Sumario:OBJECTIVE: Primary parapharyngeal space (PPS) tumors are one of the most challenging head and neck tumors to diagnose and treat. We analyzed our experience in patients with PPS tumors who were treated in our hospital over 13 years. METHODS: We retrospectively reviewed 16 patients with PPS tumors between 2006 and 2018. The study included clinical symptoms, histological types, surgical approaches, adjuvant therapies, postoperative complications, and prognosis. RESULTS: The mean age of the patients was 49.63 ± 17.03 years. A palpable neck mass (56.3%) was the most common symptom. In our series, 78.6% of the tumors were benign, and of these, schwannomas were the most common (6/14, 42.9%). Three surgical approaches were used in our patients, including transmandibular (57.1%), transcervical (21.4%) and transparotid (21.4%) approaches. Few complications were reported, including hoarseness and numbness. Adjuvant therapy was administered depending on pathological parameters of the tumors. No recurrence was observed during a mean follow-up of 60.6 months in patients with malignant tumors. CONCLUSIONS: Radiological studies of PPS tumors are essential for diagnosis and surgical planning. Excision of PPS tumors using appropriate surgical approaches provides good outcomes.
