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