Two-year-old babies with hardened earwax, if the blockage of the ear canal affects hearing, should go to the hospital to perfect otoscopy to clarify the cause and have the doctor remove the hardened earwax. Earwax is a flaky yellow secretion from ceruminous glands in the ear canal, often attached to the wall of the external ear canal, and its medical name is cerumen. Under normal circumstances, cerumen can self-complete the process of discharging from the body through human chewing, opening the mouth and other jaw movements, which is not harmful to the human body. However, if a 2-year-old baby produces too much cerumen for a short period of time, the cerumen may become hard and cannot be discharged for a long period of time, resulting in cerumen embolism, which may have an effect on hearing. In this case, cerumen can be removed through otoscope and ear canal flushing under doctor’s guidance. If a 2-year-old baby has a hard lump of earwax, it is recommended to go to the hospital to clarify the cause of the hard lump of earwax and then treat it. It is not recommended for parents to help their children to pull out the hard lump of earwax to avoid accidents and damages to the external ear canal.
