Combined transnasal endoscopic and transoral robotic resection of recurrent nasopharyngeal carcinoma

Abstract

Background: We report a case of resecting a recurrent nasopharyngeal carcinoma using a combined technique of transoral robotic surgery and transnasal endoscopic surgery.

Method: A small recurrent tumor was located in the roof of the nasopharynx. The inferior part of the resection was performed with a da Vinci surgical robot transorally after splitting the soft palate to expose the nasopharynx. The superior part of the resection, including removal of the anterior wall and floor of the sphenoid was performed transnasally under endoscopic vision.

Results: The tumor was removed enbloc with the sphenoid sinus wall with clear resection margin. Recovery was uneventful and the patient had minimal morbidity from the operation.

Conclusion: For minimally invasive surgery to resect recurrent nasopharyngeal carcinoma, transnasal endoscopic surgery and transoral robotic surgery compliments each other, allowing improved resection.
