Abstract

Objectives: Aim of the study was to compare pharyngeal airway dimensions and volume in skeletal class I, class II and class III subjects using CBCT.
Methods: the study sample consisted of 60 patients within the age range 18-35 yrs (34 females and 26 males) divided into 3 groups as group A- class I (0 ? ANB ? 3 ), groups B- class II(ANB >3)? and group C- class III(ANB< 0> Results: The OP volume of class III patients was higher when compared to class I and class II whereas NP volume was higher in class I with statistically significant difference between groups. NP length was higher in class II when compared to class I and class III with statistically significant difference between groups. OP width and most constricted area were least in class II groups with statistically significant difference between class II and class III groups.
Conclusion: Subjects with retruded position of mandible had an effect on OP volume. OP width and most constricted area varied significantly between class II and class III groups with smaller dimensions in class II.
