Background: The quality and discrimination of sound depends on the shape of the pinna. The auricle exhibits wide variations particularly in its shape and the rolling of helix to such an extent that right and left ears of an individual differ. Aim: To determine different shapes of the external ear and the degree of concavity of helix. Materials and methods: 90 dental students participated in the study after an informed consent. The external ears of both sides were observed for variations in the shape and rolling of helix. The results were tabulated and compared with other studies. Results: Oval shaped external ears were the most common forms observed, 58.33% in males and 58.97% in females. The values were compared with other studies and the decreasing order of frequency of ear shapes was oval, triangular, round and rectangular. The concavity of helix was studied. 66.66% males and 60.25% females possessed normal helix followed by wide helix covering scapha, flat helix and concave marginal helix in that order in males but females possessed concave marginal helix in more numbers as compared to wide helix covering scapha. Conclusion: The four different shapes of the external ear were oval, triangular, round and rectangular in the decreasing order of frequency. Oval shape is the most common as correlated with other studies. Four varieties of rolling of helix were observed -normal rolling, wide concavity covering scapha, flat helix and marginal concavity helix. The order of frequency showed gender variation.
