Fabrication and application of three-dimensional autogenous cartilage framework in auricular reconstruction / 中华整形外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the fabrication and application of three-dimensional autogenous cartilage framework in auricular reconstruction.</p><p><b>METHODS</b>The process of fabrication of three-dimensional cartilage framework consisted of cartilage harvesting, carving and assembling the cartilage. The rib cartilage was harvested separately. The three-dimensional framework was composed of three main partsthe helix, the base and the pad, at different layer. The framework was fabricated according to the development of rib cartilage and contour and height of the reconstructed ear.</p><p><b>RESULTS</b>From January 1992 to December 2006, 5,248 patients of microtia were treated with 6,252 autogenous cartilage frameworks.</p><p><b>CONCLUSIONS</b>The three-dimensional framework is easily manipulated. The reconstructed ears look natural and had an erect contour. This method can effectively use the cartilage.</p>
