Wax is normally secreted by glands which lie in the ear canal. When first secreted it is soft and colourless, but with exposure to air becomes hardened and acquires a brown colour. Its function is to act as a filter for the ear, trapping particles of dust and dirt when they enter the ear canal. Usually the actions of chewing and the constant renewal of the ear canal’s lining ensures that wax is moved outward. Sometimes a build up of wax can block the ear canal, and may cause discomfort or interfere with hearing. Earwax can be softened by placing 2 drops of paraffin oil in the ear for 3 consecutive nights. Never use a cotton bud to remove wax inside the ear canal, as this can easily cause damage by pushing the wax deeper inside the ear. Some children may have to use ear drops on a regular basis to prevent a build up of wax. The doctor may sometimes have to use a special syringe to flush out wax that is blocking the ear.
