Hair patterns of the pinna among the Central Indians.

The hair patterns of the pinna have been studied in a selected sample of 767 males and 5 females from Central India, all with hairy pinnae. The age of the males ranged from 21 to 85 years, and that of the females from 2.5 months to 32 years. All subjects were healthy and did not demonstrate any endocrine disturbance. The commonest hair pattern of the elevated areas of the pinna among the males was the helico-lobulo-antitragal, whereas in the females it was the helical. The hair pattern of the depressed areas of the pinna showing highest frequency was the conchal. The majority of the hairy pinnae are associated with bilateral tragal hair and the maximo-pilose distribution of the facial hair. The Central Indian males resemble the White males in their hair distribution of the pinna.
