Objective To investigate the feasibility and effect of using skin expansion combined with autologous rib cartilage framework repair post- traumatic auricle defects. Methods According to th size of auriclar defect,50- 80ml expander was implanted beneath retroauricular facia behand auricle. The second stage operation began when the expansion volume reached 70- 100ml,expander was removed and the opposite 7th,8th or 7th,8th and 9th rib cartilage were harvested,and ear framework was fabricated,we used skin flap to envelope rib cartilage and repair the defects,The operation of auricular framework joined reisdual auricle was performed after 3 months. Results Except 0.5cmí0.5cm skin necrosis accured in 1 patient,and healed through dressing,the wounds of all cases were healled normally without complications,The satisfactory auricule appearance were acquired. Conclusion Skin expansion combined with autologous rib cartilage framework repair post-traumatic auricle defects can aquire better affects.
