Abstract

Retropharyngeal schwannoma is rare. To the best of our knowledge, only 18 cases have been published in the English literature. Complete surgical excision is the treatment of choice for schwannomas. Transoral approaches have been applied for smaller lesions, and external cervical approaches are preferred for larger and more complex lesions. In this report, we present a case of large retropharyngeal schwannoma that was excised using an endoscopic-assisted transoral approach with palatal splitting. Postoperative functional and oncologic outcomes were satisfactory with no reported intraoperative/postoperative complications.

The asterisks point to the tongue, retracted by the retractor system. The posterior pharyngeal wall is bulging with intact mucosa. B. Posterior pharyngeal wall incision. The edge is grasped with Allis forceps. The tumor capsule is exposed. C, D. En bloc delivery of the mass. E. Palatal repair.
