Application of auricle radial cartilage incision in mild to moderate type of concha-type microtia patients
Objective To evaluate the auricle radial cartilage incision as for a method for the alternative to treat mild to moderate type of concha-type microtia.Methods As for an example of five patients aged between 6 to 35 and who were diagnosed with mild to moderate type of concha-type microtia,in a period between 2023 May to 2023 Dec.the Department of Plastic Surgery of The First Hospital of China Medical University applied auricle radial cartilage incision with autologous cartilage form auricle concha and skin graft for treat-ment.The auricle width,perimeter and the scores of detailed structures of the affected ear were recorded and evaluated preoperatively and postoperatively.The satisfaction and the complication of the operation were followed and recorded.Results The average improvement of the width and the perimeter of the affected ear is about 31 percent and 28 percent respectively,measured immediately after surgery.The average score of ear fine structure increased by about 35%.The width and the perimeter of the affected ear have been both improved and the improvements have been proved to have significant differences(P＜0.01).The scores of detailed structures of the affected ear has also been improved and the improvement has been proved to have difference(P＜0.05).Conclusion The auricle radial cartilage incision as-sisted with autologous cartilage form auricle concha and skin graft is a promising alternative to the method costal cartilage graft for the pur-pose of auricle reconstruction in mild to moderate type of concha-type microtia patients.
