A case of hypopharyngeal venous malformation excised by transoral videoendoscopic surgery

Abstract

We herein report a case of hypopharyngeal vascular malformation in which the tumor was able to be completely removed by endoscopic transoral videolaryngoscopic surgery (TOVS). The patient, a woman in her 80s, had undergone KTP laser ablation under laryngeal microscopic surgery in year X-12 with a diagnosis of hypopharyngeal vascular malformation. In year X, TOVS using an FK-WO retractor and a curved endoscope was performed, and the mass was completely removed. The pathological diagnosis was venous malformation. One year after surgery, the patient had no dysphagia and no recurrence of the mass. Various laser ablation and sclerotherapy procedures have been reported for vascular malformations of the pharynx; however, they did not aim at total removal. The advent of new devices is greatly advancing the treatment of pharyngeal vascular malformations.
