Snoring in bed is not only for adults, but also for children. Most children snore because of some congenital or acquired diseases, the main reason is tonsil and/or adenoid hypertrophy; others such as rhinitis, sinusitis, deviated nasal septum, nasal polyps, nasal tumors, nasal foreign bodies, jaw and facial deformities, etc. can cause obstruction of the upper airway, thus causing sleep snoring, in addition to excessive obesity can also lead to sleep snoring. Therefore, children’s sleep snoring should never be taken lightly, and the causes should be identified in time and treated in a targeted manner. What are the dangers of children’s snoring: failure to grow taller, loss of IQ, injury to face Children’s snoring, also known as obstructive sleep apnea hypoventilation syndrome, children’s sleep snoring, because the upper airway is affected by enlarged tonsils and/or adenoids, narrowing the upper airway, will cause the affected children to sleep apnea (breath-holding), lack of oxygen, due to sleep can not enter the deep sleep period, growth hormone secretion is insufficient, will lead to The growth and intellectual development will be delayed, and the child will have poor concentration in class during the day, strange personality and reduced academic performance; the hypertrophic proliferators can also block the opening of the eustachian tube due to the compression of the adjacent eustachian tube while causing snoring, which will lead to the child repeatedly suffering from exudative otitis media and affect the child’s hearing. It may also lead to facial deformity development. Long-term airway obstruction may also lead to hypertension and coronary heart disease. Parents must develop the habit of observing their children’s sleep for early detection and early treatment. Adenoid face: Because the nasopharynx of children is relatively small, when adenoid hypertrophy, due to nasal congestion affects breathing and mouth open breathing, long-term breathing with the mouth, airflow impact on the hard palate will make the hard palate deformation, high arch, over time, facial development will be deformed, the upper lip short thick cocking, jaw bone sagging, nasolabial fissure disappeared, hard palate high arch, teeth alignment is not neat, upper incisors protrude, poor bite, nasal septum flat curvature, etc. The facial muscles are not easy to move and lack of expression, which is called “adenoid face”. Diagnostic criteria of snoring in children: 1. Snoring, open-mouth breathing or breath-holding during sleep. 2. Tonsillar hypertrophy ≥ II° narrow pharyngeal cavity. 3.Proliferative hypertrophy (adenoid thickness/nasopharyngeal cavity width ratio ≥ 0.65). Sleep monitoring is considered to be the “gold standard” for the diagnosis of obstructive sleep apnea hypoventilation syndrome in children. Treatment of snoring in children 1. Non-surgical treatment includes medication, postural therapy and transnasal continuous positive pressure ventilation. The adenoids are proliferating at the age of 2-6 years and gradually shrink after the age of 10 years. As age increases, the adenoids will gradually shrink and the condition may be relieved or the symptoms may disappear completely. For the treatment of simple snoring and mild to moderate childhood obstructive sleep apnea hypoventilation syndrome, conservative treatment can be chosen. Apparatus treatment: a. Stop snoring apparatus treatment: simple to use, effective and without any side effects; b. Ventilator treatment: less painful and can improve the sleep quality of children, but expensive and inconvenient to carry; c. Continuous positive pressure ventilation machine: suitable for patients with moderate to severe snoring. Other treatment: 1), weight loss: appropriate exercise to enhance resistance, pay attention to a balanced diet and avoid excessive obesity caused by overnutrition. Obesity is one of the factors causing pharyngeal stenosis, and weight loss can reduce the degree of airway obstruction. 2) Side lying position and choosing a suitable pillow: Let children take side lying position when sleeping. Sleeping in side lying position has the ability to prevent the tongue root from falling back and reduce the degree of upper airway obstruction, which can significantly reduce snoring and apnea. Children who snore should choose a pillow that is not soft or hard, too soft pillows are too elastic and easy to make the neck lose support, which can lead to poor breathing in children. 3), try to avoid colds. 4), with nasal hormones and leukotriene receptor antagonists (cisplatin) on adenoid hypertrophy has been proven to be effective, the course of treatment for at least 8 weeks. If accompanied by rhinitis and sinusitis, it should be treated at the same time. 2. Surgical treatment: The data of sleep monitoring can help to decide whether to treat surgically. For children with moderate or severe snoring, adenoidectomy or tonsillectomy is the treatment of choice. Different surgical methods should be used according to the plane of obstruction. For example, children with nasal obstruction undergo nasal surgery to open up the nasal passage and reduce snoring. Children with pharyngeal stenosis can undergo uvulopalatopharyngoplasty, which is the most common surgical method to treat snoring and sleep apnea by removing part of the uvula and tonsils to increase the septum of the pharynx. If it is caused by enlarged tonsils or adenoids, it is mostly treated by removing tonsils and/or adenoids, and the efficiency can reach 90%.
