RESUMEN
Objective@#To investigate the effect and safety of ultra-thin oblique posterosuperior auricular fascial flap in the second stage of ear reconstruction.@*Methods@#Fifty-six cases with congenital microtia treated in The Second Affiliated Hospital of Zhengzhou University Medical Cosmetology Department from November 2015 to November 2018 were selected as the research objects. In the first stage, the costal cartilage ear stent was implanted, and in the second stage. The ultra-thin posterior oblique fascia flap was used to cover the stent. And the cranioauricular angle was reconstructed by free skin grafting.@*Results@#48 cases of the 54 cases completely survived, and 8 cases had hemorrhage after operation. The wounds were healed after dressing change. The postoperative cranioauricular angle was close to the healthy side.@*Conclusions@#In the second stage of ear reconstruction, the retroauricular ultra-thin fascial flap method has reliable blood supply, small wound, unswollen reconstructed ears, and good outcome. It is a good choice for covering the ear framework.
