<bold>Materials and methods:</bold> 150 CBCT images where bilateral maxillary sinuses were scanned were included in the study following the inclusion and exclusion criteria. 75 CBCT scans each of males and females were studied using the Planmeca Romexis software (Version 4.6.2).

The data were subjected to Chi square test using SPSS software to compare and relate gender and site based differences in the occurrence of the anatomical variations.
<bold>Results:</bold> Sinus septa was the predominant variation in both males and females with significantly higher prevalence in females and on the right side. An ethmomaxillary sinus was seen significantly more often in males, while Haller cells did not show any gender based differences in their occurrence. Ethmomaxillary sinus and Haller cells showed no difference in occurrence on the right and left side.
<bold>Conclusions:</bold> Anatomic variations of the maxillary sinuses are a common finding. It necessary for the clinicians to be familiar with these variations to avoid clinical complications especially in cases of implant placements.

Objectives: The knowledge of the normal morphology of the maxillary sinuses and their variations is important for maxillofacial radiologists to achieve a better evaluation and delineation of pathologies and for pre-implant evaluation of the maxilla.
The aim of our study was to evaluate anatomical variations of maxillary sinuses using Cone Beam Computed Tomography (CBCT).
Materials and methods: 150 CBCT images where bilateral maxillary sinuses were scanned were included in the study following the inclusion and exclusion criteria. 75 CBCT scans each of males and females were studied using the Planmeca Romexis software (Version 4.6.2). Multiplanar images were searched for the presence of anatomical variations such as septae, haller cells and ethmomaxillary sinus. The data were subjected to Chi square test using SPSS software to compare and relate gender and site based differences in the occurrence of the anatomical variations.
Results: Sinus septa was the predominant variation in both males and females with significantly higher prevalence in females and on the right side. An ethmomaxillary sinus was seen significantly more often in males, while Haller cells did not show any gender based differences in their occurrence. Ethmomaxillary sinus and Haller cells showed no difference in occurrence on the right and left side.
Conclusions: Anatomic variations of the maxillary sinuses are a common finding. It necessary for the clinicians to be familiar with these variations to avoid clinical complications especially in cases of implant placements.
