis surgery the accurate measurement of cochlear function must be made according to 4 local factors, to which must be added a 5th, general one. 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

In clinical practice, cochlear otosclerosis can also be observed. The audiological signature pattern of fenestral otosclerosis include the following: Conductive hearing loss with Carhart’s notch at 2KHz. Excellent speech discrimination scores ( Also seen in cochlear otosclerosis) Low compliance on Impedance (immitance) audiometry ( less than 0.3cc) Seen in fenestral as well as cochlear otosclerosis. – 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 Otosclerosis audiogram The audiogram with worse air-conduction thresholds at low frequencies, below 1-2 kHz, is typical for otosclerosis 1) .

We examined the effectiveness of sodium fluoride in treatment of cochlear otospongiosis in ninety-four patients with cochlear otosclerosis and ninety-eight patients with stapedial otosclerosis and sensorineural hearing loss. The drug halted or slowed the progression of sensorineural hearing impairment in 63% of the patients with cochlear Otosclerosis can affect patients at any age and generally worsens with time.
