Application of a facial injury severity scale in craniomaxillofacial trauma.
To establish a Facial Injury Severity Scale (FISS) that correlates with patient outcome and provides a practical tool for communication between clinicians and healthcare personnel for management of facial trauma. ⋯ We introduce a FISS that is easily calculated and reliably predicts the severity of maxillofacial injuries as measured by the operating room charges required to treat the facial injury. The scale is also an indicator of hospital length of stay. We anticipate this to be a valuable tool for assessment and management of maxillofacial trauma.

The influence of computed tomography motion artifacts on computer-assisted surgery.
Motion artifacts can significantly deteriorate the precision of a computer-assisted surgical intervention because they destroy the isometric representation of tomographic pictures. In the context of a study, the influence of typical motion artifacts on the precision of markerless laser registration in image-guided oral and maxillofacial surgery was analyzed, and quality factors for evaluation of the isometry of a computed tomography (CT) dataset were determined. ⋯ The isometry of a CT dataset should always be checked before performance of a computer assisted surgical intervention because anisometric datasets result in inaccurate patient registration and navigation.
