Earwax in children can be removed, but it is recommended that it be removed by a doctor rather than blindly at home. Earwax, also known clinically as external ear canal cerumen, is a secretion from the cerumen glands in the ear canal and is present in all people. It maintains a slightly acidic environment in the ear canal and prevents the accidental entry of small foreign objects such as mosquitoes and insects. If the cerumen in the ear canal of children is small, there is no need to pull it out. If the cerumen in the external ear canal is large enough to block the ear canal and cause clinical symptoms such as tinnitus and hearing loss, it needs to be cleared in a timely manner. In this case, it is also recommended to go to the ENT department of the hospital to be operated by a specialist, and parents should not blindly remove it. Firstly, it is easy to damage the soft tissues of the external ear canal and cause bleeding and infection, and secondly, it may push the earwax deeper into the ear canal and aggravate the clinical symptoms, which is clinically called misuse of cotton swabs.
