Abstract: Objective According to the difference physiological characteristics of mastoid tissue in patients with auricle defect,different auricle reconstruction methods were used to complete ear reconstruction,and to explore the feasibility of individualized auricle reconstruction.Methods From June 2012 to October 2016,according to the different physiological characteristics of mastoid tissue,6 cases of auricle reconstruction were performed by retroauricular skin expansion,1 case by retroauricular fasciocutaneous flap expansion,and 4 cases by Nagata II method.Autogenous costal cartilage was used as ear scaffold in all patients.No complications such as chest deformity,exposure and infection of ear scaffold cartilage were observed.Results The follow-up period ranged from 10 months to 2 years,with an average of 15 months.11 patients and their families were satisfied with the shape of the reconstructed auricle.Conclusion According to the difference of physiological characteristics of mastoid tissue,individualized selection of different surgical methods is conducive to the ideal effect of ear reconstruction.
