ABSTRACT
Extended mandibular defects can be safely managed by applying microvascular free bone transfer. The flap of choice for this procedure is a fibula free flap due to its anatomical structure, proper length and good plasticity. The body of the mandible can be formed by removing wedge bone segments. However the gonial angle can be formed on a different, safer and easier way by performing axial osteotomy as it is done in the orthognathic surgery. The special advantage of this method is that by setting the exact angle of the ascending mandibular part, the ramus replacer fibula segment is perfectly suitable for the replacement of the head of the mandible. While recalling the anatomy of this region our clinical case demonstrates the functional reconstruction of these two delicate mandibular parts.
