The common cause of snoring in children is enlarged tonsils and adenoids (adenoids are a piece of lymphatic tissue located at the back of the nasal cavity). The enlarged lymphatic tissue blocks part of the airway, making the airway narrow for a long time, and the only way to feel smooth is to open the mouth to breathe. The main hazards of children’s snoring: 1, resulting in children’s slow growth Snoring causes a decrease in sleep quality, resulting in a decrease in the release of growth hormone, which affects children’s bone development, such as short size, etc. 2, leading to children’s intellectual development backward snoring will make children in sleep serious lack of oxygen, directly leading to the lack of oxygen supply for brain development, especially from 3 to 6 years old is the fastest growing stage of children’s brain, such as lack of oxygen in the brain will hurt the brain nerve cells, long-term will affect the brain development, so that children’s concentration, focus, IQ than normal children poor. 3. Snoring may affect children’s facial appearance Children snoring due to nasopharyngeal obstruction, open mouth breathing, upper and lower teeth bite abnormal, over time may lead to facial deformity development, the formation of “adenoid face”. 4, causing secretory otitis media If adenoid hypertrophy blocks the pharyngeal orifice of the nasopharynx, it will cause secretory otitis media, and symptoms such as stuffy ear, stuffy ear and hearing loss will appear. Clinical manifestations of children’s snoring: 1. Night: sleep snoring, open-mouth breathing, inspiratory effort, “trigeminal sign”, and even cyanosis of the lips and mouth.
