[Three kinds of standing-materials for concha in reconstruction of ear]

In the reconstruction of the concha, standing support was necessary. From 1984 to 1996, 33 cases of aurical defects were admitted. Three standing-materials were chosen, and they included carved autogenous cartilage, heterogenous concha cartilage and steel wire work silicon-wires with silastic rubber tube. After expansion of the postauricular skin by tinsion expander, the standing-material was enveloped and total ear reconstruction or repair was performed. After followed up for average of 3.5 years, of the twenty-two cases, 16 had a satisfactory result, unsatisfied in 3 and failure in 3. It was concluded that the outcome of autogenous concha cartilage as a standing-material was good. The other two materials if used should be very carefully.
