Ear trauma

چکیده
Although gradual changes in air pressure may result in rupture of the tympanic membrane, this most often occurs from a rapid change. Sudden forceful blows on the ear, which seal the external auditory meatus, can result in sufficient increase in the air pressure in the ear canal to rupture the tympanic membrane. The most frequent single cause is a blow on the ear, usually with the open hand. This may occur in sporting and not so sporting situations. A blow on the ear from a ball or a fall on water are not uncommon causes of trauma to the tympanic membrane.
