Computer-assisted techniques in the surgery of the facial skeleton including the skull base are depicted for the very first time in this atlas of navigational surgery. New methods of non-invasive referencing and the use of virtual models in the field of oral and cranio-maxillofacial surgery are demonstrated. Clinical cases illustrate the practical use of this new technique. Experienced surgeons as well as trainees will benefit from the detailed and well-illustrated information on the use of computer technology in clinical routine, accompanied by the experimental basis of intraoperative accuracy. The authors' inventions in the field of non-invasive registration have led to widespread use of computer-assisted simulation and navigational surgery in this field, so the time is right for a comprehensive publication on the topic.
