It often presents with ear pain, swelling of the ear canal, and occasionally decreased hearing. Several drops of a mixture of alcohol and acetic acid can be put into the ear canal after swimming to insure that it dries adequately.The most serious complications of malignant otitis externa can be avoided by careful attention to early symptoms of ear pain and drainage from the ear canal. The external auditory canal is warm, dark and prone to becoming moist, making it an excellent environment for bacterial and fungal growth.

Inflammation of the external auditory canal, usually due to bacterial or fungal infection; swimming, cerumen accumulation, foreign body, and trauma may all be predisposing factors. It can also occur in other patients who have weakened immune systems. The causative bacteria is usually Diagnosis of uncomplicated otitis externa is usually quite simple.
Diabetes control is also an essential part of treatment.
It can also occur in other patients who have weakened immune systems. It may be impossible (due to pain and swelling) to see much of the ear canal, but this inability itself is diagnostic.If there is any confusion about the types of organisms causing otitis externa, the canal can be gently swabbed to obtain a specimen. This pushes cerumen and normal skin debris back into the ear canal, instead of allowing the ear canal's normal cleaning mechanism to work, which would ordinarily move accumulations of cerumen and debris out of the ear. Typically there is pain with movement of the outer ear. Glands within the skin of the canal produce a waxy substance called cerumen (popularly called earwax). Effective solutions for the ear canal include acidifying and drying agents, used either singly or in combination.Ear drops are the mainstays of treatment for external otitis. Swimmer's ear is an infection in the outer ear canal, which runs from your eardrum to the outside of your head.

It is usually easily treated, although it may tend to recur in certain susceptible individuals. The strategies for preventing acute external otitis are similar to those for treatment. Chronic otitis externa: Chronic inflammation of the skin lining the external ear canal leading to the ear drum. Thus, the warm, moist, dark environment of the ear canal becomes a breeding ground for bacteria.Other conditions predisposing to otitis externa include the use of cotton swabs to clean the ear canals.
