Abstract
Pharyngeal airway changes after orthognathic surgery have been
concerned because of the effects on breathing function of the patients.
Moreover, sleep quality of patients can be improved or worsened by these
changes. Obstructive sleep apnea is a disorder characterized by episode of
pharyngeal airway collapse. It may be better following a maxillomandibular
advancement surgery or may be worsened or developed after mandibular
setback surgery. The purpose of this study is to review the changes of
pharyngeal airway and its important related structure such as hyoid bone, the
tongue and soft palate after orthognathic surgery in dentofacial deformity
patients. The change of the head posture, the adaptation and the stability of
the pharyngeal airway are also considered. Moderate evidence was found to
support a significant decrease in the oropharyngeal airway after mandibular
setback surgery. Bimaxillary surgery in class III patients has less unfavorable
effects and should be considered when setback the mandible a large extent.
Maxillomandibular advancement widens the airway in many levels and has
high success rate in treatment of OSA.
