When we are in the emergency clinic, we often meet parents who bring their children to the clinic with ear pain. The elders often say, “He (she) just keeps running and blowing his nose!” I don’t know, ear pain is a cold, blowing the nose inappropriate way caused by otitis media! We all have this experience, once the cold, the nasal cavity will produce a lot of secretions, resulting in nasal congestion, nasal mucus, poor breathing symptoms. Many patients (not to mention children) hate to blow their noses clean and ventilate their noses some at once. So they blow their noses as hard as they can. But I do not know that there is a way to blow the nose, and the wrong way to blow the nose can lead to otitis media. The nasal cavity is connected to the middle ear cavity through the eustachian tube at the back, and the purulent secretions from the nasal cavity with bacteria can be squeezed into the middle ear cavity through the eustachian tube in a flash, causing middle ear infection and resulting in ear pain and stuffy ears. The eustachian tube of children is shorter, wider and straighter than that of adults, so it is easier to blow the purulent secretions into the middle ear cavity; especially if the symptoms of earache are mild, the treatment is delayed because of the misconception that it is just a cold symptom (plus the child cannot say), which can seriously lead to hearing loss, tympanic membrane perforation, even long-term pus in the ear, and even complications such as vertigo, facial palsy and meningitis. So how to avoid otitis media caused by cold nose blowing? First of all, parents should teach their children the correct way to blow their nose. You can take a breath, then gently press one finger on one side of the nose, and then blow the air slowly out of the other nostril, 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 the nose. In addition, after a cold, pay attention to adequate rest, drink more water, eat more juicy food, spray the nasal cavity with light salt water, etc.. If necessary, you can find an otolaryngologist to do local treatment for your child, such as using negative nasal pressure suction to clear the pus nasal discharge, so that your child’s nose can be cleared quickly and he can breathe fresh air to prevent acute otitis media.
