Transoral robotic surgery for neurogenic tumors of the prestyloid parapharyngeal space

Abstract

The parapharyngeal space is a difficult area for a surgical approach due to anatomical complexity. We performed a minimally invasive and precise surgical technique to remove neurogenic tumors of the prestyloid parapharyngeal space using transoral robotic instrumentation. The mass was successfully removed in the two cases with three-dimensional visualization providing an excellent view of the resection margin and the dissection plane preserving the vital structures. An adequate resection margin was acquired, and no violation of the tumor capsule occurred. No significant complications were noted. Transoral robotic surgery was feasible for neurogenic tumors of the prestyloid parapharyngeal space, providing a sufficient resection margin and delicate dissection through excellent surgical views and instrumentation.
