Abstract
PURPOSE: Transoral surgery for suspected or proven oropharyngeal malignancies has increased significantly with the practice of transoral laser microsurgery (TLM) and transoral robotic surgery (TORS). An accepted alternative technique is endoscopic video-assisted transoral (EVAT) surgery. Our aim is to review the clinical, oncological and functional outcomes of this technique at our institution.
METHODS: 56 consecutive patients undergoing EVAT surgery as part of their cancer work up or treatment were reviewed, focusing on clinical, oncological, and functional outcomes.
RESULTS: Patients had primary oropharyngeal cancer or carcinoma of unknown primary (CUP) staged between T0-T3 and N0-N3. EVAT surgery identified a primary in 47.1% of CUP with p16 positive disease. Major haemorrhage occurred in 1.8%, with eight post-operative complications. 8.9% of patients developed locoregional recurrence. Mean MD Anderson Dysphagia Inventory score was 76.4 following EVAT surgery, 68.8 after EVAT surgery + radiotherapy and 67.1 after EVAT surgery + chemoradiotherapy CONCLUSION: Early clinical, oncological and functional outcomes following EVAT surgery are comparable to TLM and TORS.
LEVEL OF EVIDENCE: 4 (case series).
