Comparison of three different techniques in parotid gland tumors using three dimensional conformal radiation therapy

Introduction: Background: Radiotherapy of parotid tumors is achieved by different radiotherapy techniques. So they deliver the dose to organs at risk such as contralateral parotid, temporal lobe & spinal cord. The consequences of high dose to OARs are xerostomia, Temporal lobe necrosis and loss of hearing. Purpose: The aim of this study was to compare different treatment tech...
