[Applying combination of ultrasound and CT to diagnose paralaryngeal space tumor].

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.


CONCLUSION
The combination of ultrasound diagaosis and CT scan is of satisfactory clinical value in diagnosis of parapharyngeal space tumor.
