Overview and Facts about Otosclerosis
Otosclerosis is a condition that results in hearing loss. It is caused by an abnormal growth of bone in the middle ear.
The abnormal bone growth prevents the stapes (one of the three small hearing bones underneath the eardrum) from vibrating normally in response to sound. Usually, the problem can be resolved with surgery.
Signs and Symptoms of Otosclerosis
Typically, people with otosclerosis experience hearing loss in one ear, which then moves to the other. The hearing loss may come on very gradually. The first thing that many people notice is an inability to hear low-pitched sounds.
Other signs and symptoms associated with otosclerosis include:
- Muffled or plugged ear sensation
- Ringing or humming or static-like noise in the ears (also known as tinnitus)
Causes and Risk Factors of Otosclerosis
Otosclerosis is thought to be a hereditary disorder. However, in some instances, it can be associated with measles during pregnancy.
Some medical experts believe that it may also be linked to immune disorders or stress fractures in the bony tissue in the inner ear.
If the condition is left untreated, it will worsen, and progressive hearing loss may occur over many years.
Tests and Diagnosis of Otosclerosis
Your doctor will first take your medical history and perform an examination of your ears. If your doctor thinks that you may be suffering from otosclerosis, they will refer you to an otolaryngology specialist, a medical professional who specializes in ear, nose, and throat issues.
The otolaryngologist will examine your ears and test your hearing. In some cases, the specialist will order a CT scan to get a more detailed image of your condition.
Treatment and Care for Otosclerosis
People who are suffering from otosclerosis can use hearing aids to help them hear, but this will not cure the hearing bone problem. As the condition progresses, more powerful hearing aids will be needed.
Surgery for otosclerosis is a common and relatively simple procedure that involves removal of a portion of the abnormal hearing bone and replacement with a tiny replacement implant. This surgery has a very high chance of improving hearing and tinnitus.
