Ear irrigation is the process of flushing the external ear canal with sterile water or sterile saline. It is used to treat patients who complain of foreign body or cerumen (ear wax) impaction.
Purpose
The purpose of ear irrigation is to remove earwax that is obstructing the ear canal or to remove a foreign object lodged in the ear canal. Ear irrigation is most commonly performed on those who experience a wax buildup that has impaired hearing and irritated the outer ear canal. Ear irrigation is performed in the emergency department as a first-line treatment for a foreign object in the ear canal, because it is less invasive than using an instrument. If the object is a live insect, oil is inserted into the ear to kill the insect; then, the ear canal is irrigated to remove the dead insect. Some foreign objects may be removed from the ear using irrigation alone, but most require a combination of both irrigation and the use of instruments by the physician.
