The danger of adenoids surgery is that the surgical wound is an open wound, which is fine for adults, but children, because of their younger age and poorer self-control, often cry violently or become emotionally unstable after surgery, which increases the risk of bleeding from the open adenoids wound after surgery, and once it bleeds, it is easy to cause blood to be accidentally inhaled into the airway because it is immediately connected to the airway, resulting in the risk of fatal asphyxia. Therefore, adenoids surgery should be strictly and carefully selected and coordinated with the advice of the ENT surgeon, and the child should recover as quietly as possible after surgery in order to reduce the risk of bleeding and the risk of asphyxia from airway blockage after bleeding. The adenoids are located at the top of the posterior end of the nasal cavity and are lymphatic tissues with certain immune defensive functions. However, if the adenoids are thick and hyperplastic and affect the total amount of gas intake, or even if the adenoids are enlarged and affect the change of facial appearance, adenoids surgery should be performed.
