If your child has often runny nose recently, you should promptly lead your child to the hospital to see if your child is suffering from pediatric sinusitis, and if your child is suffering from pediatric sinusitis should be treated promptly so as not to cause other adverse consequences. Sinusitis is a common disease in children, Gu called pediatric sinusitis. Children are less fit compared to adults, have limited self-protection, and are susceptible to colds, which can lead to rhinitis and sinusitis in severe cases without timely and thorough treatment. When a child has a cold, the mucous membrane of the nasal cavity becomes inflamed and if not treated in time, the inflammation of the nasal cavity spreads and invades the sinuses, causing acute sinusitis. Colds are the most important cause of sinusitis in children. The presence of a nasal foreign body, which hinders the drainage of secretions in the sinuses, can also cause sinusitis. If a child has dental caries and the root of the tooth is not treated in time, this can lead to inflammation of the maxillary sinus near the root of the tooth. In addition to nasal congestion and pus, sinusitis in children can be accompanied by fever and cough, depression, irritability, otitis media, rhinorrhea and arthralgia, and in older children, headache. After the formation of chronic sinusitis, occlusive nasal sound and open-mouth breathing occur, and mucus nasal discharge is “inexhaustible”. Chronic nasal obstruction and open-mouth breathing can affect the development of the face and chest, and result in memory loss and decreased academic performance. Since children cannot express their condition accurately, it is easy to delay their treatment. Parents should think of sinusitis if they find that their child has the following conditions: first, symptoms persist for more than 10 days after a cold; second, they suffer from upper respiratory tract inflammation several times a year; third, they have a lot of purulent nasal discharge. Be sure to take your child to a qualified specialist hospital in a timely manner, standardize treatment, and do not abuse drugs on your own to avoid delaying the condition and causing serious effects. The treatment of pediatric sinusitis can be carried out in a variety of ways. The actual intranasal vasoconstrictor can be used, and for those who have metabolic factors, anti-metabolic drugs can be applied systemically. chronic sinusitis in children over 6 years old can be treated with negative pressure replacement therapy. For chronic sinusitis with palatine tonsillar hypertrophy, tonsillectomy should be performed early and scraped together with adenoids. In the case of persistent pediatric sinusitis, septal correction, intranasal windowing of the inferior nasal tract or nasal polypectomy can be considered under strict indications. Remind parents to pay attention to their children’s nasal hygiene, dental disease, to thoroughly treat, strictly prohibit smoking, alcohol, spicy food, swimming posture should be correct, try to do the head exposed to the water, pay attention to the method of blowing snot.
