1.Onset profile of snoring in children Snoring in children refers to habitual snoring and obstructive sleep apnea hypoventilation syndrome that occurs in childhood. Habitual snoring refers to frequent snoring during sleep with uniform snoring sound, no breath-holding, no respiratory arrest, etc. Obstructive sleep apnea hypoventilation syndrome refers to apnea and hypoventilation caused by collapsed upper airway obstruction during sleep, with snoring, sleep structure disorder, frequent blood oxygen saturation drop and daytime drowsiness. Snoring in children can occur in all ages from newborn to adolescence, and the peak incidence is between 2 and 6 years old, with no significant difference between men and women, and the incidence rate varies from 0.7% to 10.3%. The incidence of frequent snoring is 5.7%, and the incidence of sleep apnea is 0.4%. 2.The causes of snoring in children The main cause of snoring in children is adenoid or tonsil hypertrophy, other causes include allergic rhinitis, nasal polyps, nasal septum deviation, posterior nostril stenosis or atresia, giant tongue and small jaw, etc. If your child has the following symptoms, you should be alert to snoring in children: snoring almost every night, open-mouth breathing, restless sleep, frequent breath-holding, excessive sweating, urination, sleepwalking and waking up; headache in the morning, dizziness, dry mouth, easy fatigue or irritability. Daytime fatigue, easy to doze off, lack of concentration in class, hallucinations, hallucinations, decreased academic performance, rebellious or aggressive behavior, developmental delay, language defects, swallowing difficulties, slow eating, etc. 4.How to diagnose children’s snoring mainly based on the above clinical manifestations, physical examination and signs of upper airway obstruction such as tonsil or adenoid hypertrophy, lateral nasopharyngeal film and related examinations suggesting adenoid hypertrophy can make clinical diagnosis, and children who can cooperate can be monitored by all-night polysomnography to further clarify the diagnosis. 5.What are the dangers of untreated snoring in children? If snoring in children is not treated in time, it can have a wide range of effects on the children. Due to the obstruction of airway, the secretion of growth hormone is impaired, which, together with anorexia and swallowing difficulties, can lead to growth retardation; open-mouth breathing can affect craniomaxillofacial development and lead to dental malocclusion. Snoring can affect the cognitive function of children, which can lead to impaired attention, memory loss, lower IQ and lower academic performance. Children with snoring often show hyperactivity, irritability and irritability, and many children also show psychological developmental disorders, such as excessive shyness, depression and poor social adjustment ability. During night sleep, they may show excessive sweating, sleepwalking, night terrors and urine loss. 6, how to treat children snoring mainly according to the cause of treatment. Since the most common cause is tonsillar and adenoid hypertrophy, tonsil and adenoidectomy is the first treatment option. A cure rate of 75% to 100% is usually achieved by removing the tonsils and adenoids. Other adjuvant treatments include weight loss, orthodontics, and positive pressure ventilation on the ventilator. If the child has other diseases such as allergic rhinitis, the treatment should be targeted. 7.Does the removal of tonsils and adenoids affect children? Tonsils and adenoids are lymphoid tissues, which are immunologically active organs of the human body and have a certain resistance to the invasion of germs. However, there is no evidence that removal of the tonsils and adenoids has a significant effect on the immunity of the body. Besides, the benefits outweigh the disadvantages as the airway obstruction is lifted and the general condition and quality of life of the child improve after surgery.
