Earwax is medically called cerumen. If the hardness of cerumen inside the ear hurts when you pull it out, it is considered that cerumen embolism has occurred. Cerumen is secreted by the ceruminous glands in the skin of the external auditory canal. After drying in the air in the external auditory canal, the cerumen is attached to the skin in the form of a sheet, and it will fall out of the body with the action of chewing and swallowing. In some people, cerumen is sticky or the outer ear canal is narrow, resulting in excessive accumulation of cerumen, which forms cerumen embolism. If the cerumen impaction is tightly connected to the skin of the external auditory canal, it may become painful when pulled out. In the case of cerumen impaction, it is not possible to pull out the cerumen. It is recommended to go to the hospital and use sodium bicarbonate solution to soak the cerumen impaction under the doctor’s guidance, and then use the cerumen hook to remove the cerumen under the inner otoscope according to the situation after it is enlarged, or take the method of rinsing to remove the cerumen impaction cleanly. Cerumen impaction should go to the otorhinolaryngology department of the hospital in time and be removed by the doctor.
