Abstract. Divers who suffer inner ear barotrauma are usually counseled to permanently avoid diving, reasoning that the injured inner ear is at increased risk of further damage.
What is barotrauma diving?
Middle-ear barotrauma (ear squeeze) is the most common dive injury. It occurs when pressure in the air space of the middle ear is not equalized to the ambient pressure. It can cause a ruptured eardrum and can happen either while diving or flying.
How long does it take to recover from barotrauma?
If barotrauma is caused by allergies or respiratory infections, it will often be resolved when the underlying cause has been resolved. Mild to moderate cases take an average of up to two weeks for a full recovery. Severe cases can take six to 12 months for a full recovery after surgery.
What are the signs and symptoms of barotrauma?
The most common symptoms of ear barotrauma may include:
- Feeling of pressure in the ear.
- Ear pain.
- Dizziness.
- Feeling like you have a blocked ear.
- Bleeding from the ears or into the middle ear.
- Ringing in your ears.
- Hearing loss.

Do earplugs help barotrauma?
Pressure-equalizing earplugs cannot be recommended in air travel for preventing ear barotrauma.
What is the cure for barotrauma?
Keep the ear dry. Initial treatment involves oral decongestants and nasal spray to help open the eustachian tube. Antihistamines may also be prescribed if an allergy is a contributing factor. Pain medications are helpful, and eardrops to relieve pain may be used if the eardrum is not ruptured.
What happens during barotrauma?
Barotrauma is physical tissue damage caused by a pressure difference between an unvented space inside the body and surrounding gas or fluid. The damage is due to shear or overstretching of tissues. As a gas-filled space expands or contracts, it can cause damage to the local tissue.

How does barotrauma feel?
Ear barotrauma, or otic barotrauma, is the medical term for that uncomfortable sensation that hits when we’re in an airplane and our ears suddenly feel like they’re stuffed with cotton.
What are examples of barotrauma?
The 3 major manifestations of barotrauma include (1) sinus or middle ear effects, (2) decompression sickness (DCS), and (3) arterial gas emboli.
At what depth does barotrauma occur?
Risk of barotrauma is greatest from the surface to 33 feet (10 meters).
What is the most common barotrauma?
Barotrauma refers to injuries caused by increased air or water pressure, such as during airplane flights or scuba diving. Barotrauma of the ear is common. Generalized barotraumas, also called decompression sickness, affects the entire body.
How do you prevent barotrauma when diving?
Preventing Barotrauma
As the spaces change, the sensitive tissues that make up the ear are distorted, eventually causing them to become damaged. In order to prevent injury, it’s important that the gas spaces inside the ear are kept equalized, i.e., at an equal pressure to the water entering the outer ear.
How do divers fix ear pressure?
VALSALVA MANEUVER | Pinch Your Nose and Blow
This is the method most divers learn: Pinch your nostrils (or close them against your mask skirt) and blow through your nose. The resulting overpressure in your throat usually forces air up your Eustachian tubes.
Who is at risk for barotrauma?
Barotrauma is one of the manifestations of VILI. In a multivariate analysis, the risk of barotrauma was increased in mechanically ventilated patients who had asthma, chronic interstitial lung disease, or ARDS, as well as in those who developed ARDS during mechanical ventilation.
How do you reverse barotrauma?
What Anglers Can Do to Reverse Barotrauma. Anglers can use descending devices or venting tools on fish showing signs of barotrauma. Anglers should assess each fish individually to determine if they need descending assistance and choose a method that they are comfortable using.
Is barotrauma permanent?
Significant barotrauma (BT) may be associated with permanent complications such as hearing and balance deficits; thus prevention and recognition of ETD and BT remain important when evaluating for the hyperbaric environment and treating a pressure-related injury.
