A Study on the Evaluation of Pharyngeal Size in Different Skeletal Patterns: A Radiographic Study.

Aim: The aim of this study was to evaluate the upper and lower pharyngeal airway dimensions were affected by different skeletal malocclusions.

Materials And Methods: Lateral cephalograms of 120 subjects were used to measure the pharyngeal airway and were divided into three groups (each group included 40 subjects) according to ANB angle: Class I (ANB angle 2° ≤ ANB ≤ 4°), Class II (ANB angle(ANB ≥ 6°), and Class III (ANB angle ≤ 0°). Various linear cephalometric airway measurements (14 measurements) were used to evaluate pharyngeal airway at various levels.
