In otosclerosis, calcification occurs at the junction of the stirrup with the inner ear, and the stirrup loses its mobility. Depending on the degree of calcification, the patient experiences a hearing loss because the sounds coming from the outside cannot be transmitted to the inner ear. In addition to hearing loss, complaints of tinnitus, dizziness and imbalance can also be seen.


Although the exact cause is not known, it has been shown to be genetically transmitted. It has been reported that some virus infections and hormonal factors cause this disease, and this disease progresses rapidly in pregnant women. It is seen approximately two times more in women than in men. The disease occurs, on average, between the ages of 15-45. Onset before age ten and after age 45 is rare.



Diagnosis is made by ear examination and some hearing tests. Calcification focus can be shown on computed tomography. The fact that the stirrup is not mobile during the operation confirms the diagnosis.


Surgically, the stirrup is removed and a prosthesis is placed in its place. Hearing aids can be used in patients who do not want to have surgery or whose hearing loss is not suitable for surgery.
