Abstract: The palmar dermatoglyphics were studied on 380 deafmutes (190 males and 190 females). The data were compared with those of normal group. The index of whorl of the fingers is higher in the deaf-mutes, while that of arch and radial loop of the fingers is lower than those of the normal gr?up. The occurrence frequency of normal type of palmar creases is lower than the normal group. The mean values of t-d TRC are 175.70±20.82 for deaf-mutes, which are significantly lower than those of normal group.
