Pediatric snoring during sleep used to be considered by parents as a sign that their children were sleeping well, and some parents were proud of this, believing that their children were in good health. Modern scientific research has proven that snoring, open-mouth breathing and even apnea during sleep is a disease state. If left untreated, it can lead to long-term chronic oxygen deprivation in children’s brain, which can lead to daytime irritability, irritability, reduced attention span, poor mental health and drowsiness, etc. Over time, it can even cause changes in facial shape, which seriously endangers children’s growth and development and physical and mental health. Pediatricians suggest that the main causes of such diseases in children are adenoid (proliferative) hypertrophy, tonsillar hypertrophy, congenital small jaw, small pharyngeal cavity, excessive obesity, and some neuromuscular pathologies. However, the need for treatment and the choice of treatment for children with these symptoms is determined by a series of tests and a specialist’s visit.
