Abstract

Tumors of the parapharyngeal space (PPS) are rare, most originate from salivary and neurogenic tissues, and most are benign. However, there are some rarer masses in the PPS, with just a few published reports in the literature worldwide, and we may not consider them in the differential diagnosis of PPS neoplasms. We report three cases of rare masses in the PPS: Warthin's tumor, branchial cleft cyst, and carcinoma ex pleomorphic adenoma. The three patients were admitted to our department with complaints of painless swelling in the lower side of the right face or a long history of snoring; diagnoses were confirmed histopathologically. An endoscopy-assisted transoral approach was used that allowed wide visibility for safe resection and resulted in a short hospitalization time and good functional and cosmetic outcomes. All patients have been followed to the current time, and there have been no recurrences. The transoral endoscopy-assisted approach appears to be safe, effective, and less invasive for excision of masses in the PPS.
