Regarding the incidence of the various types of the anthelix described by Maruyama. in the males types 1.2 and 3 are 60.24%,13.99% and 25.77%, respectively. In the females types 1.2 and 3 are 58.43%. 12.02% and 29.56%. respectively. No differences exist in both sexes and in the various age groups. 6). Sesamoid cartilages appeared in 14.32% of the males and in 8.04% of the females. No differences are noticeable in both sexes and in the various age groups.
