Children with enlarged tonsils and adenoids who wore an oral appliance for six months experienced more favorable craniofacial growth, enlargement of pharyngeal dimensions, and improved breathing and snoring during sleep, according to new research that will be presented Saturday, June 11, at the 20th Anniversary Meeting of the American Academy of Dental Sleep Medicine (AADSM).
Enlarged tonsils and dental malocclusion have a strong relation with sleep disturbance in children. Its consequences can include abnormalities of craniofacial growth and facial morphology more suitable to the development of obstructive sleep apnea (OSA).
Forty children from the waiting list for adenotonsillectomy at the ENT Department of the University of São Paulo Medical School were included in the study. The children ranged from 6 to 9 years of age. All of them presented snoring, tonsil and adenoid enlargement grades III and IV, and dental malocclusion (constricted maxilla and/or jaw deficiency). Patients were divided into two randomized groups: 24 patients were treated with the Bioajusta X dental appliance and 16 were controls.
The researchers evaluated the craniofacial growth in children with enlarged tonsils and adenoids, after dental appliance (Bioajusta X) treatment. They also compared the prevalence of snoring before and after treatment.
"The primary finding of the study was the positive influence of this treatment on snoring in children with enlarged tonsils and adenoids and narrow maxillary arch," said principal investigator Walter R. Nunes Jr., DDS, MS, who is affiliated with the Otolaryngology Department of the University of São Paulo Medical School in Brazil.
