Salvage surgery can be performed with acceptable rates of postoperative complications. The clinical stage of the recurrent tumor and the previous site treated were the 2 major factors associated with the occurrence of postoperative complications.

Pathological lymph nodes in oropharyngeal squamous cell carcinoma are more frequent at level I than at level IV. This finding suggests that elective neck dissection for patients with oropharyngeal carcinoma should be a supraomohyoid neck dissection (levels I, II, and III) rather than a lateral neck dissection (levels II, III, and IV).

This study confirms the poor prognosis of patients with N3 neck disease, mainly when treated by radiotherapy alone. A radical neck dissection associated with adjuvant radiotherapy is indicated whenever feasible. Because of the high rate of distant metastasis, protocols including adjuvant chemotherapy should be investigated.
