During outpatient emergency visits, we often encounter children complaining of ear pain, and when asked about their medical history, they often have symptoms such as colds and runny noses. The mother says, “He just keeps running and blowing his nose!” I don’t know, but ear pain is a cold and otitis media caused by improper nose-blowing. As we all know, when you have a cold, there will be a lot of secretions in the nasal cavity, resulting in nasal congestion, nasal mucus and poor breathing. Many patients (not to mention children) can’t wait to blow their noses clean at once, so they blow their noses as hard as they can. However, they do not know that there is a way to blow the nose, and wrong nose blowing can lead to otitis media. When you blow your nose hard, the pressure in the nasal cavity increases suddenly, and the nasal cavity is connected to the middle ear through the eustachian tube, so the purulent secretions and germs in the nasal cavity can be squeezed into the middle ear cavity through the eustachian tube in an instant, causing middle ear infection and resulting in symptoms such as ear pain and stuffiness. Especially for those who have mild symptoms of earache, mistakenly thinking that it is just a cold symptom (coupled with the child’s inability to speak) and delaying the treatment, it can seriously lead to hearing loss, tympanic membrane perforation, and even long-term pus flow from the ear. So how can we avoid otitis media caused by cold and nose blowing? First of all, parents should teach their children the correct way to blow their nose. Take a breath, then gently press one nostril with one finger, and then blow the air out of the other nostril slowly, paying attention to gentle and slow movements and not too much force. Blow both sides of the nose in turn, never pinch both sides of the nose at the same time to blow. In addition, after a cold, pay attention to adequate rest, drink more water, eat more liquid food, spray the nasal cavity with light salt water, etc.. If necessary, you can find an ENT doctor to do local treatment for your child, such as using negative pressure suction to clear the pus nasal discharge, so that your child’s nose can be cleared quickly and he can breathe fresh air.
