Abstract

Introduction: The mandibular coronoid process is derived from a Greek word ‘korone’ and described as a triangular piece of flattened bone which projects upwards from the anterior part of the mandibular ramus. However it exists in various shapes and sizes. Recently it is being widely harvested as a graft material by surgeons in many reconstructive surgeries due to easy accessibility and membranous nature. It is also used as a useful anthropological marker in determination of species, sex and age. The present study was undertaken to determine the size of the coronoid process existing in south Indian adult population on both sides and to assess the feasibility of using this knowledge in identification of sexing the afore said population.
Materials and Methods: The study includes 30 male and 30 female mandibles which were collected from various medical colleges. The size of the process was assessed by measuring the height and widths of the coronoid process at its base. Total length of the ramus at the coronoid process was also measured. Results were tabulated and statistically analysed using student paired T test with p?0.05.
Results: The height of coronoid process and the length of the ramus at the coronoid process have significant differences on right and left sides in male and female mandibles and can thus be used as a novel parameter in determination of sex.

Keywords: Coronoid, Mandible, Size, Sex determination, Height, Width.
