External otitis is a medical condition, in which ear canal infection occurs. External otitis can affect the whole canal, or just 1 small area, as a furuncle (boil). External otitis, known as a swimmer’s ear, is most likely to occur during the swimming season. A different bacteria, or rarely, fungi; may result in generalized external otitis; such bacteria as staphylococcus, commonly results in boils (furuncle). Some individuals, such as with scalp dermatitis, eczema, psoriasis, or allergies, are especially likely to have external otitis. Damaging the ear canal at the time of cleaning it or getting water or irritatnts including hair dye or hair spray in the ear canal causing external otitis. The ear canal clears itself by moving dead skin cells from the ear drum out through this canal as if it was on a conveyor belt. Trying to clean the canal with a cotton swab is interrupting such self-cleaning mechanism and may push debri toward the person’s eardrum, where it accumulates. Earwax and collected debris tend to trap water, that gets into the canal of the ear, while swimming or during a shower. The resulting softened, wet ear canal’s skin is more likely to be infected by fungi or bacteria. External otitis symptoms include malodorous discharge, pain, and itching. If the ear canal fills with debris and pus or swells, hearing becomes impaired. Commonly, the canal hurts and tends if the pinna (external ear) is pulled or if the pressure is put on the skin fold in the ear canal front. When a physician looks into the ear canal by using device otoscope, the canal skin appears swollen, red, and litters with debris and pus. Furuncles (boils) result in severe pain. When furuncles rupture, pus and small blood amount can leak from the ear. Treatment of generalized external otitis consists of removal of the infected debris from the ear canal with dry cotton wipes or suction. Then, hearing is often ruptured to normal. An individual is given ear drops, consisting of antibiotics to instill in the ear few times a day for about 1 week period. Certain ear drops also consist of corticosteroid to decrease swelling. In some cases, ear drops consist of diluted acetic acid used to help restore ear’s normal aciditiy. Analgesics including codein and acetaminophen can subside the pain for the first one to two days, unless the inflammation starts to decrease. In external otitis, boils are allowed on their own.
