[Individual treatment planning with computed tomography for extended ethmoidomaxillary tumors (author's transl)]

Individual computer-assisted treatment planning using CT was performed in 10 patients with advanced ethmoidomaxillary tumors. Immediate and good exploration of the pterygopalatine fossa and of the para- and retropharyngeal cavities can be accomplished by means of computed tomography. The target volume was defined more exactly with the help of computed tomography, and the choice of the optimal adjustment thus was possible.
