Ear irrigation is used to treat earwax impaction or foreign objects in the ear canal. It involves flushing the ear canal with sterile water or saline to remove debris. Contraindications include a perforated eardrum, ear infection, or foreign objects that may swell with moisture. The procedure positions the patient and inserts a bulb syringe filled with warm sterile solution into the ear canal while visualizing for debris removal. Complications can include ear infection, vertigo, or temporary or permanent hearing loss if not performed carefully.
