This study established a system of ventilation condition and the obstruction site specification from a nose to a throat using CT data. From the system, (1) The Class III malocclusion is associated with shape of the oropharyngeal airway. (2) Most dolichofacial children with a Class II malocclusion have an obstructed upper airway. (3) It was useful for a diagnosis and treatment of OSAS and the upper airway obstruction of the maxillofacial malformation person.
