We studied the occurrence of deformation after collection of auricular cartilage. Subjects numbered 28 (15 with auricular cartilage collection and 12 without serving as a control group). We measured ear length, ear width, ear attachment length, auricular cartilage length, auricular lobe length, and auricle height, evaluating questionnaires given to subjects. Results showed that the collection of auricular cartilage does not result in deformation. In conclusion, the collection of auricular cartilage has few risks in view of cosmetics.
