Transoral robotic resection of advanced recurrent nasopharyngeal carcinoma involving the internal carotid artery

Abstract

BACKGROUND: Transoral robotic surgery (TORS) is a reliable, minimally invasive approach for treating recurrent nasopharyngeal carcinoma (rNPC). However, tumours involving the internal carotid artery (ICA) are considered to be unsuitable for TORS. This paper presents the first case of transoral robotic resection of advanced rNPC involving the ICA. MATERIALS AND METHODS: This case is a 55 year-old male patient who received radiotherapy 27 years ago. This patient underwent a standard TORS resection 2 weeks after ipsilateral ICA embolization. RESULTS: Postoperative Magnetic resonance imaging and biopsy results indicated total resection. During the 2 month follow-up, no severe complications were found, and the primary site was tumour-free. CONCLUSION: This study preliminarily presents the feasibility and efficiency of advanced rNPC resection with TORS. TORS can potentially provide better quality of life for patients as a less invasive approach than current endoscopic surgery. Even so, the surgical approach should be selected strictly according to the tumour's location.
