If children snore at night, especially if they snore heavily, their sleep is often interrupted and they do not get a good rest at night, so their spirit and appetite are poor during the day, and they do not take in enough calories, which leads to stagnant growth, and their height and weight are lower than those of normal children in the same year. In addition, some experts believe that these sleep snoring children have acidosis at night, and the hypoxia caused by poor breathing or apnea during heavy snoring makes the body suffer from hypoxemia and hypercarbia, the latter two also make the pulmonary artery and systemic artery pressure rise and overload the heart. The cause of pediatric sleep snoring is often tonsillar hypertrophy and adenoid hypertrophy. Enlarged tonsils can interfere with breathing and sleep. Perhaps such tonsils have never been inflamed, but the hypertrophied tonsils cause narrowing of the pharynx, so that children are slow to eat, have coarse out-breathing when quiet, pant at the slightest activity, snore at night after falling asleep, breathe with open mouth, hold their breath, and sometimes not even breathe for 1 to 2 minutes and experience apnea. This long-term lack of oxygen can affect the growth and development of the child. Although the tonsils are an immune organ of the body, at this time their harm has outweighed their benefit, so they should be removed to relieve the obstruction. Adenoids, also known as pharyngeal tonsils and proliferators, are located in the posterior wall of the nasopharyngeal apex. The adenoids are present after birth and are largest at the age of 6-7 years, and generally shrink gradually after the age of 10, stopping at the age of 14. Physiologically, the adenoids are also immune organs, but they play a smaller role than the tonsils. In the case of adenoid hypertrophy, it can easily lead to some symptoms of the ear, nose, throat and respiratory tract, such as secretory otitis media (manifested as hearing loss and unresponsiveness). In severe cases, “adenoid face” may appear, causing some systemic symptoms and delayed growth and development. According to the analysis of clinical observation data, the main reason for consultation is night snoring or/and open-mouth breathing. If these symptoms are present, active surgical treatment is required if contraindications to surgery can be excluded. Therefore, parents should pay enough attention to pediatric sleep snoring and go to the hospital as soon as possible. Once the tonsillar hypertrophy and adenoid hypertrophy are clearly diagnosed by the ENT doctor, they should be surgically removed in time. After the operation, the snoring phenomenon and related symptoms can be eliminated quickly and the growth and development can be restored to normal.
