Preoperative Imaging for Facial Transplant: A Guide for Radiologists

Published Online:https://doi.org/10.1148/rg.2019180167

In patients undergoing facial transplant, a stepwise approach to preoperative CT, CT angiography, digital subtraction angiography, and CT venography facilitates multidisciplinary team planning.

Facial transplant (FT) is a viable option for patients with severe craniomaxillofacial deformities. Transplant imaging requires coordination between radiologists and surgeons and an understanding of the merits and limitations of imaging modalities. Digital subtraction angiography and CT angiography are critical to mapping vascular anatomy, while volume-rendered CT allows evaluation of osseous defects and landmarks used for surgical cutting guides. This article highlights the components of successful FT imaging at two institutions and in two index cases. A deliberate stepwise approach to performance and interpretation of preoperative FT imaging, which consists of the modalities and protocols described here, is essential to seamless integration of the multidisciplinary FT team.
