Treatment consists of analgesia and topical steroid ear drops. People of all ages can have ear barotrauma. This might cause bleeding or other damage to the outer, middle, or inner ear. The eardrum separates the outer and middle ear. When that happens, the difference in pressure can damage the eardrum. Sometimes the eustachian tube can’t open normally when there are changes in pressure. This equalizes the pressure between the middle ear and the outside. Ear injuries can lead to dizziness, balance problems, hearing loss or changes in the ear’s appearance. Accidents, loud noises, changes in air pressure, trauma from contact sports and foreign objects in the ear can cause injuries. If the external pressure is greater or less than the middle ear pressure, the eustachian tube should open. Ear injuries and trauma can cause damage to any part of the outer or inner ear. This tube stays closed most of the time.įor your hearing to work normally, the pressure inside the middle ear has to match the air pressure in your environment. It also contains the opening of the eustachian tube, which connects to an area behind the nose. Inner-ear barotrauma results from difficulty equalizing middle-ear pressure, but unlike middle-ear barotrauma, is relatively rare. It contains 3 small bones that help transmit sound. The middle ear is an air-filled space between the inner and outer parts of the ear. It can cause pain and sometimes lifelong (permanent) hearing loss. It is caused by pressure differences between the inside of the ear and the outside of the ear.
