According to new research being presented at the 20th Anniversary Meeting of the American Academy of Dental Sleep Medicine (AADSM), 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. 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).
