Glandular hypertrophy, also called hyperplasia of the proliferators. The glands are already present in the nasopharynx after birth in infants and children. The endolymphatic rings of the human pharynx, including the tonsils bilaterally, the follicles at the root of the tongue, and the adenoids in the nasopharynx. The physiological process of adenoids: they are present after birth and gradually proliferate until the age of 5 or 6 years, when the proliferation reaches its peak. After puberty, the adenoids gradually shrink after the age of 10 or 11. However, for children with repeated upper respiratory infections or tonsillitis, as well as lymphatic reaction, the adenoids will show excessive hyperplasia and hypertrophy, gradually blocking the posterior nostril of the nasopharynx, causing nasal congestion and other symptoms. If the blockage reaches 50-70%, or even more than 75%, it is a severe blockage, which will lead to obvious nasal congestion. Snoring, apnea, open-mouth breathing during sleep, and even symptoms of rhinitis such as recurrent nasal congestion and runny nose can occur. Most children can cooperate in the diagnosis of adenomegaly, which is diagnosed by epharyngoscopy. For children who do not cooperate, CT of the nasopharynx or lateral radiographs of the nasopharynx are then considered, but try to avoid the absorption of radiation in children. If the diagnosis is clear and the symptoms are obvious, the only treatment is surgery. The key whether to do surgery or not depends on the patient’s symptoms.
