Ear discharge is a general term that refers to any fluid and substance that comes out of the ear. It is referred to medically as otorrhea. Types of ear drainage include blood, pus, fluid, and earwax, which is the most common.
While earwax coming from the ear is not a cause for concern, ear drainage can sometimes be caused by an irritation or infection. A ruptured eardrum can cause a white, slightly bloody, or yellow discharge from the ear. Dry crusty material on a child’s pillow may indicate a ruptured eardrum, which needs immediate medical attention. Causes of ear drainage include a ruptured eardrum, head injury, ear infection, foreign object, cholesteatoma, or mastoiditis.
