Cerumen has a protective effect on the ear and ear-pulling is generally not recommended, except for mild ear itching or discomfort in the external ear canal caused by water ingress from hair washing or bathing, in which case the external ear canal can be gently swabbed with a sterilized cotton swab as appropriate. Cerumen, the earwax of the external ear canal, has a protective effect on the external ear canal. It contains many antibacterial proteins, which can prevent bacterial infections in the external ear canal. In addition, it is an oily secretion that acts as a hydrophobic agent to avoid moisture in the ear canal. The special odor of cerumen also prevents flying insects from entering the ear. Under normal circumstances, cerumen can be discharged from the external ear canal with chewing, talking and other actions, so it is not necessary to pull out the ear under normal circumstances to avoid the occurrence of diseases after pulling out the ear. If cerumen embolism is formed due to a large amount of cerumen, then one should go to the hospital in time and use tools such as cerumen hooks to remove the cerumen from the ear with the help of a doctor. Patients are advised not to pull out their ears on their own on weekdays, and should consult a doctor in time if they feel unwell.
