Revisiting vascular contraindications for transoral robotic surgery for oropharyngeal cancer

OBJECTIVE: We analyzed the outcomes for patients with a retropharyngeal internal carotid artery (ICA) who underwent a transoral robotic surgery (TORS) procedure involving a cervical‐transoral robotic oropharyngectomy course with free flap reconstruction. METHODS: Patients were included in the prospective multicentric trial NCT02517125. These patients were scheduled to undergo surgery for an oropharyngeal localization. By pre‐operative CT scan and MRI it was determined that they had a retropharyngeal internal carotid artery. RESULTS: Three patients had a retropharyngeal ICA: a patient with a 35 mm synovial sarcoma of the tonsillar fossa, a patient with a T2N2b squamous‐cell carcinoma (SCC) of the glossotonsillar sulcus, and a patient with a T3N0 SCC of the tonsillar fossa in a previously irradiated field. These patients encountered neither preoperative nor postoperative complications. CONCLUSIONS: In our experience, TORS for oropharyngeal cancers appears to be feasible in patients with a retropharyngeal ICA, provided that the procedure has been adapted for complex situations.
