[Parapharyngeal space neoplasms].
OBJECTIVE
To explore the diagnose and management of parapharyngeal space (PPS) neoplasms.


METHODS
Records of 48 patients with PPS neoplasms operated from 1988 to 1998 were reviewed.


RESULTS
Neurogenic tumors were the most common neoplasma in primary PPS neoplasms. CT and MRI could provide clinically informations such as their size, shape, extent and site. Tumor vessels could be clearly seen by carotid arteriography. The majority of PPS tumors were resected by a transcervical approach.


CONCLUSIONS
CT and/or MRI are essential for diagnose and presurgical planning, Arteriography can be used only when CT or MRi suggest a glomous tumor, or possible involvement of carotid artery, or when those tumors put the carotid artery at a risk for surgical injury. Transoral approach may be used for small tumors and transparotid approach may be especially indicated for removing deep lobe parotid tumors with extention to the PPS. When there is a significant risk for injury the internal carotid artery radiological evidence are necessary for infratemporal approach.
