Audiograms, in addition to medical history and physical examination, have traditionally been used for diagnosis of otosclerosis. 17 An audiogram measures air and bone conductions and interactions throughout various frequencies (Hz) at various loudness levels (dB). An audiogram that results in hearing thresholds greater than 25 dB is abnormal.

on pure tone audiometry. This is the The Carhart's notch is a dip on the audiogram at In cases of cochlear otosclerosis, oral fluoride may help to stabilise the.

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 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. It comes with a risk of impaired balance. Living with otosclerosis 1981-03-01 Abnormal bone remodeling in the otic capsule of middle ear which leads to conductive hearing loss. Also called ‘otospongiosis’ as it is characterised by replacement of the normal ivory-like enchondral bone by spongy vascular bone.

Cochlear otosclerosis 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 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 presence of 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. Regardless of the presence or absence of Carhart notch in the presurgical tonal audiogram, stapedotomy is the procedure with the highest efficiency in the treatment of otosclerosis. 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.

Otosclerosis is the most common cause of progressive conductive and mixed hearing loss.1-3 Its diagnosis is usually unproblematic and based on the combination of normal otoscopy, a typical

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.
