In otosclerosis thee is a characteristic bone conduction curve and this helps the clinician in distinguishing otosclerosis from other causes of conductive hearing losses. The clinician can determine with accuracy the degrees of sensorineural reserve by correcting the bone conduction audiogram for mechanical distortion due to stapes fixation.

The patient's audiogram demonstrated a conductive hearing loss across all frequencies. Hearing loss typically begins in the lower frequencies and advances to

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 is diagnosed by health care providers who specialize in hearing. These include an otolaryngologist (commonly called an ENT, because they are doctors who specialize in diseases of the ears, nose, throat, and neck), an otologist (a doctor who specializes in diseases of the ears), or an audiologist (a health care professional trained to identify, measure, and treat hearing disorders). Otosclerosis is a condition of the bone of the inner ear where the bone of the inner ear grows and stiffens one of the hearing bones.

There is no notch at 2000 Hz. (Adapted from Beales, PH. Otosclerosis . Bristol; John Wright and Sons: 1981. Used with permission.) Carhart’s notch is thought to be typical of otosclerosis (Carhart 1950, 1962). 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.

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.

If you are suffering from hearing loss, come in for an evaluation with our specialists by calling 714-456-7017. 2020-09-17 Otosclerosis is a disorder of bone that affects human beings only and involves the otic capsule (bony labyrinth) and primarily the stapes bone of the middle ear. It is the slow progressive fixation of the stapes bone in the oval window which usually causes the clinical symptoms to become noticed in the form of a conductive hearing loss. Otosclerosis is the abnormal growth of bone of the MIDDLE ear.

A deficiency particularly around 2 kHz (termed a Carhart notch in the audiogram) is characteristic of either otosclerosis or a congenital ossicular anomaly. An audiometric finding characteristic of otosclerosis is an increase in bone conduction threshold with a peak at 2,000 Hz known as Carhart's notch (Carhart, 1950). Although the notch occurs at 2,000 Hz, a reduction in bone conduction sensitivity is seen from 500 to 4,000 Hz which is, on average, 5 dB at 500 Hz, 10 dB at 1000 Hz, 15 dB at 2000 Hz, and 5 dB at 4,000 Hz (Carhart, 1971). Otosclerosis is a condition of the inner ear where one or more foci of irregularly laid spongy bone replace part of normally dense enchondral layer of bony otic capsule in the bony labyrinth. This condition affects one of the ossicles (the stapes ) resulting in hearing loss , tinnitus , vertigo or a combination of symptoms.

Otosclerosis . Bristol; John Wright and Sons: 1981. Used with permission.) Carhart’s notch is thought to be typical of otosclerosis (Carhart 1950, 1962). 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.
