Correlation between maxillary sinus volume and different facial patterns using Cone Beam Computed Tomography in adults

Introduction: The maxillary sinus both affects and is affected by orthodontictreatment thus knowledge about it is of great value. With the emergence of Cone-beamcomputed tomography (CBCT) studying the maxillary sinus became more accurate.Aim: to find out if there is a correlation between the maxillary sinus volume andfacial pattern in adults using cone beam computed tomography. Methods: Cone-beamcomputed tomography (CBCT) scans of 36 adults were obtained. They were dividedequally into three groups: Normal facial pattern, hyper-divergent facial pattern andhypo-divergent facial pattern. The volume of the maxillary sinus on both the rightand left sides were measured in each group using OnDemand3D software program.Results: The results of this study were that there is no significance differencebetween the maxillary sinus volume in the different groups of facial pattern. There isno significance between the volume of the maxillary sinus on the right and left side.Conclusions: There is no correlation between the maxillary sinus volume and thevertical growth pattern. The right and left maxillary sinus are corresponding to eachother in volume.
