![]() This is similar to a car tire, which has to have the perfect amount of pressure in it for a smooth ride. In both parts of the inner ear, your sense organs depend on a perfect balance of pressure to translate the information they are getting from the outside world into nerve signals. If one organ is giving information that doesn’t match the other side, you may feel dizzy. The brain compares information from both of these organs to figure out your direction and speed. At the same time, on the opposite side, the hairs are pushed in the “off” direction, which decreases its electrical activity. As you move in one direction, the fluid pushes the hairs in that ear in the “on” direction, which increases its electrical signals to the balance nerve. In the balance system, movements of your body and head create waves of pressure changes inside the vestibular organs. Movement Creates Different Pressure Waves in Each Ear The “traffic,” or sound pressure, needs to flow freely through the hearing organ to stimulate the hearing nerve. ![]() If there is a concrete barrier on the far end of the intersection, traffic will build up, and eventually it will back up to the traffic light. ![]() For traffic to flow through the traffic light, the intersection needs to be clear. Think about these pressure changes like the flow of traffic along a busy road through an intersection. The round window acts as a vent that allows pressure out. After the pressure waves travel through the hearing organ, they exit through a second flexible cover at the other end, the round window. This creates pressure changes at the oval window, a flexible cover over the opening of the fluid-filled hearing organ. In the hearing system, sound (which is simply changes in pressure in the air) enters the ear through the ear canal, which vibrates the eardrum and bones of the inner ear. When pressure moves the fluid inside these structures, the fluid moves the hairs, which creates electrical signals that the hearing and balance nerves then send to the brain for interpretation. Although the organs look different and have different functions, the way they work is quite similar.īoth the hearing and vestibular organs are fluid-filled tubes, containing small hairs that are sensitive to changes in pressure. The inner ear contains two main structures: the cochlea (the hearing organ) and the semicircular canals and otoliths (the vestibular and balance organs). What Causes Third Window Syndrome? The Inner Ear is a Pressure Detection System ![]() Read on to find out more about the symptoms, causes and treatments for this disorder. Fortunately, this group of disorders is often medically or surgically treatable. These abnormalities can lead to vestibular symptoms such as dizziness, imbalance and difficulty focusing the eyes, as well as hearing symptoms such as hearing loss and sensitivity to loud sounds. The most commonly recognized is superior semicircular canal dehiscence (SSCD), but there are other types. Third window syndrome describes a group of inner ear disorders that results from a leakage of pressure and/or fluid from the inner ear structures.
