We examined 8 cases after costal cartilage autograft in clinical observation through optics microscope, verified that the framework keeps the nature of costal cartilage and pointed out the importance of prevention of infection. Ear reconstruction can be completed in preschool age because we observed that the reconstructed ear in preschool age could grow with the normal ear in pace (7 cases). With perichondrium costal cartilage autograft could live and grow better.
