Abstract： Objective  To investigate the clinical efficacy of free transplantation for postauricular complex tissue to repair skin and soft tissue defects after facial melanocyte nevus resection. Methods  From 2015 to 2018， 32 cases with facial melanocyte nevus， 15 cases of nasal wing， 12 cases of upper lip， 5 cases of nasal dorsum， and the size of melanocyte nevus was 6-15mm. After the skin biopsy was completely removed， the postauricular complex tissue was resected according to the size and depth of the wound for free transplantation， and the postoperative appearance evaluation table on the scale of 1-10 for color， texture， cicatrix， and the satisfaction survey was conducted. Results  All the complex tissue flaps of 32 patients were survived. After 1 year follow-up， the color and texture of the flaps were close to the surrounding area， no cicatrix hyperplasia， and the evaluation was excellent. The patient satisfaction was 90%.  Conclusion  The free transplantation for postauricular complex tissue can be used to repair the wounds after the removal of melanocytes from the special facial parts. The operation is simple， safe and has high postoperative satisfaction. It’s worthy of popularizing.
