Middle ear barotrauma (MEBT), also known to underwater divers as ear squeeze and reverse ear squeeze, is an injury caused by a difference in pressure between the external ear canal and the middle ear. It is common in underwater divers and usually occurs when the diver does not equalise sufficiently during descent or, less commonly, on ascent.
Sinus barotrauma or aerosinusitis has been known since the early development of aviation medicine. However, it was during World War II that the subject first received serious attention and the pathogenesis of the disease was understood to be due to exposure to high altitude flights. Rapid altitude changes with accompanying changes in ambient ...
Nevertheless, barotrauma occurs and can be life-threatening, and procedures for first aid and further treatment are an important part of diving medicine. Barodontalgia.

Inner ear decompression sickness (IEDCS) can be confused with inner ear barotrauma (IEBt), alternobaric vertigo, caloric vertigo and reverse squeeze. A history of difficulty in equalising the ears during the dive makes ear barotrauma more likely, but does not always eliminate the possibility of inner ear DCS, which is usually associated with ...
Barotrauma is physical damage to body tissues caused by a difference in pressure between a gas space inside, or in contact with, the body and the surrounding gas or liquid. [1] [2] The initial damage is usually due to over-stretching the tissues in tension or shear, either directly by an expansion of the gas in the closed space or by pressure difference hydrostatically transmitted through the ...

IEDCS and inner ear barotrauma (IEBt) are the inner ear injuries associated with ambient pressure diving, both of which manifest as cochleovestibular symptoms. The similarity of symptoms makes differential diagnosis difficult, which can delay appropriate treatment or lead to inappropriate treatment.
