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.

Cochlear Otosclerosis. When otosclerosis spreads to the inner ear a sensorineural hearing impairment may result due to interference with the nerve function. This
9 Feb 2010 Otosclerosis classically presents with conductive deafness. However Carhart R , Haynes C: Clinical reliability of bone conduction audiometry. 7 Jul 2009 Speech audiometry gives the functional value of the ear. It must be done in AC and BC; the authors insist on the value of the speech Weber test.
A simple model of the acoustic reflex pathway. The acronyms are as follows: ME = middle ear, IE = inner ear, VIII = vestibulocochlear nerve, CN = cochlear nucleus, SOC = superior olivary complex, VII = facial nerve. Note: (1) two of the structures in the pons (SOC and VII nucleus) are shown together for simplicity.
Otosclerosis can affect patients at any age and generally worsens with time. After a patient undergoes a hearing test or audiogram, an otolaryngologist can determine if a patient has otosclerosis and if it can be treated. On rare occasions, a patient may develop cochlear otosclerosis, which is a progressive and irreversible hearing loss. Otosclerosis affects the endosteal lining of the cochlea and induces ossification of the round window membrane and of the scala tympani. 3 Sensorineural hearing loss has also been shown to occur without direct endosteal involvement by the otospongiotic focus. 4 In such cases, it has been suggested that toxic substances (proteolytic enzymes) reach the endosteal cochlear capsule through small patients with otosclerosis.

CONCLUSION: Stapes surgery is a suitable treatment option for patients with advanced otosclerosis, and should be considered mandatory, before offering cochlear implantation, for those with a demonstrable conductive component to their hearing loss.

In cochlear otosclerosis air conduction thresholds continue to worsen and the loss starts to become mixed or sensorineural, with the high frequencies becoming severely affected. The typical pattern of cochlear otosclerosis in the early stages is the “cookie bite”pattern where the greatest degree of hearing loss occurs in the mid-frequency hearing range and is characteristically a mixed hearing loss.

The sensorineural hearing loss of the affected parts of the cochlea was determined by the last antemortum bone conduction audiogram available. There were eight temporal bones with only stapes footplate involvement, six with one discrete focus of otosclerotic endosteal involvement, and 15 with two or more foci of endosteal involvement.
Patients who underwent cochlear implantation after stapes surgery (10 per cent) also demonstrated a good audiological outcome. CONCLUSION: Stapes surgery is a suitable treatment option for patients with advanced otosclerosis, and should be considered mandatory, before offering cochlear implantation, for those with a demonstrable conductive component to their hearing loss. Se hela listan på en.wikipedia.org Abstract. 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 2019-09-26 · (1) The presence of a refraction of the bone conduction curve with a depth of 10 to 20 dB at a frequency of 2000 Hz (the so-called Carhart notch) in the presurgical tonal audiogram is an unfavorable prognostic factor in relation to closing the cochlear reserve and improving bone conduction after the stapedotomy.
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) .
