Abstract               Background: The mandibular coronoid process is a thin and triangular eminence which is flat from side to side and varies in its shape and size. Objectives: To study various types of coronoid processes in cadavers at rural tertiary care hospital. Material and Methods: Total of 70 dry mandibles were examined for types of coronoid process in medical colleges of Marathwada region. Results: Out of 140 sides most common type seen in this study was hooked variety (44%), next common was rounded variety seen in 35% cases. In males hooked variety was most commonly seen in 40 (57%) and while in females rounded variety was most common seen in 32(45%) cases. Hook variety was significantly higher in males and rounded coronoid process was significantly higher in female mandibles.(p<0.05), none of the types were associated significantly with either of the sides in any of the gender. But bilaterally similarity in 101 (72%) out of 140 sides in shape was quite notable. Conclusions: Hooked shape was seen as most common variety of coronoid process in this study. Hooked variety in males and rounded variety in females was seen significantly higher than rest varieties.
