Every summer, I always see children in my clinic with anxious guardians asking for information about ear problems. How many days does it take to heal? We just enrolled in swimming lessons and they stopped? In fact, if parents are careful and add some medical knowledge, such ear diseases can be prevented. If you do the following points, you can enjoy summer swimming with your children without worry! 1, you should know that the professional name of earwax secreted in the human ear canal is cerumen, which is secreted by the cerumen gland in the ear canal, and normal cerumen is protective for the ear canal. 2. The cerumen in the ear canal is divided into dry, oily, and mixed. People often say that his ear canal is “sugar ear”, which is oily cerumen. In terms of form, there are flakes, lumps, and paste. The ear canal cerumen should be cleaned up once a year, depending on the symptoms and the doctor’s examination. 4. Before swimming, be sure to go to the hospital for your child’s ears to see if there are lumps of cerumen. If not taken out in time, the cerumen will be like a hair bean when it meets water, and the cerumen bubbles up and presses on the ear canal, which is lightly just blocked and affects hearing, and heavily leads to infection, causing inflammation of the ear canal and secondary tympanitis. Remember that parents should not pull out their children’s ears to prevent damage to the ear canal and eardrum, which can affect hearing.
