This condition affects one of the ossicles resulting in hearing loss, tinnitus, vertigo or a combination of symptoms. The term otosclerosis is something of a misnomer. Much of the clinical course is characterized by lucent rather than sclerotic bony changes, so the disease is also known as 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 Se hela listan på dizziness-and-balance.com 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.

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 midfrequency hearing range and is characteristically a mixed hearing loss (Hannley 1993). Tinnitus is usually present in a large percentage of patients. 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.

For these women, hearing loss seems to come on more rapidly. In fact, women with otosclerosis in both ears felt they experienced a 33 percent decline in their hearing after a single pregnancy, one study found. 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).

Preoperative audiogram revealed no hearing on the right side and a pure tone average of 13 dB on the left side without  or if a biphasic reflex pattern was noted; (130).

Cochlear, CN VII, CN VIII, or brainstem sites of lesion are represented by vertical, diagonal, inverted L-shape, hori-zontal, and unibox patterns.

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.

Pattern recognition can also help guide inter-pretation of the remainder of the audiogram data. These patterns can extend to the associated immit-tance and speech testing.

Otosclerosis is a condition in which there's abnormal bone growth inside the ear. It's a fairly common cause of hearing loss in young adults. There are 3 tiny bones deep inside the ear that vibrate when sound waves enter.
