Otosclerosis is a condition in which there's abnormal bone growth inside the ear. It's a fairly common cause of hearing loss in young adults. There are 3 tiny bones deep inside the ear that vibrate when sound waves enter. They transmit sound waves to the cochlea (inner ear), which converts them into signals that are sent to the brain. In otosclerosis, the stapes (stirrup bone) begins to fuse with the surrounding bone, eventually becoming fixed so it cannot move. This means the sound is no longer transmitted into the inner ear efficiently.
