Children’s noses that are non-ventilated and runny can be treated with Compound Menthol Nasal Inhaler, which can effectively reduce the symptoms of a child’s runny nose and nasal congestion. After using the medicine, parents are advised to observe the changes in the child’s condition, if there is obvious improvement, it is recommended to continue to apply, but if the nose is still runny and not ventilated, it is often necessary to go to the hospital for further examination, improve the anterior rhinoscopy or nasal endoscopy, and even include the side of the nasopharynx. This can clarify the specific situation inside the nasal cavity, and clarify whether there is adenoid hypertrophy. In case of rhinitis, pediatric rhinitis tablets can be applied, and in case of combined adenoid hypertrophy, spraying mometasone furoate nasal antifreeze in the nose is recommended. If the hyperplasia is severe, surgery is often required, so parents are advised to keep a close eye on their child’s condition.
