The adenoid face is a face with a lack of expression due to adenoid hypertrophy that leads to impaired facial bone development, long jaws, high arched palate, uneven teeth, protruding upper incisors, and thick lips, which can also become a “dementia face”. Adenoids are commonly known as pharyngeal tonsils. The normal pharyngeal tonsils develop to their maximum size at the age of six and then gradually begin to degenerate. If the pharyngeal tonsils are enlarged to the point of affecting the surrounding tissues and causing some symptoms, it is called adenoid hypertrophy. If the adenoids become pathologically enlarged and hypertrophied due to repeated stimulation by inflammation, the growth and development of the child is affected. As the nasopharynx of children is relatively small, when the adenoids are enlarged, due to nasal congestion affects breathing and open mouth breathing, long-term mouth breathing, airflow impact on the hard palate will make the hard palate deformation, high arch, over time, facial development will be deformed, the upper lip is short and thick cocked, the lower jaw sagging, nasolabial fissure disappeared, hard palate high arch, teeth alignment is not neat, upper incisors protrude, poor bite, nasal septum flat curvature, etc., facial muscles The facial muscles are not easy to move, lack of expression, look like a piggyback or ugly duckling, medically called “adenoid face”. Pediatric adenoid hypertrophy can cause the nose to become blocked, causing the child’s nasal snot to flow backwards toward the pharynx, stimulating the mucous membrane of the lower respiratory tract, often causing bouts of coughing and making the child susceptible to bronchitis. In addition, children with adenoid hypertrophy are likely to suffer from ischemia and hypoxia in the head due to long-term mouth breathing and lack of ventilation in the nose, resulting in mental depression, headache, dizziness, memory loss and slow reaction. The proliferation of proliferators makes the passage of airflow in the respiratory tract narrow and unobstructed, and the gas strikes the root of the tongue and the hanging congestion and other tissues from time to time during sleep, resulting in a burst of snoring with breathing. As children need a lot of oxygen for development, snoring will make children seriously lack of oxygen during sleep, which will directly lead to the lack of oxygen supply for brain development and reduce the secretion of growth-promoting hormone, which will not only affect the height of children, but also reduce the body resistance and affect the intelligence of children in the future. Therefore, such children are not only prone to respiratory infections, but also prone to chicken chest, funnel chest, and even induce pulmonary heart disease. Therefore, snoring in children has more harmful effects than adults. Long-term airway obstruction leads to poor lung expansion and poor lung ventilation, which easily causes elevated pulmonary artery pressure. The recommended treatment for adenoid hypertrophy is surgery or a combination of Chinese and Western medicine. If the child is older (over five years old) and has heavy symptoms, especially if he or she has respiratory symptoms and snores all year round, then it is very unlikely that adenoid hypertrophy will heal on its own, so the sooner surgery is performed, the better, because conservative treatment is slow and the symptoms themselves have a great impact on the child’s development, and continuing in this situation may affect the child’s normal development with irreversible consequences. Nowadays, adenoidectomy is very safe and fast. If the patient can cooperate well, simple adenoidectomy (local anesthesia) can take less than 15 minutes, but it is recommended to go to a regular ENT hospital to seek treatment recommendations from a specialist, taking into account the specific situation of each child.
