Many parents think that their children snore because they sleep well. In fact, it is not. Medically speaking, snoring in children is also called “obstructive sleep apnea syndrome”. The clinical manifestation is nasal congestion, sleep snoring, open-mouth breathing, and lack of oxygen due to breath-holding, which makes children toss and turn and sleep restlessly. 2002 questionnaire survey of 28,484 children aged 2 to 12 in 8 cities nationwide showed that the incidence of sleep disorder symptoms in children was 27.1%, and the most common one was “obstructive sleep apnea syndrome”. The most common is “obstructive sleep apnea syndrome”, with an estimated incidence of 3%. Why do babies snore? The vast majority of clinical findings on the causes of snoring in children are due to enlarged tonsils and adenoids. The adenoids and tonsils are the lymphoid tissues of the upper respiratory tract. With low immunity and susceptibility to upper respiratory tract infections in childhood, often one or more colds will cause the adenoids or (and) tonsils to grow and hypertrophy, after which the cold gets better but the adenoids or (and) tonsils do not shrink. The enlarged tonsils and adenoids cause varying degrees of obstruction in the child’s young upper respiratory tract, resulting in poor breathing and snoring. It is as if two heavy trucks are now blocking the originally clear road, creating a traffic jam. What are the dangers of snoring? First of all, growth hormone, which promotes the growth and development of children, is mainly secreted at night in the state of deep sleep. The clinical findings show that the growth hormone level in the body of children with severe snoring is low, and these children will generally appear short, some data show that normal children can grow 5-7 centimeters a year, but snoring children may only grow one or two centimeters a year, or even no growth. At the same time, children’s nervous system is in the developmental stage, very sensitive to oxygen deprivation, lack of oxygen to the brain will lead to children’s inattention, hyperactivity, grumpiness, and even affect the intellectual development. Secondly, due to children’s nasal congestion and long-term open mouth breathing, under the impact of airflow, the hard palate will be high arched, which will make the facial development deformation, the upper lip is short and thick, the lower jaw is drooping, the nasolabial fissure disappears, the upper incisors protrude, and the bite is poor, which is medically called “adenoid face”. In addition, the enlarged adenoids also tend to block the posterior nostrils, long-term nasal congestion, which may further cause chronic rhinitis and sinusitis. The enlarged adenoids also compress the pharyngeal orifice of the eustachian tube, causing non-suppurative otitis media, which in children can manifest as ear discomfort, loud TV viewing, and sometimes ignoring adult shouts. Nonsuppurative otitis media is an important cause of deafness in children. What should parents do? Parents should observe whether their child snores frequently during sleep, likes to sleep on his or her stomach, struggles to inhale, breathes with an open mouth, opens and closes his or her nose, and has depressions between the ribs and on the sternum. If so, it is necessary to seek medical consultation as soon as possible. Since the cause is clear, once the diagnosis is confirmed, early surgery is advisable. Cryo-plasmapheresis of the tonsils and adenoids is a highly effective and minimally invasive procedure that aims to give the child a clear upper airway so that the baby can sleep soundly and grow healthier.
