Abstract : An anatomically correct mandibular reconstruction after ablative tumour surgery continues to be a challenge even after the advent of microsurgical bone transfer. Complex microvascular reconstruction of the large defects requires accurate preoperative planning. Otherwise, the inappropriate post-operative position of the reconstructed bone would produce gross aesthetic, functional and psychosocial deficits. The precise shaping and positioning of the graft is vital in recreating the aesthetic symmetry of the face. The positioning if the basal bone in the neutral zone is also essential for proper dental rehabilitation. The availability of 3D computer planning software allows for an improved and more predictable reconstruction outcome. We present a simple method where a pre-operative 3D CT reconstructed image was used for accurate planning of reconstruction of the horizontal and vertical mandibular ramus as well as the mandibular angle. This method has shown to lead to a predictable shape of the reconstructed neomandible. This is also a useful approach to plan the precise osteotomy sites and angulations.
