Objective:
To investigate the diagnostic value of CT and MRI in tumors of parapharyngeal space (PPS).
Method:
The data of one hundred and thirty-eight patients with PPS tumor treated in our department during the period from January, 1988 to January, 2005 were collected and reviewed. Eighty-three men and 55 women were enrolled, not including patients with metastasis tumors in PPS or nasopharyngeal carcinomas invading PPS. The age varies from 7 to 73 yrs(average 44.7 yrs). Among the patients, 12 were operated for the second time because of recurrence. All the patients were examined by CT or/and MRI.
Result:
CT and MRI could provide the position, size, confine of the tumor and its relationship with cervical blood vessels well, which were important to operation schemes.
Conclusion:
CT and MRI before operation are valuable to the treatment of PPS tumors.
