Assessment and treatment of neurogenic and non-neurogenic tumors of the parapharyngeal space.

The clinical and pathologic findings in eleven cases of parapharyngeal space tumors are described. The anatomy of this area and diagnostic procedures are discussed. Investigations should include a few basic examinations such as sialogram-computed tomographic (CT) scan, carotid angiogram, and echography. Several surgical approaches are considered in relation to the site and the size of the neoplasm. Prognosis depends on the histologic type of the tumor.
