Otosclerosis is the growth of abnormal new bone in the inner ear bones needed for hearing. This growth prevents proper functioning of ear structures. Hearing loss can occur when the new bone changes the shape of the stapes and other ear small bones reducing their movement. This is a common cause of hearing loss.
Hearing aids may be effective for conductive and sensorineural hearing loss.
In many cases, a procedure called a stapedectomy may improve hearing. This operation is usually done with replacement of the diseased bone with an artificial device that can transmit sound waves to the inner ear. Stapedectomy is effective and frequently returns hearing to a near normal level.
Other surgical treatment may include stapedectomy, circumferential stapes mobilization surgery, or cochlear implantation.
Fluoride tablets are sometimes prescribed to stabilize the condition and prevent further sensorineural hearing loss. However, this treatment remains controversial and unproven.
