[Fabrication and application of three-dimensional autogenous cartilage framework in auricular reconstruction].

OBJECTIVE

To explore the fabrication and application of three-dimensional autogenous cartilage framework in auricular reconstruction.

METHODS

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 parts:the 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.

RESULTS

From January 1992 to December 2006, 5,248 patients of microtia were treated with 6,252 autogenous cartilage frameworks.

CONCLUSIONS

The three-dimensional framework is easily manipulated. The reconstructed ears look natural and had an erect contour. This method can effectively use the cartilage.
