Eardrum Perforation
Have you ever woken up during the night and noniced a throbbing pain deeply inside(a)(a) your capitulum? There may eventide be liquid leaking from your stiletto heel, and your perceive could be completely g one(a) from one head. Typically, these are the symptoms of a ruptured eardrum. Of all other things that cause hearing loss, eardrum perforation, or a ruptured eardrum, is the most common reason for hearing loss.
Before substantiateing the causes of eardrum perforation, you must understand roughly basic anatomy and physiology of the eardrum. Even though it is an super thin membrane, the eardrum plays a major role in hearing. Circular in shape, with a diameter barely stretching one centimeter, the eardrum is one of the smallest structures in the ear. It separates the outer ear (ear canal) from the middle ear with miniscule little ear bones. Actually, even thought the eardrum is so small, if you pull another persons ear pinna out and backwards you can see inside the ear canal. After doing this, flashing a light inside the ear canal may help reveal the structure.

If you do get luckily enough to spot the ear drum, it appears as a shiny white film that allows some light to pass through it. Enough with what it looks like though, what does it in truth do for our hearing? The main job of the tympanic membrane is to pass sounds from the environment that we live in to the middle ear. With all(prenominal) sound, no matter how small, the eardrum vibrates. These vibrations are finally picked up by the tiny ear bones mentioned earlier and indeed sent to the inner ear. When children rupture there ear drum, these serial of vibrations do not function well, and hearing loss is the setoff thing one will notice.
