Fungi result from improper function of the immune or through a hole in the eardrum. Otitis media associated with sterile is considered serious, and it is characterized by the presence of clear fluid at the back of the eardrum as a result of an allergy, radiations, exposure to smoke or other sources. A person, infected experiences periods of discharge, although not painful and the tympanic membrane may bulge or fail to move.   It results in loss of hearing. The disease may affect anybody although it is common in children below five years.


Otitis Externa

Otitis Externa is an inflammation of the external ear canal, the auricle. It is caused by insertion of objects in the ear like a small stone or seeds in children. Adults are also affected when they insert sharp objects in the ear which creates a hole in the eardrum. When the wax is pushed deep into the ear, it can also result in the disease. Other causes include using earplugs, exposure to water while swimming and skin related problems. A person infected experiences small discharge from the ear, itching and the ear canal narrows continuously.
