Background: The pterygoid hamulus (PH) is a small protrusion on the base of the pterygoid process of the sphenoid bone. PH is a site of insertion of many muscles and ligaments. Its topography can determine predilection for developing the pterygoid hamulus bursitis (PHB). Materials and methods: The study was conducted based on the morphometric analysis of 100 PHs on cone beam computed tomography scans. Results: Based on statistical analysis, we found numerous significant correlations between the morphometric parameters. Conclusions: Considering our results, it can be concluded that the main pathogenic factor in PHB is an extensive medial deviation of the pterygoid hamulus in the frontal plane.
