Drug treatment: For all types of rhinitis and rhinosinusitis with adenoid hypertrophy, the adenoids can be moderately reduced in some patients after 1-2 courses of standardized comprehensive drug treatment and inflammation control. The standardized comprehensive drug treatment includes: 1. Types of drug treatment: antibiotics – according to the needs of the disease, choose intravenous drip or oral penicillin group and pioneer group of antibiotics. Proprietary Chinese medicines – various types of proprietary Chinese medicines for rhinitis, such as: smooth nasal pellets, nasal abnormalities and orifices pellets, Xiangju tablets, Zhonglian rhinitis tablets, nasal abyssal shu oral liquid, etc. Promote mucous membrane excretion – such as: standard myrtle oil. Anti-allergic drugs – loratadine, montelukast, etc. 2. Duration of medication: natural regression of inflammation, in smooth cases, also takes 2 weeks, therefore, medication should be a course of 15 days. Of course, if the child can cooperate and use saline to rinse the nasal cavity every day, or if conditions allow, use suction to remove nasal secretions every day, the effect will be better. Surgical treatment: The enlarged adenoids can be appropriately reduced by medication, but not all of them can be treated satisfactorily by medication. After 1-2 courses of standardized comprehensive drug treatment and inflammation control, if the proliferating body still exceeds 2/3 of the cross-sectional area of the posterior nostril and is accompanied by ventilation disorders, surgical treatment should be considered. Surgical method: At present, the most recommended surgical method is transoral proliferator resection under general anesthesia with a power cutting system. The advantages of this surgical approach are: 1. Under direct nasal endoscopy, the entire surgical operation can be seen at a glance. 2.Using the power cutting system, the whole surgical procedure is completed in one go. 3, the use of electrocoagulation to stop bleeding, more safe and reliable after surgery. The details are as follows: under general anesthesia, the hypertrophied or/and inflamed tonsils are first removed, and after sufficient hemostasis, a pediatric catheter is inserted through each side of the anterior nostril, which is led from the mouth and the soft palate is pulled up. Under direct transoral 70-degree nasal endoscopic view, the adenoids were removed sequentially from the edge of the adenoids toward the midline using a power cutting system with suction.
