Background: The growth of rib cartilages closely related to age determines the feasibility and results in auricular reconstruction.A prospective study would involve elective radiation that is not otherwise clinically indicated.Direct firm data such as rib cartilage growth preoperation is required.The aim of this study is to evaluate a method for rib cartilage assessment with reduced radiation dose.Methods: A total of 43 children with microtia in age from 5 to 7 years were included with Low-dose in coronary scan technique,17 childen selected randomly in age from 6 to 7 years were examined with routine axial scan manner as a control.Differences in terms of image quality and the radiation dose of the two groups were compared.
