During ascent internal over-pressure is normally passively released through the eustachian tube, but if this does not happen the volume expansion of middle ear gas will cause outward bulging, stretching and eventual rupture of the eardrum known to divers as reverse ear squeeze. This damage causes local pain and hearing loss.
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 ...
The eardrum is stretched due to a pressure difference between the outer and middle ear spaces. If the eardrum stretches sufficiently, it may rupture, which is more painful. Water entering the middle ear may cause vertigo when the inner ear is cooled. Contaminants in the water may cause infection. [31]
