Abstract：Objective To explore the surgical repair methods of different types of upper auricle defects.Methods A total of 10 cases of upper auricle defects treated in Department of Plastic Surgery,Xijing Hospital,Air Force Medical University from January 2020 to December 2022 were retrospectively analyzed.According to the defects and local skin conditions of patients,two different repair methods were selected.The patients with only skin defects and a small amount of ear cartilage defects were treated with posterior auricular flap.For patients with severe defects involving multiple anatomical subunits of the auricle,skin soft tissue expansion and autologous costal cartilage were used for staged partial ear reconstruction.In the first stage,a skin soft tissue expander was inserted in the posterior ear area;in the second stage,autologous costal cartilage harvesting,expanded skin flap transferring and partial auricle reconstruction were performed;and in the third stage,the partial reconstructed auricle was trimmed and adjusted for a better appearance.Results There were 10 cases in this group,including 6 cases with posterior auricular flap and 4 cases with staged partial ear reconstruction.The follow-up period was 3 to 18 months.There were no complications such as hematoma formation,infection,flap necrosis and severe scar hyperplasia.The auricle shape was good and the patients were satisfied.Conclusion Selecting suitable repair methods according to the condition of upper auricle defects can obtain a good repair effect.
