What is Barotrauma?
Barotrauma is damage to tissue damage in the body with a decrease in pressure. Differences may occur depending on the pressure difference affecting many parts of the body. With the sudden changing pressure, tissue damage may occur and permanent dysfunction may occur.
What Are the Types of Barotrauma?
Changes in body structures may recur at different points. The pressure that occurs with the compression of the gas can leave permanent tissue damage in the following organs.
-
Lung Barotrauma (Pulmonary Barotrauma):
Damage to the lungs is usually the result of scuba diving. As the diver approaches the surface, the air pressure held in the lungs decreases and begins to expand. Expanding air can cause ruptures in the lungs, causing pneumothorax. As a result of rupture or perforation in the lungs, shortness of breath, difficulty in breathing and severe pain may occur.
-
Mask Barotrauma:
Another problem seen in divers is mask barotrauma. When diving into water, if the pressure inside the mask is not properly equalized, it will cause extra pressure to be applied to the face and eyes. This condition, which causes bruising, bleeding and varicose-like appearance in the blood vessels on the face, also affects the eyes. The pressure difference causes bleeding and redness in the eyes.
-
Ear Barotrauma:
It occurs when there is a difference between the pressure in the middle ears and the water pressure during entry into the water. It can cause permanent damage to the ear if it progresses by causing swelling and pain in the eardrum. If the pressure increases, the eardrum ruptures and hearing-impairing conditions may occur.
-
Sinus Barotrauma:
The pressure can affect different sinuses, causing pain in the nose and face on ascent to the surface. If the pressure is too high, it can cause nosebleeds.
-
Dental Barotrauma:
It is the pain that occurs in tooth roots or fillings during diving. May damage teeth and enamel.
Causes of Ear Barotrauma
Eustachian tube obstruction is one of the causes of ear barotrauma. The Eustachian tube helps maintain balance during changes in pressure. For example, yawning normally opens the Eustachian tube. When the tube is blocked, symptoms develop because the pressure in the ear is different from the pressure outside the eardrum.
Altitude changes are the most common cause of this condition. One of the places many people experience ear barotrauma is during the ascent or landing of an airplane. This condition is sometimes called airplane ear.
Other conditions that can cause ear barotrauma include:
- Scubadiving
- Walk
- Driving İnto The Mountains
What Are the Symptoms of Barotrauma?
- Earache,
- Tinnitus,
- Hearing loss,
- Dizziness
- The feeling of fullness in the ear is among the symptoms of this ailment.
Diagnosing
Although ear barotrauma may go away on its own, you should consult a doctor if your symptoms are severe pain or bleeding in the ear. A medical examination may be required to rule out an ear infection.
Most of the time this barotrauma can be detected by physical examination. A close look inside the ear with an otoscope can often reveal changes in the eardrum. Due to the pressure change, the eardrum may be pushed slightly outward or inward from where it would normally sit.
Your doctor may also squeeze air into the ear to see if there is any buildup of fluid or blood behind the eardrum. If there are no significant findings on physical examination, the circumstances you usually report surrounding your symptoms will provide clues for an accurate diagnosis.
Barotrauma Treatment Methods
Barotrauma treatment will vary depending on the part of the body that is affected.
-
Lung Barotrauma Treatment:
For the treatment of the damage caused by the pressure, methods such as placing a tube in the chest cavity or applying oxygen therapy may be preferred. By providing re-expansion of the lungs, the deflated lung problem is tried to be eliminated.
-
Sinus and Ear Barotraumas:
Sinus and ear problems can be treated with prescription drugs. Recovery may be slow, but when the course of treatment and use of medication is correct, full cure will be achieved. Tears in the eardrum heal spontaneously, but in cases where it does not show, surgical treatment can be applied.
Ear Barotrauma in Infants
Infants and young children are particularly susceptible to ear barotrauma. This is because the eustachian tubes are smaller and flatter and therefore struggle more with equalization.
If your child shows signs of discomfort, distress, agitation, or pain while experiencing an altitude change, they’re likely experiencing ear barotrauma.
To help prevent ear barotrauma in babies, you can feed them or have them drink during altitude changes. For children with ear conditions, your doctor may prescribe ear drops to relieve pain.
How to Prevent Barotrauma?
Barotraumas occur due to pressure differences. Barotrauma is not expected to occur when the internal and external air pressures are equalized during dives or high altitude flights.
For example, the difference in the face mask can be equalized by blowing air on the face, while the pressure in the ears can be provided by swallowing or yawning.
All these details are transferred to the individuals in the pre-dive trainings. Untrained and unconscious dives can cause serious problems. Pressure problems are frequently seen in pilots and stewardesses as well as in divers.
The sudden drop in pressure inside the aircraft or the high pressure experienced at high altitudes are the sources of the problems. Especially the pressure differences in the ears can progress to rupture of the eardrum and hearing loss.
For this reason, it is important that you stay away from activities that may cause barotrauma unless you have received the necessary training and your health condition does not allow.
Barotrauma: Frequently Asked Questions
What is barotrauma and what causes it?
Barotrauma refers to physical tissue damage caused by a significant difference in pressure between the air (or water) surrounding the body and the air spaces inside the body. It most commonly affects the middle ear and the lungs.
This condition occurs when the pressure in these internal spaces cannot be equalized quickly enough. Common triggers include scuba diving (during ascent or descent), flying in an airplane, or sudden exposure to explosive blasts. In medical settings, it can also be a complication of mechanical ventilation.
What are the symptoms of ear barotrauma?
Ear barotrauma is the most frequent form of this injury. Depending on the severity, symptoms may include:
- Feeling of “Fullness”: A sensation that the ears are clogged or under pressure.
- Ear Pain: Mild to severe discomfort in one or both ears.
- Muffled Hearing: Temporary hearing loss or a sensation of listening under water.
- Dizziness (Vertigo): A feeling that the room is spinning.
- Bleeding: In severe cases, the eardrum may rupture, causing fluid or blood to drain from the ear canal.
What is pulmonary barotrauma and why is it dangerous?
Pulmonary barotrauma is a serious lung injury caused by rapid changes in ambient pressure, most often seen in divers who hold their breath during a rapid ascent. As the diver rises, the air in the lungs expands; if not exhaled, this expansion can rupture the alveoli (air sacs).
This can lead to air escaping into the chest cavity (pneumothorax) or, more dangerously, entering the bloodstream (arterial gas embolism), which can be life-threatening and requires immediate medical attention and often hyperbaric oxygen therapy.
How long does it take for barotrauma to heal?
The recovery timeline for barotrauma depends on the severity and the organ affected:
- Mild Ear Barotrauma: Usually resolves within a few hours to a couple of days with rest and by avoiding pressure changes.
- Eardrum Rupture: May take 2 to 8 weeks to heal on its own.
- Pulmonary/Severe Barotrauma: Recovery can take weeks or months and requires specialized medical monitoring.
If you experience persistent pain, hearing loss, or shortness of breath, consult an ENT specialist or pulmonary doctor immediately.
How can you prevent barotrauma while flying or diving?
Prevention is the most effective way to manage barotrauma. You can protect yourself by following these guidelines:
- Equalize Pressure: Use the Valsalva maneuver (pinching your nose and blowing gently with your mouth closed) during flights or dives.
- Yawning & Swallowing: These actions open the Eustachian tubes to balance pressure in the middle ear.
- Avoid Flying with a Cold: Nasal congestion can block the Eustachian tubes, making equalization nearly impossible.
- Dive Safely: Never hold your breath while ascending and always follow slow ascent protocols.
