Transoral Videolaryngoscopic Surgery （TOVS） for the anterior wall oropharyngeal cancer and indication of the transcervical ligation of the cervical artery

Transoral videolaryngoscopic surgery (TOVS) is established as a minimally invasive transoral surgery. The neck lymph node for node-positive cases is dissected on the same day. For cases with deep invasion of the tonsil and tongue base tumor, bleeding from the dorsal lingual artery should be carefully managed. Herein, we report a case of p16 negative tongue base cancer (T1N2bM0) which was resected by TOVS and neck dissection with ligation of the lingual artery. We did not see any active bleeding during and after the opera-tion. The indication of cervical artery ligation for tonsil and tongue base cancer is discussed.
