title: [Applying combination of ultrasound and CT to diagnose paralaryngeal space tumor].
abstract: OBJECTIVE
  To explore an effective way to diagnose parapharyngeal space tumor.
  
  
  METHODS
  The clinical data of 25 cases of this type of tumor, diagnosed by combinating ultrasound examination and CT scan, were analysed.
  
  
  RESULTS
  The diagnosis correspondence rate by the combinating way of ultrasound and CT is 92%. The combination of the two methods is likely able to reveal the overall shape, extend and feature of tumor, and to assist us in decision of the entrance of operation.
