“…Both CT and CBCT imaging are frequently applied for surgical planning as a guidance or "road map" (2,3,20) to avoid possible severe complications such as serious bleeding, blindness and injury of the central nervous system (7,21) during the intervention. To increase the success and safety of the surgical procedures, a more extensive use of theoretical modeling might be used for personalized treatments (22), aiding the operator performing the surgical action ahead of time. A good number of publications deal with the current state of the training methods (23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33) and to make the surgery procedure individually case-related, for instance, by using rapid prototyping (6,23,31) and virtual reality (7,27,28,32,33).…”
