RELATION BETWEEN SAGITTAL POSITION OF THE MANDIBLE AND PHARYNGEAL AIRWAY VOLUME IN ADULTS USING CONE BEAM COMPUTED TOMOGRAPHY

Introduction: Many authors have discussed the relationship between craniofacial morphology and pharyngeal airway spaces in different malocclusions skeletal patterns. So aim of this work was to study relation sagittal position mandible volume adults using CBCT. Materials And Methods:Twentyone CBCT radiographs were collected from archive Radiology Department at Suez Canal University divided into 3 groups according measured SNB angle. Group 1 normal mandibular position, group 2 retrognathic prognathic mandible. Dolphin 3D imaging software used measure for all radiographs. Nasopharyngeal, oropharyngeal, hypopharyngeal total volumes F-test (ANOVA) comparison Tukey test pairwise comparisons. Correlations variables tested PearsonÂ’s correlation coefficient. Results: there statistically significant difference mean oropharyngeal three groups. Nasopharyngeal had non-significant There a positive (mm3) Conclusion: Pharyngeal differs with positions decreases retrognathism increases prognathism.
