Management of parapharyngeal space cavernous sinus haemangioma using transoral robotic surgery

Abstract

Cavernous haemangiomas are a very rare occurrence in the parapharyngeal space (PPS). Here, we present a case of a 58-year-old woman with an incidentally identified left PPS mass thought to be a pleomorphic adenoma that underwent excision by transoral robotic surgery (TORS). Intraoperative findings demonstrated no solid mass present and histological assessment of resected tissue confirmed a cavernous haemangioma. We discuss our experience in the management of a radiological and surgical mismatch of a PPS mass in what we believe to be the first cavernous haemangioma to be excised by TORS in this region.

Keywords: Cavernous haemangioma; Parapharyngeal space; Transoral robotic surgery; Venous malformation.
