	Ear Canal Infection
		Ear canal infection (otitis externa or swimmer's ear) is an infection of the outer ear canal skin and can occur in acute and chronic forms.
		Ear canal infection (otitis externa) is an inflammation or infection of the outer ear canal, the passage leading from the external ear to the eardrum.
		Unlike a middle ear infection (otitis media), the pain of an ear canal inflammation or infection is worse when you chew, when you press on the "tag" in front of the ear, or when you wiggle your earlobe.

		This part of the ear is a cartilaginous structure covered with skin of adequate thickness to provide perspiration and sebaceous gland and the growth of hair, a secondary trait in aging males.
		The overall structure of the adult ear canal is a roughly S-shaped elliptical cylinder, with a length of ~30 mm.
		The compression and expansion action of the moving condyle on the ear canal, and the resulting change in shape and volume, is the major factor in acoustic feedback with earmolds.

	Ear canal - Wikipedia, the free encyclopedia
		The ear canal, or external auditory meatus, is a tube running from the outer ear to the middle ear.
		The ear canal extends from the pinna to the eardrum and is about 26 mm in length and 7 mm in diameter.
		The net effect of the head, pinna, and ear canal is that sounds in the 2,000 to 4,000 Hz region are amplified by between 10 and 15 dB.

	Ear Structure
		The external ear consists of the outer portion of the ear that is visible on the side of the head, called the pinna, and the ear canal that leads to the tympanic membrane, also known as the ear drum.
		Its outer border is the thin membrane known as the ear drum, or tympanic membrane.
		As sound strikes the ear drum, it vibrates and in turn transmits these vibrations to the three small bones of the middle ear: the malleus, the incus, and the stapes.

		Chronic infections that thicken and occlude the ear canal and tumors that fill the middle ear or external ear canal are the most common problems requiring surgery on the ear.
		Since the ear cannot be kept dry, and because an infection thickens the tissues of the ear canal, proliferative debris is trapped in the ear.
		This procedure is used for diseases of the external ear and involves removing and reconstructing a small lateral portion of the ear canal.

	Completely-In-the-Canal Hearing Aids
		Canal aids are quite a bit larger than CIC aids and sometimes have problems with working their way out of the ear.
		Canal aids are the style you frequently see in mail order hearing aids, since they just are pushed into the ear canal opening.
		Since the outer portion of the typical CIC aid is well down in the ear canal, it is much less visible, and it is practically immune to the wind noises that bother conventional aid wearers.

	Ear Wax and Ear Care by MedicineNet.com
		Ear wax is helpful in normal amounts and serves to coat the skin of the ear canal where it acts as a temporary water repellent.
		Glandular secretions, sloughed skin cells, normal bacteria present on the surface of the canal, and water may all be present in ear wax.
		Most of the time the ear canals are self-cleaning; that is, there is a slow and orderly migration of the skin lining the ear canal from the eardrum to the outer opening of the ear.

	Swimmer's Ear (Otitis Externa)
		Otitis externa - commonly known as swimmer's ear - is an infection of the ear canal, the tubular opening that carries sounds from the outside of the body to the eardrum.
		Dry skin or eczema, scratching the ear canal, vigorous ear cleaning with cotton-tipped applicators, or inserting foreign objects like bobby pins or paper clips into the ear can all increase the risk of developing otitis externa.
		Sometimes, in a child with a middle ear infection, pus collected in the middle ear can drain into the ear canal through a hole in the eardrum and cause otitis externa to develop.

		The external ear canals in the dog and cat are shaped in the form of a capital letter L. Due to this cornucopia like or funnel shape canal, any sound made will be collected and amplified to some extent before it reaches the ear drum.
		As the long portion of the L shaped ear canal points up in both the dog and cat, any fluid or debris produced will likely remain in the canal and result in an excellent environment for opportunists, such as bacteria, to grow.
		The normal ear canal is clean in appearance at all times unless there is something wrong.

		A known effective home remedy for "swimmer's ear" (the fungal infection kind) and if there is no perforation of the ear drum, is to obtain some powdered boric acid and a pint of ethyl alcohol (not methyl alcohol which is the more common kind) from your local pharmacy.
		If the middle ear infection is cured, the ruptured ear drum usually heals on its own, although sometimes surgery (tympanoplasty) is indicated if the rupture is extremely large.
		The buildup of fluid in the middle ear reduces the movement of the eardrum and ossicles, and hearing is reduced.

	UT Hearing Aids - Completely-in-the-Canal hearing aid
		Others have ear canals, which are too small to accommodate even the CIC hearing aid style and some hearing aid users can not tolerate long ear canal molds because of discomfort.
		Thus ear canal anatomy and individual manual skills play a part in determination of candidacy for the CIC hearing aid.
		Because the CIC fits deep into the canal, the output is closer to the eardrum and thus the amount of amplification available is greater for the same amount of power as in other hearing aids.
