Application of rotation skin flap in the repair of auricle injuries

Objective To investigate the techniques to repair partial or total auricle avulsions at the middle-upper part.Methods In the repair of ten partially injured auricles,the skin at the side of the injury connected with the normal was reserved as much as possible and sutured directly,while the skin at the opposite side of injured auricle was removed,and the skin defect was repaired with adjacent skin flap. One auricle was bitten off and lost. For such a U shape defect,the skin at both sides of the remnant auricle was removed and repaired with a flap formed by the skins from crus of helix to tragus combined with the tragic cartilage. Results The patients were followed up from six months to eight years.All the auricles recovered well with good shapes and without obvious deformities. Conclusions To the partial or total auricle avulsions injured at the middle-upper part,the skin at the side of the injury connected with the normal can be sutured directly. The skin at the opposite side of the injury,the skin defect can be repaired with adjacent skin flap. If the defect of the auricle at the middle-upper part is a little smaller than tragic cartilage,it can be repaired with pre-auricular composite tissue flap and post-auricular rotation skin flap.
