Objective: To investigate the therapeutic effect of retro-auricular expanded flap and cartilage graft for reconstruction of traumatic ear defect.
Methods: From Aug. 2008 to Aug. 2010, 10 cases of traumatic ear defects were treated with retro-auricular expanded flap and cartilage graft. The expanders (volume, 50 ml) were implanted subcutaneously at retro-auricular area on the first stage. Then the expansion began at 1 week after operation until the volume reached 60 ml. On the second stage, the ear defects were reconstructed with the expanded flaps, rib cartilage framework, as well as skin graft.
Results: All the wounds healed primarily without any complication. The patients were followed up for 6 months to 2 years with satisfactory cosmetic results. Good symmetry was achieved.
Conclusions: It is an effective and reliable method to reconstruct traumatic ear defect by retro-auricular expanded flap and cartilage graft.
