**1. Introduction**

Craniomaxillofacial reconstruction poses inherent and unique challenges due to the threedimensional configuration of the proposed construct and the critical importance to restore speech, swallowing, mastication and symmetrical facial contour. Additionally, reconstruction results are often inconsistent and learning curve dependent.[1-43] Until recently, the overall success in bony reconstruction of the craniomaxillofacial skeleton has relied mainly on the use of surgical trial-and-error and 2D imaging modalities. Virtual surgical planning (VSP) and computer aided design (CAD) / computer aided modeling (CAM) is an exciting new technol‐ ogy that presents advantages in complex craniomaxillofacial reconstruction, with potential to transform the approach and execution of challenging head and neck reconstructions.[30] Among the reported benefits of VSP- CAD/CAM are increased reconstructive accuracy, reduced OR and graft ischemia time, improved patient satisfaction and ease of use.[1, 9, 19] VSP- CAD/CAM is gaining traction in craniomaxillofacial reconstruction applications and offers opportunity for increased accuracy, improved efficiency, enhanced outcomes and ease of use.[34, 43] To illustrate this point, the usage of this technology in different applications is presented in subsequent sections with an emphasis and case study example for an oncologic indication.
