Why do children get ear infections?

Young children are prone to ear infections (called “otitis media”) because of their developing head and neck structures. One of these developing structures is the eustachian tube, a small connection between the back of the ear and the back of the nose. This structure allows for the regulation of air pressure, ventilation, and drainage from the middle ear space into the back of the nose. Unfortunately, the eustachian tube is not very well developed in some children. Reflux (or back-up) of infected fluid from the nose into the ear may occur. Likewise, the eustachian tube sometimes does not drain well and allows material to build up in the ear.

How to clean the ear?

Ear can be cleaned by itself because of migratory capacity of skin of ear canal. If you scratch ear often you will get more wax and sometimes you may injured the eardrum.
