Barotrauma
Condition
(Ear Barotrauma, Barotitis Media, Ear Popping, Ear Pressure, Airplane Ear; Sinus Barotrauma, Aerosinusitis, Barosinusitis; Pulmonary Barotrauma, Pulmonary Overpressurization Syndrome)
Definition
Barotrauma is pain or tissue damage due to a change in pressure. It happens when pressure outside the body is different from pressure inside the body. This leads the air inside the body to shrink or swell.
Pressure changes may affect the:
- Middle ears (most common)
- Sinuses
- Lungs (most serious)

Causes
Barotrauma is caused by:
- Sudden or severe changes in pressure
- Blockages in the ears, sinuses, or lungs
Risk Factors
Things that raise the risk of this problem are:
- Airplane travel
- Scuba diving
- Mechanical ventilation
- Exposure to shock waves from an explosion
Blockages in the inner ear can raise the risk of barotrauma. They may be caused by:
- Allergies or colds
- Middle ear infections
- Problems in the eustachian tube—a small tube that connects the middle ear to the throat
- Cleft palate or lip
Things that raise the risk of sinus barotrauma are:
- Sinus infections, colds, or allergies
- Defects in the sinuses
Lung problems or damage may raise the risk for barotrauma in the lungs.
Other things that may raise the risk are:
Symptoms
Symptoms of barotrauma depend on the areas affected.
In the ears, it may cause:
- Discomfort or pain in one or both ears
- A clogged or pressured feeling in the ears
- Lightheadedness
- Ringing in the ear— tinnitus
- Temporary hearing loss
- Rarely, bleeding from the ear
In the sinuses, it may cause:
- Sinus pressure and/or pain
- A feeling of fullness in the head
- Nosebleeds
- Headaches or tooth pain
In the lungs, it may cause:
Diagnosis
The doctor will ask about symptoms and past health. A physical exam will be done. The doctor will look in the ears for irritation or damage.
If the lungs could be affected, tests may be:
- Chest x-ray
- CT scan
- MRI scan
- Lung perfusion scan
- Pulmonary function tests—to measure lung function
- Pulse oximetry—to measure oxygen in the blood
Treatment
Treatment depends on the area affected. Barotrauma in the lungs is serious. It needs care right away.
Treatment options for barotrauma may be:
- Easing pressure in the ear by:
- Chewing gum
- Yawning
- Gently breathing through the nose while pinching the nostrils
- Medicines to ease a stuffy nose and sinuses, such as:
- Decongestant nasal sprays
- Oral decongestants
- Oral antihistamines
- Pain medicines
- Antibiotics—to treat infections from bacteria
- Surgery to ease pressure in the ears—if other methods do not work
Lung barotrauma is treated right away with oxygen. It is given through a face mask or a tube under the nose.
Prevention
To reduce the risk of this problem:
- When flying:
- Ease pressure—with ear plugs, chewing gum, yawning, or mouth breathing
- With a cold or sinus problems—cancel the flight or take a decongestant
- Before diving:
- Get trained and certified
- Follow safety guidelines
