Barotrauma is a swelling of the eardrum caused by a sudden change in air pressure, most often with temporary obstruction of the Eustachian tube, and usually occurs during air travel. The main symptoms of barotrauma: pain due to swelling of the eardrum, partial loss of hearing, and ringing in the ears. Symptoms usually go away within 3-5 hours and there is no permanent damage. Administration of antipyretic and analgesic can provide good relief from painful symptoms. When flying in an airplane, you should hold candy, swallow, chew gum, or use a nose pinch and puff to open the Eustachian tubes when the plane is descending in order to allow airflow freely into the middle ear and prevent air pressure injuries. Air pressure injuries can also be prevented in infants if bottle-feeding or breastfeeding during the ascent and descent of the airplane. It is generally recommended that children and adults with colds, upper respiratory tract infections, chilblain fever, and ear infections should avoid air travel to avoid damage from barometric pressure injuries.
