The mandibular position with respect to
the cranial base affected the oropharyngeal airway space, which was smaller in
Class II patients than in Class I and Class III patients. After orthognathic
surgery, the mandibular bone, tongue, hyoid bone, and epiglottis move backward,
resulting in narrowing of the pharyngeal airway space. Therefore, patients
require postural adaptations to get accustomed to a narrow airway. The aim of
the present study was to investigate the correlation between changes in the
head posture and pharyngeal airway space after mandibular setback surgery.
