Chin osteotomy is used in esthetic and functional procedure; genioplasty shows different surgical options as lineal osteotomy, curved osteotomy, segmental osteotomy and others for different conditions of the face. This communication shows the use of two surgical guides used in a patient with extremely facial asymmetry; the surgical plan was realized in a stereolithographic biomodel. The first surgical guide was used for osteotomy and the second surgical guide was used for putting the plate, previously bent, and for segmented osteotomy in the planned position on the biomodel; this technique showed adequate adaptation and security in this extremely asymmetric case. The potential use of this surgical guide was discussed.
颏成形术用于美容和功能性手术；颏部整形术针对不同面部情况展示了多种手术方式，如线性截骨术、弧形截骨术、节段性截骨术等。本文介绍了在一名面部极度不对称患者中使用两种手术导板的情况；手术方案在立体光刻生物模型上制定。第一个手术导板用于截骨，第二个手术导板用于放置预先弯曲的接骨板，并在生物模型上的预定位置进行节段性截骨；在这种极度不对称的病例中，该技术显示出了良好的适应性和安全性。文中还讨论了这种手术导板的潜在用途。
