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. 2020-06-01 · However, only a small number of Japanese patients with otosclerosis are considered to be severe cases, which indicates that a large number of cases show a stiffness tilt type of audiogram in Japan. As for the Carhart notch at the 2-kHz bone conduction threshold dip, there are some reports of patients with other ossicular chain anomalies also showing the same finding [5 , 6] .

Pure tone audiometry assesses hearing thresholds for air and bone conduction over a range of pure tone frequencies. The results of the assessment are used to Pure tone audiometry. Pure tone Air conduction. Pure tone Bone High frequency audiogram.

19 Apr 2012 Pure tone audiogram, Otosclerosis, Otology, Otolaryngology This is a dip at 2000 Hz in the bone conduction audiograms of these patients. Etiology is then confirmed by an audiogram and/or CT scan. Otosclerosis affects more than three million Americans, or about 10 percent of the population.

Otosclerosis is a condition of the ear caused when an abnormal growth surrounds the tiny vibrating bones of the middle ear, resulting in conductive hearing loss.

Carharts notch 2 is actually a decrease in bone conduction of 10-15 dB seen around 2 kHz frequency. Bone conduction actually means sensorineural reserve. After successful stapes surgery the carharts notch disappears when the conductive hearing improves.
