Otosclerosis is a condition characterized by abnormal bone growth inside the ear leading to hearing loss.Normally, when sound waves enter the ear, the three tiny bones deep inside the ear vibrate thereby sending sound waves to the cochlea or the inner ear.In Otosclerosis , the stapes or the stirrup bone fuses with the surrounding bone thus becoming fixed. Thus sound is no longer transmitted into the inner ear efficiently leading to hearing loss.
HOW IS OTOSCLEROSIS DIAGNOSED?
Diagnosis is done by an ENT based on above symptoms along with doing an X-ray to check the bone growth in the ear and how big it is.
HOW IS OTOSCLEROSIS TREATED?
Treatment for this process is three-fold starting with medicines that help in fixing or stopping this bone growth. Post this, surgery is done to repair the damage, which also includes stapedectomy and involves a small drilling in the ear. And lastly, Amplification is done for boosting the hearing process.
DID YOU KNOW?
This is an inherited disease. The primary form of hearing loss in otosclerosis is conductive hearing loss (CHL) whereby sounds reach the eardrum but are incompletely transferred via the ossicular chain in the middle ear, and thus partly fail to reach the inner ear (cochlea).
