PurposeCompare dose distributions of traditional versus conformal beam orientations in paranasal sinus malignancies.Materials And MethodsMaximum normal tissue doses, dose volume histograms (DVH), normal tissue complication probabilities (NTCP), and the percentage of each normal tissue receiving >80% of the average target dose (V80) were calculated.Results/ConclusionsConformal planning reduced the V80 to the optic nerves and chiasm as well as the normal tissue maximum doses to the ipsilateral and contralateral optic nerves and chiasm, and mean NTCPs.
