Purpose: The current study sought to provide anthropometric data on normal auricles in a Han-Chinese sample using a 3D CT reconstruction technique.Methods: We studied the CT data of 485 adult Han-Chinese people(244 males and 241 females).To examine the relationship between auricle dimensions and age,the data were divided into three age subgroups.All measuring points were determined using 3D reconstructed images.Sixteen anthropometric 'landmarks' on the auricles were used to record twelve dimensional measurements.
