A yellow or brown secretion, also called cerumen, produced by glands in the outer ear canal. Some people produce so much wax that it regularly obstructs the canal. Excess earwax may produce a sensation of fullness in the ear and partial deafness. Prolonged blockage may irritate the canal. Wax that causes blockage or irritation may come out after being softened with oil. Otherwise, it should be removed by a doctor. This is usually done, after wax is softened, by syringing of the ears.
