During the summer vacation, many parents choose to take their children swimming to cool down, but some children may experience ear pain during or after swimming. Children's physiological structure and immune system are not yet fully mature, and they are prone to ear problems after swimming, "said Liu Zhijian, director of the ENT department at Shenyang Children's Hospital in Liaoning Province. Liu Zhijian introduced that children who experience ear pain after swimming, some of whom suffer from otitis media and otitis media, and some have even developed boils and swelling in the external auditory canal. The middle ear cavity and nasal cavity of the human body are connected through the Eustachian tube, which is relatively flat during childhood. When children swim and choke on water, bacteria and viruses in the water are prone to retrograde infection of the middle ear cavity, leading to otitis media. Improper treatment of ear water intake during swimming may cause infection of the skin follicles in the external auditory canal, causing otitis media. If otitis media is not treated in a timely manner, it may form an external auditory canal furuncle, manifested as local swelling and narrowing of the ear canal. Liu Zhijian said that ear pain caused by different causes needs to be treated differently: after seeking medical examination and evaluating the degree of infection, patients with otitis media can apply ear drops externally, and if necessary, use mucus excretors or antibiotics for treatment; Patients with external otitis or boils should undergo local physical therapy and medication under the guidance of a doctor. During treatment, they should avoid eating beef, mutton, spicy food, seafood, etc. How should children cope with ear pain when swimming? If the ear feels stuffy and swollen due to water ingress, parents can ask the child to keep their head tilted and the affected ear facing down, gently shake their head or jump to let the water flow out; use ear cleaning tools such as cotton swabs or ear spoons to gently clean the ear canal, avoiding excessive force to damage the ear canal. If the pain persists, seek medical attention promptly, "said Liu Zhijian. In addition, Liu Zhijian suggests that children should use correct swimming posture and techniques when swimming, avoid sudden diving or rapid diving into the water, and reduce the risk of eardrum damage; Pay attention to cleaning your ears before and after swimming, and use a cotton swab to absorb the water in your ear canal in a timely manner after swimming to avoid water retention and infection; At the same time, choose a swimming pool with good water quality to reduce the risk of bacterial infection.
