Hole in ear drum
The ear drum or tympanic membrane is a very thin membrane that separates the outer and middle ears. Holes or perforations in the ear drum can be caused by trauma or infection. If the perforation is recent, timely treatment can increase the chance that the ear drum will heal by itself. Long standing holes or perforations in the ear drum are unlikely to heal and can cause hearing loss and increased risk of infection.
Once there is a hole in the ear drum, the ear must be kept dry as water entering the ear can easily cause middle ear infection. If infections are frequent, then surgical repair of the hole may be necessary.
