A typical airway is needed for typical improvement of the craniofacial structures. The objective of the research was to; analyse and contrast the pharyngeal airway volume in the class I and class II facial skeletal patterns using cone beam computed tomography.
Methods: The present retrospective study was led on 80 cone beam computed tomography (CBCT) records of adult egyptians ranging in age from 20-40 years. The records were equally divided into 2 groups; group I (G1) skeletal class I ANB =1°-4°), (group II, skeletal class II (G2) ANB >4°). Evaluation of the pharyngeal air way space volume was conducted and statistically analyzed to contrast between G1 and G2
Results: Statistically significant distinctions was found on total pharyngea1 airway volume between G1&G2
Conclusion: The entire volume of pharyngea1 airway space was much larger in G1 than G2 subjects.
