There is lymphatic tissue in the nasopharynx after the child is born, and as the lymphatic tissue grows older the range will gradually become larger, resulting in adenoids blocking the posterior nostril, the child will have nasal congestion and runny nose, and prolonged stimulation of the nasal mucosa can easily induce rhinitis in children, which must be actively treated symptomatically. The inside of the nose can be cleaned repeatedly with saline, after which the child can be sprayed with mometasone furoate nasal spray, while the child is allowed to take oral Oronema drops to promote the secretion of the glands, which is conducive to the outward drainage of nasal discharge. If the child’s symptoms do not improve after half a month of conservative treatment, the child can go to the hospital for further examination to clarify the degree of gland blockage, and if necessary, surgery can be performed to solve the problem. Surgery often requires general anesthesia, parents need to have some psychological preparation, normally the treatment can be discharged in about a week.
