RESUMEN
<p><b>OBJECTIVE</b>The key feature of Treacher-Collin's syndrome is malar dysostosis. The article focused on malar reconstruction for Treacher-Collin's syndrome and compared the implant materials.</p><p><b>METHODS</b>From 1994 to 2002, a total of 55 patients with Treacher-Collin's syndrome were treated with malar reconstruction. In the operation, the lateral orbital rim and the mala were exposed by the bicoronal incision or the subciliary incision. The mala was augmented and reconstructed with implants of different materials, including autologous bone (rib, ilia or cranium). Medpor biomaterial or bone cement.</p><p><b>RESULTS</b>The operations of the 55 patients were all successful without infection. The satisfactory rate in facial contour was 90%. Implant exclusion occurred in 2 cases using hone cement.</p><p><b>CONCLUSION</b>Malar reconstruction is the most important treatment for Treacher-Collin's syndrome. Every implant material has advantages and shortcomings. Autologous hone is the best material for malar reconstruction. Medpor is the best artificial material, with good histocompatibility, without exclusion, absorption and donor injury.</p>
