Man antar att östrogen ska ha betydelse för utvecklingen av sjukdomen. Det är dock ofarligt att äta p-piller eller östrogentabletter. Ett audiogram är till stor hjälp för att skilja mellan olika typer av hörselnedsättningar som orsakas av t.ex. ledningshinder eller presbyacusis.

Ett audiogram är ett formulär som fylls i under ett hör­ seltest som registrerar hörselnivån vid olika frekvenser på en skala med ljud av olika tonhöjder. Med hjälp av detta kan läkaren/audionomen se vilken nivå och typ av hörselned­ sättning det rör sig om och ge råd om lämpliga behandlingsalternativ. On pure-tone audiometry, there may be a characteristic decrease in bone conduction at 2000 Hz (Carhart notch).

The clinician can determine with accuracy the degrees of sensorineural reserve by correcting the bone conduction audiogram for mechanical distortion due to stapes fixation. Otosclerosis is a common condition affecting the bone of the otic capsule in 7.3% of Caucasian males and 10.3% of Caucasian females. The condition is rare in non-Caucasians, except East Indians, in whom the incidence is approximately the same as pers 1226 AudiologyOnline Article On an audiogram, patients with otosclerosis commonly have conductive hearing loss with a drop in the bone-conduction threshold at 2,000 Hz, called a Carhart notch. This finding, in addition to an absent acoustic reflex, is generally thought to be diagnostic of otosclerosis. Audiograms Audiograms have traditionally been used to diagnose Otosclerosis. It measures air and bone conductions and interactions throughout various frequencies (Hz) at various loudness levels (dB). If an Audiogram results in the hearing threshold greater than 25 dB, then it is abnormal.
