Core Tip

Core Tip: With the advent of cone beam computed tomography, analysis of airway has become possible. Patients who present with retrognathic jaw or anterior-posterior skeletal discrepancy have been contemplated to have reduced pharyngeal airway. When comparing the airway volumes of 120 healthy individuals with mandibular retrognathism and normal anteroposterior skeletal relationship, the mean total airway volume of patients with the angle formed between point A, Nasion and point B (ANB) more than 4 was significantly smaller than that of patients with ANB less than 4. The sub-volumes in the pharyngeal airway showed a positive correlation with each other. Frankfurt Mandibular Plane Angle and facial convexity and mandibular body length also had a significant interrelationship with total volume of airway.
