Childhood obstructive sleep apnea (OSA) has a striking prevalence of approximately 2 to 4 %. Milder precursors, such as primary snoring, are more common. Their combined prevalence amounts to about 10 %. Primary snoring may develop into full-blown OSA and thus constitutes a preliminary stage of the disease. Orthodontic treatment can positively affect the expression of OSA. In many cases, it can eliminate the underlying craniofacial disharmony, which narrows the posterior airway space (PAS), and increases the PAS at the nasopharyngeal and oropharyngeal levels. Supportive myofunctional therapy promotes correct ventral and cranial tongue positioning and thereby increases the oropharyngeal airway space.
