What causes Otitic barotrauma?
Key points about ear barotrauma Ear barotrauma is a type of ear damage caused by pressure differences between the middle ear and the outer ear. Scuba diving and air travel are common causes of ear barotrauma. This condition occurs when there is also a problem with your eustachian tubes.
What is otic barotrauma?
Otic barotrauma occurring during air travel involves traumatic inflammation of the middle ear, caused by a pressure difference between the air in the middle ear and the external atmosphere, developing after ascent or more usually descent.
Is decompression sickness a form of barotrauma?
The three major manifestations of barotrauma include (1) sinus or middle ear effects, (2) decompression sickness (DCS), and (3) arterial gas emboli. There have also been minor sequelae to include isolated nerve involvement and facial baroparesis.

What is the most common type of barotrauma associated with snorkelling?
Middle ear barotrauma (MEBT) is the most common being experienced by between 10% and 30% of divers and is due to insufficient equilibration of the middle ear. External ear barotrauma may occur on ascent if high pressure air is trapped in the external auditory canal either by tight fitting diving equipment or ear wax.
How do you treat barotrauma?
Treatment
- Chewing gum, sucking on a lozenge, swallowing, or yawning. Using the mouth helps to open up the eustachian tube.
- Taking an over-the-counter (OTC) nasal decongestant, antihistamine, or both.
- Stopping a diving descent at the first sign of ear discomfort to allow time for equalizing.

When barotrauma leads to an infection or if the pain is intense and symptoms are not resolving or are worsening, you should make an appointment to see your doctor.
How does barotrauma happen?
Barotrauma means injury to your body because of changes in barometric (air) or water pressure. One common type happens to your ear. A change in altitude may cause your ears to hurt. This can happen if you are flying in an airplane, driving in the mountains, or scuba diving.
