List and describe the three most common injuries to the ear
(1) Cauliflower ear is the most common injury to the ear in sports activity; it is caused by extreme friction or by repeated trauma to the ear. (2) Swimmer's ear is an infection of the ear canal; it occurs when moisture is trapped in the external ear canal by an accumulation of ear wax, a foreign object, swelling, or some other blockage. (3) Rupture of the tympanic membrane is most likely to occur in contact sports, water polo, and diving; it can occur as a result of a sudden change in pressure such as that experienced by a diver, or from a fall or slap to an unprotected ear. The membrane can also be ruptured by an object that is inserted too far into the ear. Victims will complain of a loud pop, followed by pain, dizziness, hearing loss, nausea, and vomiting; bleeding and tinnitus may also occur.
