[Three-dimensional visualization for preoperative planning and evaluation in head and neck surgery]. / Dreidimensionale Bildprozessierung in der HNO-Onkologie zur präoperativen Planung und Evaluierung.

There are a lot of diagnostic possibilities for the preoperative planning in head and neck surgery. So far, no study was performed to evaluate if there is an advantage of three-dimensional visualization compared to conventional computed tomography yet. Additionally, there are no specifications for such a visualization prior surgery in head and neck surgery. This work describes different possibilities for segmentation and three-dimensional visualization for preoperative planning in head and neck surgery and tumor volumetry compared to conventional computed tomography. We describe new techniques and specifications for three-dimensional visualization.
