Ten-year experience in microtia reconstruction using tissue expander and autogenous cartilage.
OBJECTIVE
Ear reconstruction is a complex multi-staged procedure in otology. A variety of surgical strategies have been devised for the reconstruction. In this paper, we present our 10-year experience in microtia reconstruction using tissue expander and autogenous cartilage in microtia reconstruction.


METHODS
The process of our method is divided into three stages. In the first stage, the kidney-shape tissue expander was implanted subcutaneously. With 1 month of inflation, the tissue expander offered the non-hairbearing and well-vascularized skin. In the second stage, we improved the technique of cartilage fabrication and used an expanded two-flap envelope to erect framework. In the third stage, the tragus and concha were reconstructed.


RESULTS
3332 patients have undergone ear reconstruction using tissue expander and autogenous cartilage from 1996 to 2006. The follow-up study showed the satisfactory contour of the reconstructed ears.


CONCLUSIONS
Techniques using tissue expander and autogenous cartilage in microtia reconstruction was easily done and the complications were rare.
