Quick Summary:

• Otosclerosis is a very common ear condition. The term Otosclerosis is derived from Greek words ‘oto’ for ear and  ‘sclero’ for hard
• Otosclerosis is the abnormal growth of bone causing sclerosis (hardening of tissue) in the middle ear. As the bone grows, it affects other parts of the ear, interfering with the transmission of sounds, which results in a hearing loss
• Sclerosis occurs in the temporal bone (located at the side and base) of the skull. Multiple areas of sclerosis can be seen on a temporal bone
• There are three bones in the middle ear, called malleus, incus, and stapes. These bones are connected to each other and help in the transmission of sound waves. When the footplate of the stapes bone becomes fixed to the cochlea (auditory portion that has the hearing nerve) due to sclerosis, it results in conductive type of hearing loss
• Otosclerosis commonly affects young and middle-aged adults. There are no clear causes why the condition occurs, but there are evidences linked to viral infections and hormonal changes
• The signs and symptoms of Otosclerosis may include hearing loss and paracusis (ability to hear well against a noisy background)
• The treatment of the ear condition depends upon the severity of hearing loss and may include the use of hearing aids and surgery for severe hearing loss
• Otosclerosis can result in a complete deafness, if the condition remains untreated. Some hearing abilities can be improved with surgery , though it cannot completely cure the condition
