Every day, some children come to the clinic because of prolonged cough, open-mouth breathing, snoring, headache, fatigue, inattention, urine loss, sleepwalking at night, etc. Many of them are examined because of adenoid tonsillar hypertrophy, but some parents do not pay attention to it, and if it is not treated in time, it can be very harmful to the child. It is possible to diagnose tonsillar hypertrophy by physical examination, and adenoid hypertrophy needs to be diagnosed by x-ray examination. Pathological hyperplasia occurs due to repeated stimulation of inflammation for some reason causing nasal congestion, open-mouth breathing, sleep snoring, coughing, and breathing difficulties. In severe cases, respiratory suspension may occur. When children with such symptoms should go to a regular hospital for early examination and get timely treatment to avoid misdiagnosis and delayed treatment. The main causes of tonsillar adenoid hypertrophy: The common causes of tonsillar adenoid hypertrophy are inflammation such as inadequate treatment of upper respiratory tract infections, acute and chronic rhinitis, and recurrent episodes of influenza, which cause pathological hyperplasia of the tonsillar adenoids. This leads to increased nasal obstruction, obstructing nasal drainage, and sinusitis secretions stimulating the adenoids to continue to proliferate, forming a vicious circle of mutual causation. The harm of tonsillar adenoid hypertrophy: 1, tonsillar adenoid hypertrophy if not treated in a timely manner, not only will affect the occurrence of other ear, nose and throat diseases, and the growth and development of children will also cause a great impact, but also affect the child’s learning and life, the main harm are the following aspects: 2, tonsillar adenoid hypertrophy easily formed “adenoid face “Because the children’s nasopharynx is relatively small, when adenoid hypertrophy, nasal congestion affects breathing and long-term breathing with the mouth, airflow impact on the hard palate will make the hard palate deformation, high arch, over time the development of the face will be deformed, the upper lip short thick cocked, the lower jaw sagging, upper incisors protruding, etc., look very much like a pig or ugly duckling, medically known as ” adenoid face”. 3, tonsil adenoid hypertrophy caused by hearing loss, easy to cause hair ear disease: due to adenoid hypertrophy caused by the nose blockage, resulting in upward drainage of nasal snot, resulting in the pharyngeal tube pharyngeal mouth obstruction, will easily cause secretory otitis media, so that the symptoms of hearing loss and tinnitus. 4, tonsillar adenoid hypertrophy can cause children’s mental imbalance, unresponsiveness: children with long-term mouth breathing, nose ventilation, easy to cause head ischemia, lack of oxygen, mental depression, headache, dizziness, memory loss, unresponsiveness and other phenomena. Adenoid hypertrophy seriously affects children’s growth and development: As children need a lot of oxygen for development, and snoring will make children seriously lack of oxygen during sleep, which directly leads to insufficient oxygen supply for brain development and causes a decrease in secretion of growth-promoting hormone, which not only affects children’s height, but also decreases physical resistance, and will affect children’s future intellectual development. For children with tonsillar adenoid hypertrophy, it is important to cooperate with the doctor to get standardized treatment in a timely manner, and treatment according to the course can often achieve better results.
