Re: If an eardrum becomes punctured, what may happen if water leaks in?

John-  Good question, and the major problem that can occur with a punctured 
ear drum in a swimmer not using earplugs is infection.  This can occur with 
the water exposure, but also with the diving or changes in pressure when we 
turn in the water etc...that may "jet" the water into the ear.  People can 
also have problems with hearing later on whether from the infection, scar 
tissue, or if the perforation doesn't heal.  So be kind to your ears and if 
you do have a perforated ear drum, protect it!
