Abstract
Aim: To study the morphological details and analyse the morphometry of the External Aperture of carotid canal (AECC) in the base of dry human skulls of mainly Indian population. Methods: 82 dry adult human skulls of unknown sex and of South Indian origin were obtained and variations in appearance of AECC were observed. The length and width of the AECC of both sides were determined using vernier calipers and area (A) was calculated and analyze d. Also measurements were made between certain chosen landmarks on both the sides and analyzed. Results: The values for the right side were 8.12 ± 0.99 mm, 6.31 ± 0.64mm and 40.61 ± 7.79 mm2 and for the left side the values were 8.15 ± 1.00 mm, 6.19 ± 0.80 mm and 40.032 ± 8.10 mm2 respectively, for the mean length, width and area of the AECC. Also, the shape of AECC was typically round in most of the skulls studied (51.83%). Conclusion: By analyzing the length, width and area of AECC on both the sides, there was no statistical difference and the values were comparable with the studies done in the past.
