Abstract：Objective To explore the clinical effect and surgical method in the repair of auricle and external auditory canal skin defect.Methods From 2011 to 2016,29 cases of auricle and external auditory canal skin defect were involved in the study.Auricle skin defects were repaired with ramus auricularis arteriae auricularis posterioris pedicled flaps and external auditory canal skin defects were repaired with ramus occipitalis arteriae auricularis posterioris pedicled flaps.A summary of the operation methods and clinical results was made.Results All operations were completed successfully,and the average operative time was (62.1 ± 15.3) min.All flaps survived completely,and the operation incisions healed to class A standards.No necrosis,infection or other complications occurred.There was no significant difference of length or width of the injured ear compared with the uninjured side (P＞0.05) at one month postoperative.The temperature of the cavum conchae and the contour of the injured ear was lower than that of the healthy side on the first day postoperative,and the difference was statistically significant (P＜0.05).At 3 and 7 days postoperative,the temperature of the cavum conchae and the contour between the injured and the healthy ear showed no significant difference (P＞0.05).At 3 months after the operation,the subjective evaluation was satisfactory in 17 cases,moderately satisfactory in 8 cases,and generally satisfactory in 4 cases.The subjective satisfaction rate was 86.21％.The objective evaluation of the surgeon was satisfactory in 16 cases,moderately satisfactory in 10 cases,and generally satisfactory in 3 cases.The objective satisfaction rate was 89.67％.Conclusion Auricle skin defects repaired with ramus auricularis arteriae auricularis posterioris pedicled flaps and external auditory canal skin defects repaired with ramus occipitalis arteriae auricularis posterioris pedicled flaps can obtain a relatively high satisfaction rate among both surgeons and patients.
