title: [CT exam and 2D and 3D reconstructions in facial tumors diagnosis].
abstract: This study presents the CT imaging of a group of maxillofacial tumors that include benign tumors and primary and secondary malignant processes.
  
  
  METHODS
  All patients were CT explored with and without intravenous contrast, using specific head and neck protocols.
  
  
  RESULTS
  We studied the topography of the tumors, their impact on neighborhood regions and post-treatment results. The diagnostic of all patients had histological confirmation. In maxillofacial tumors and tumor-like diseases, 3D imaging was significantly superior to 2D axial imaging in showing the tumor shape and spatial relationships between tumors and surrounding structures. Two dimensional imaging and MPR imaging were excellent to reveal internal structure and pathological changes of tumors. 2D imaging and MPR imaging also achieved better results in showing tumors extended to soft tissues.
