Since these infections are usually confined to the skin of the ear canal the chances of permanent hearing loss or other damage to the ear is very small.
If left untreated the infection can spread into the bone of the ear canal, eardrum, middle ear and mastoid, resulting in permanent damage. This is very rare.
The mainstay of treatment is cleansing of the car canal. Since the canal extends over 1 inch into the head this usually is done by an ear specialist. In the typical case this takes 1-4 visits. In chronic cases, cleansing may be required every 3-4 months indefinitely.
When the ear canal is acutely infected antibiotic eardrops, such as Cortisporinâ Otic Suspension, are prescribed because they penetrate deep into the tissues. With the infected ear turned up put 3 or 4 drops into the ear canal, wiggle the ear to help the drops penetrate deeply, and put a small piece of cotton in the outer part of the ear until the excess medicine drains out.
In severe ear canal infections oral antibiotics (such as Penicillin, or Ampicillin) and pain killers (such as Tylenol with codeine, or Vicodin) are prescribed. These medicines should be taken sparingly and only when needed.
Cultures of the infection are not taken because of the high cost ($40-80), unless the infection is very persistent.
Avoid getting the ear wet while the infection is occurring. Do not swim. Bathe or shower with a piece of cotton in the outer car and avoid splashing water in the ear.
Avoid any chemical materials such as perfumes, colognes, scented shampoos or hairsprays. They can irritate the inflamed skin.
Report any long-term skin ailments, such as psoriasis or seborrhea.
In recurring cases, an antibiotic powder and atomizer will be prescribed. A very light puff of the powder is all that is required every other day. The frequency of powdering is adjusted according to the severity of the problem.
In recurring cases an operation to widen the ear canal may be required. This can be done under local anesthesia in the office or an "in and out" surgery facility.
