Case: Patient Huang, male, 7 years old. In the past two years, he had repeatedly snored during sleep, with open-mouth breathing and breath-holding; he had intermittent morning headache; his academic performance had decreased in the past two years. After admission, he was found to have uneven teeth, prominent upper incisors and slightly thick lips; his tonsils were enlarged bilaterally with chronic inflammatory congestion on the surface and narrowed oropharynx; a lateral rhinitis film suggested adenoid hypertrophy; fiberoptic nasopharyngoscopy showed that adenoids blocked the posterior nostril by more than 50%. Discussion: Pediatric snoring is a disease that affects the growth and development of children due to enlarged tonsils and adenoids, which leads to narrowing of the airway and can lead to a variety of complications. (2) Snoring means the body is in a state of oxygen deprivation, which may cause intellectual development in the long run; (3) Adenoid face: the upper lip is upturned, the upper teeth are bared, the palate arch is high, and the expression is dull; (4) Secretory otitis media, sinusitis, pharyngitis, etc. may occur in combination. In terms of treatment, regardless of the treatment method, the aim is to open up the airway and correct the body’s lack of oxygen. Currently, the main treatment for this disease is to perform tonsil and adenoidectomy to clear the airway. Compared to traditional surgery, the advantages of plasma surgery include less trauma, less bleeding, and faster recovery for the child. (1) Some parents think that snoring is not a disease, or they think that their children may not snore when they grow up. It should be pointed out that if the affected child has already developed complications such as snoring and breath-holding, learning decline, or sinusitis, or even adenoidal facies, abnormal physical and intellectual development, it means that the body has been obviously affected, and delaying the disease may cause irreversible bad effects. (2) Parents believe that tonsils and adenoids are immune organs and if they are removed, the child’s immunity will be out of order. It is important to note that the tonsils and adenoids can act locally as immune organs. However, there is no conclusive evidence that the immune resistance of the whole body to diseases will be reduced. At present, the indications for surgery are relatively mature. The pros and cons can be fully weighed between preserving local immunity and removing the effects of snoring. (3) Some parents are afraid of surgery because of the young age of the child. At present, medical conditions are better, and the relevant preoperative examination has been done to exclude contraindications to surgery, therefore, there is no obvious risk of surgery in general.
