Mean dose and probability of complications for the parotids. Mean dose, Dmean (above) and probability of complications, PI (below) in the ipsilateral and contralateral parotid for each of the seven studied cases. Horizontal colour lines show average values for all patients. The dashed lines in the upper plots indicate the dose objective of 26 Gy generally used as the tolerance dose level in the parotids [25]. Dose values refer to biologically corrected dose to a fractionation of 2 Gy per fraction. Nasop. stands for nasopharynx, Orop. for oropharynx, Hipop. for hipopharynx and Tong. for base of the tongue.
