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

approach.

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

exposure.
