Children’s sleep snoring is not a trivial matter, the main causes are: tonsillar hypertrophy, adenoid hypertrophy, allergic rhinitis, sinusitis and nasal neoplasia. Sleep snoring in children can lead to damage to the child’s multi-system, due to lack of sleep, growth hormone secretion is reduced, directly affecting growth and development, generally will appear short stature, intellectual development disorders, inattention, irritability and hyperactivity, sleep breath-holding awakening, can also affect the child’s hearing, social skills, etc.; specific hazards are as follows: 1, because the child long-term open mouth breathing, airflow is not through the nasal cavity for heating, humidification and filtration, prone to epiglottis. 1, because of the child’s long-term open-mouth breathing, airflow is not through the nasal cavity for heating, humidification and filtration, prone to upper respiratory tract infections; 2, long-term respiratory problems can make the lungs under-expanded, affecting the normal development of the thorax; 3, adenoid hypertrophy blocking the pharyngeal canal pharyngeal mouth, causing secretory otitis media, resulting in hearing loss, tinnitus, if the secondary bacterial infection, resulting in acute purulent otitis media, can make the child’s hearing further damage. 4. Affect the development of facial shape. About 15% of snoring children have adenoid face, which is characterized by long maxilla, high arch of hard palate, uneven teeth, upper incisors, thick lips and indifferent expression. Therefore, when a child snores in sleep, it is also a “danger signal” and parents need to pay more attention to it, not to think that “snoring” is a trivial matter. For children with sleep snoring, it is important to pay attention to nasal endoscopy and allergen screening to understand the degree of adenoid hypertrophy and rhinosinusitis. For children with sleep breathing disorders, the main procedure is minimally invasive low-temperature plasma surgery under general anesthesia endoscopy to surgically remove the hypertrophied tonsils and adenoids, and to standardize the treatment of concurrent rhinitis and sinusitis.
