Evaluation of upper and lower pharyngeal airway in hypo and hyper divergent Class I, II and III malocclusions in a group of Egyptian patients

Conclusions In all groups hyper-divergent growth had narrower airway than normal and hypo-divergent growth. Class III had wider airway than Class I malocclusion. Class I had wider airway than Class II division 1 malocclusion. Lower pharyngeal airway in class II division 1 had the narrowest width in all groups. Lower pharyngeal airway in class III mandibular prognathism had the widest width in all groups. Males have wider pharyngeal airway than females.
