Barotrauma is physical
damage to body tissues caused by unequal pressure between an air-filled
space inside the body and the surrounding environment. It occurs when barometric
or water pressure changes rapidly, preventing pressure equalization.
The most common form is ear
barotrauma, affecting the middle ear during airplane takeoff/landing or
scuba diving. Pressure differences stretch or rupture the eardrum,
causing pain, fullness, muffled hearing, tinnitus, dizziness, and sometimes
fluid or blood leakage. Sinus barotrauma produces facial pain and headaches,
while pulmonary barotrauma—rare but serious—can cause lung
overexpansion, pneumothorax, or arterial gas embolism in divers.
Risk factors
include nasal congestion, colds, allergies, and Eustachian tube dysfunction,
which block pressure equalization. Prevention involves yawning, chewing
gum, swallowing, or performing the Valsalva maneuver (gently blowing
while pinching the nose) during pressure changes.
Most mild cases resolve spontaneously
with self-care. Treatment includes decongestants, nasal steroids, pain
relievers, and keeping the ear dry. Severe cases may require antibiotics
for infection, myringotomy (surgical eardrum incision) for fluid drainage,
or ventilation tube placement for recurrent barotrauma.
Understanding pressure dynamics and avoiding altitude changes during illness significantly reduces barotrauma risk for travelers and divers alike.
