The aim of this paper was to describe our surgical technique and retrospective review of the treatment of benign parapharyngeal tumors. We used a modified transcervical approach in twelve patients with large tumors. Pathological diagnose comprised 7 cases of pleomorphic adenoma, 4 cases of schwannoma, and 1 case of oncocytoma. The mean maximal tumor diameter was 4.8 cm (range: 2.0-9.0 cm) and the mean vertical distance from the skull base was 1.3 cm (range: 0-3.5 cm). The mean surgical time was 198 minutes (range: 104-369 minutes), and the mean blood loss was 82 ml (range: 25-200 ml). The average follow-up time was 37 months (range: 8-74 months) and there was no clinical or radiological signs of residual or recurrent tumor. The modified transcervical approach facilitates the removal of large tumors, but only in benign cases.
Key words :modified transcervical approach, benign parapharyngeal tumor, surgical technique
