This condition is called otitis media. Sometimes infections occur in the outer ear, but not usually among children. It is usually caused by an irritation of the skin in the ear canal. Inner ear infections are much less common. They can be symptoms of more serious diseases and are more likely to cause deafness.
Ear infections are very uncommon in adults.
