Earwax blockage depends on the amount of earwax and the specific situation. Earwax, also called cerumen, is cerumen that is normally secreted by the cerumen glands in the outer ear canal. A small amount of cerumen in the form of crumbs or flakes can be directly clamped out with tweezers under an otoscope or endoscope or sucked out with a negative pressure suction device. If the cerumen is large and soft, it can also be removed with tweezers under the otoscope or endoscope. If the cerumen is a large, hard mass that blocks the external ear canal and causes significant pain with forceps and does not move, the large cerumen should be soaked in sodium bicarbonate repeatedly for 15 minutes at a time, and after 15 minutes, the external ear canal should be dried, and then soaked in sodium bicarbonate for one hour. The outer ear canal can be cleaned.
