Patterns of cervical node positivity, regional failure rates, and fistula rates for HPV+ oropharyngeal squamous cell carcinoma treated with transoral robotic surgery (TORS)

Our data suggests, in TORS for HPV+ OPSCC, neck dissection of levels II-IV accurately stages the neck pathologically and prevents regional recurrences, with adjuvant therapy when indicated, and survival outcomes are excellent. Single-staged operations did not result in any postoperative PCF. Avoiding dissection of level Ib with TORS oropharyngectomy limits morbidity to the marginal mandibular nerve and salivary function, and resulted in no postoperative fistulas with minimal reconstruction interventions.
