Snoring or snoring is a common phenomenon in life. If the loudness of snoring increases more than 60dB after the patient is asleep, which hinders the gas exchange during normal breathing, it is medically called snoring, and about 5% of snoring patients also have different degrees of breath-holding phenomenon during sleep, which is called obstructive sleep apnea syndrome. Snoring in children is mainly due to the repeated inflammation of adenoids and tonsils causing hyperplasia and hypertrophy, resulting in narrowing of the airway, and when the inhaled airflow hits the narrow mucosal edge or the secretion on the mucosal surface, a vibration is produced and the snoring sound we hear is formed. Children snoring evidence is mainly judged by clinical symptoms. Clinical manifestations: ① Severe snoring, breath-holding, nocturnal apnea, sleepwalking, urine loss and daytime sleepiness. ②Whether the child has open-mouth breathing at night, snoring and breath-holding during sleep, always moving around during sleep, even waking up and crying, and whether it is accompanied by urine loss. (③) Are there any symptoms such as inattention, hyperactivity, growth retardation and recurrent upper respiratory tract infections during the day? Through these, we can initially determine whether the child is suffering from snoring evidence. As children grow older, their immune function is gradually replaced by other organs. Adenoids are most prominent when children are 6-7 years old, and gradually shrink after 10 years old. In adults, only a small amount of residual tissue remains and it is no longer an immune organ. The tonsils are the largest pharyngeal lymphoid tissue. At the age of 3 to 5 years, the lymphoid tissue proliferates and the tonsils may become physiologically enlarged, and then gradually atrophy in adulthood. Clinical studies have shown that the number of adenoids and tonsils that do not atrophy is increasing. Snoring affects the growth and development of children During the growth and development of children, each stage is valuable and irreducible, so the far-reaching impact of snoring on the whole physical and mental health of children cannot be ignored. First, it affects the normal development and learning of children. When children snore seriously, it leads to apnea during sleep, resulting in lack of oxygen to the brain and CO2 retention, and when the brain is not supplied with enough oxygen for a long time, the cortical function of the brain will be damaged, which in turn affects the intelligence. If children snore at night and have inattentiveness in class, drowsiness, memory loss and poor academic performance. Secondly, it affects the growth and development of the body. The sleep breathing disorder caused by snoring is very harmful, which will cause the change of sleep time, interrupt the continuity of sleep and reduce the quality of sleep. Once the quality of sleep decreases, the release of hormone will be reduced, which will affect the development of children, such as short size. Thirdly, children snore mainly because of nasopharyngeal and pharyngeal obstruction. When they sleep, in order to ensure normal breathing, children open their mouths to breathe, and their upper and lower teeth bite together abnormally, resulting in facial deformities, causing the typical “adenoid face” such as small jaw deformity, uneven teeth, long maxilla and high cheekbones. Fourth, chronic tonsillitis, adenoiditis, as a chronic infection foci, can also lead to other systemic diseases, such as rheumatic fever, myocarditis, nephritis, bronchial asthma, bronchitis, etc.. Severe adenoid hyperplasia can cause exudative otitis media if the nasopharynx is blocked by the pharyngeal orifice of the eustachian tube, resulting in symptoms such as stuffy feeling in the ear, tinnitus and hearing loss, etc. If the nasal passage is blocked and the drainage of nasal secretions is obstructed, sinusitis can occur as a complication. Children’s snoring should be detected and treated early. First of all, the nasopharynx and tonsils should be checked in the department of otorhinolaryngology, and if there is any abnormality, further corresponding examination and treatment should be carried out, while paying attention to the balance of diet and keeping regularity of work and rest time. Clearly diagnosed as children snoring can be treated through surgery, which is not complicated in medicine. The usual treatment is to surgically remove the abnormal enlarged part of the respiratory tract to make the breathing unobstructed, such as: using tonsils and adenoid hypertrophy (nasopharynx) to remove the apnea phenomenon, so that the child’s memory, intelligence and body and mind can be developed normally.
