The pure-tone audiogram gives the diagnosis of the stage of deafness. Accurate bone conduction (BC) must of course be researched with a contralateral narrow-band masking Fenestral otosclerosis was present in all 12 temporal bones, with 3 temporal bones demonstrating concomitant cochlear otosclerosis. Audiogram results were unavailable or excluded for 5 temporal bones in this group. In clinical practice, cochlear otosclerosis can also be observed. Audiologic rehabilitation of otosclerosis includes fitting of hearing aids and implantable hearing devices. Cochlear otosclerosis usually occurs in long standing case of otosclerotic fixation of the stapes where the disease process invades the otic capsule. This will begin and usually is contained in the basal turn of the cochlea.

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.

Cochlear otosclerosis is a gradually progressive sensorineural hearing loss caused The most common pattern of pure tone audiogram is the “cookie bite” ( see.

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.

There is a moderate tone decay of up to 20 dB. Speech discrimination scores of 80 to 90% are typical of cochlear otosclerosis. 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.
