When children have lesions of the adenoids and are operated on in a regular hospital, they are usually harmless. If the postoperative care is not adequate, then the main harm is that it affects the recovery of the organism. Some of them may experience a decrease in immunity. When a child has uncomfortable symptoms caused by enlarged adenoids or other serious adenoidal lesions, he or she can seek medical attention for treatment through adenoidal surgery. If the child is operated in a regular hospital, and if he or she is thoroughly examined before surgery, checked for contraindications, and taken care of after surgery, the surgery is usually harmless and parents do not need to worry too much. If children have contraindications to adenoid surgery or do not pay attention to postoperative wound care, the main hazards are complications such as infections, damage to the function of the eustachian tube, incomplete resection or hyperplasia, and unrelieved symptoms, which will affect the quality of life and health of the child. In order to reduce the harm of surgery, parents should pay attention to wound care after surgery and closely monitor the vital signs of children. Since adenoids have certain immune function, children with young age may have some degree of immunity decline after the resection. It is recommended that children in need of adenoid surgery should choose to undergo surgery at a regular hospital to minimize the risk to the body.
