Use of a titanium cutting guide to assist with raising and inset of a DCIA free flap

Abstract

Reconstructing maxillary defects can be challenging. In particular, Class 3 and 4 defects require careful planning. Bone for reconstruction must be placed in the correct three dimensional (3D) position in order to achieve a good cosmetic and functional result. Correct size and positioning of the harvested bone also enables placement of dental implants and allows rehabilitation. We describe the use of a Deep Circumflex Iliac Artery Flap (DCIA) cutting guide to aid safe harvest and positioning of the correct quality and quantity of bone. We illustrate the benefits of using a guide based upon stereolithographic planning models of the pelvis by presenting 4 cases where planning to this level has been used. Our experiences clearly demonstrate the potential benefits that preformed cutting guides may have on outcomes when reconstructing complex maxillary defects. In particular, we note a reduction in operative time and improved functional and aesthetic results. The use of such a guide has not previously been described.
