Influence of myofunctional therapy on oropharyngeal airway dimensions in skeletal class II cases - a cephalometric study

Skeletal Class II malocclusion is associated with a multitude of functional problems one of which is reduced oropharyngeal airway dimension. The airway is receiving renewed attention in recent literature regarding snoring and obstructive sleep apnoea syndrome especially as a retrognathic mandible is often implicated as its cause. The study was undertaken to investigate the myofunctional appliance (TWIN BLOCK) effects on the oropharyngeal airway dimensions in Skeletal Class II individuals in the average age of 11-13 years. This study also expresses the existence of any correlation between airway dimension and craniofacial morphology.
