The child’s sleep snoring may be a sign of sleep breathing disorder, the light can affect the child’s intelligence and physical development, serious can cause sudden death during sleep, parents must pay attention, timely understanding of the causes, for targeted treatment. The causes of child snoring 1, obesity: fat baby pharynx soft flesh structure is thicker, when sleeping oropharynx airway easy to block, snoring, and in serious cases, even apnea phenomenon. 2. Narrow nasal passage: The baby’s pharyngeal cavity is short and the nasal passage is narrow, so the slightest secretion or mucous membrane swelling will easily block it. Small babies within half a year old often have nasal sound, nasal congestion or phlegm sound in the throat, is the cause of this. 3, respiratory tract inflammation: inflammation of the upper respiratory tract, chronic sinusitis will make the nasal mucosa congestion edema, as well as tonsillar proliferators abnormal hypertrophy, nasopharyngeal ventilation obstruction, sleep can not breathe through the nose, with breathing snoring sound. 4, tonsil adenoid enlargement: during infancy, the baby’s pharynx collects rich lymphoid tissue, also known as proliferative bodies, hyperplasia is proliferative hypertrophy, tonsils or proliferative gland hypertrophy, causing narrowing of the throat, snoring when sleeping, resulting in snoring, open-mouth breathing and even apnea. Snoring in children’s sleep may cause malnutrition, and can cause ear disease, and in serious cases, can also cause a decline in intelligence, resulting in children’s inattention, academic performance decline, and more serious consequences are sudden death due to apnea during sleep. Parents must pay attention to children snoring, and promptly choose a regular professional hospital for examination and treatment. The first three causes can be avoided or improved, but once tonsillar adenoid enlargement occurs, conservative treatment is difficult to cure, only surgical treatment to achieve the effect of airway patency, now our department for children with nasopharyngeal cavity physiological structure and nasopharyngeal function development needs, the introduction of the most advanced imported plasma ablation equipment, with small trauma and fast recovery characteristics. It minimizes the damage to the mucous membrane, is minimally invasive and bloodless, and has high safety. Its treatment principle is to use the energy of low-temperature plasma radio frequency to ablate the diseased tissue in the pharyngeal cavity with the plasma low temperature of about 40 degrees to restore the normal ventilation of the pharyngeal cavity.
