ABSTRACT: Background. Parapharyngeal space (PPS) tumors are rare
tumors for which the surgical management differs widely. The purpose
of this study was to discuss the advantages and disadvantages of the
endoscope-assisted transoral approach over the traditional approaches.
Methods. This prospective study included 4 patients who were diagnosed
with PPS tumors and treated with the endoscope-assisted transoral
Results. The endoscope-assisted transoral approach described here safely
allowed for the resection of benign neoplasms with high surgical view to
the parapharyngeal neurovascular structures. The average tumor size was
42 mm. Three patients had isolated PPS tumors, and 1 patient had a tumor
originating from the deep lobe of the parotid gland. The postoperative histopathological
diagnosis of the patients was pleomorphic adenoma for 3 of
the patients, and marginal zone and follicular hyperplasia for the other.
Conclusion. This technique provided less operative trauma, a more comfortable
postoperative period, and, most importantly, increased operative
