Otosclerosis
Otosclerosis is a disease of the inner ear that causes the stapes bone in the middle ear to thicken and stiffen, resulting in the inability to move as freely as it should. This can cause a person to feel dizzy when they turn their head or move around. The actual cause of otosclerosis is unknown, but it is most common in people between the ages of 20 and 40.
Inner ear disorders like otosclerosis can cause vertigo by affecting the semicircular canal system. This system comprises three fluid-filled tubes connected to one another and stays horizontal regardless of your head’s position. These tubes connect with tiny hair cells within your inner ear, which send signals to your brain that tell you what position your head is in so you don’t get dizzy. Otosclerosis makes your head more likely to become out of balance because your stapes bone doesn’t move as much as it should when it’s supposed to hit against the side wall of the oval window. As a result, vertigo symptoms can occur when you turn your head or move around.
