Imaging of the midfacial and orbital trauma.

Abstract

The severity of midfacial and orbital injuries depends on the one hand on cause, force vector, load point, or area and on the other hand on the bony and soft tissue resistance as well as individual anatomy. These variables result in a variety of possible injuries of the midfacial and orbital complex. The time critical choice of an adequate imaging modality of these injuries is influenced by the possible severity of concomitant injuries. Besides the confirmation of a clinical diagnosis, the need for high-resolution three-dimensional imaging for preoperative planning of facial reconstruction using intraoperative navigation has become more and more important in the past years. To achieve optimal functional and esthetic outcomes, the anatomical complexity of the midface has to be addressed and the adequate imaging modality has to be chosen keeping the upcoming surgical treatment in mind. The current imaging modalities for midfacial and orbital trauma are presented and critically evaluated depending on the indications. Furthermore, new strategies to support surgeons in achieving best possible midfacial reconstructions are discussed. An algorithm to choose the adequate imaging modality in midfacial and orbital traumatology is provided.
