Comparative analysis of upper airway space with lateral cephalogram and cone beam computed tomography in north Gujarat population

Abstract

Objective : The Aim and objective of this study is to evaluate the accuracy of upper airway measurement using with lateral cephalogram , CBCT lateral reconstruction and CBCT axial planes as well as to correlates these finding with area measurements acquired with the latter imaging methods. Methods : In this study , 44 subject (22 males & 22 females) included from north Gujarat adults . Landmark were defined for measurement of naso and Oropharynx , for different planes , using linear antero-posterior measurement and the corresponding area. Result : Analysis of variance shows linear measurement in nasopharynx and oropharynx area wise distribution and Inter Group Wise Distribution in Nasopharynx , all three group have significant different value. In inter Group Wise Distribution in Oropharynx, there is statistically no significant difference between Lateral Reconstruction Group and Lateral Cephalogram Manual Tracing Group. Statistically, no significant difference between Lateral Reconstruction Group and Axial Slice Group & also Statistically, no significant difference between Lateral Cephalogram Manual Tracing Group and Axial Slice Group. Conclusion : The linear measurements of the airway space obtained using the different techniques correlated positively with the respective area measurements, which demonstrate the reliability of the investigated techniques.
