Neck dissection in squamous cell carcinoma of the tongue

SummaryAimThe purpose of this study was to assess the prognosis of patients with tonsillar squamous cell carcinoma with different stages of lymph node involvement and to determine the best elective neck dissection for those cases.Study designCase series.Material and Method51 patients with tonsillar tumors were treated between 1992 and 2001. The incidence of different tumor-node-metastasis stages was evaluated according to primary tumor extension.ResultscN0 patients had metastases in stages I and II only. Among pN+ subjects with stage I metastases, 6/7 had primary tumor extending to oral cavity.ConclusionSupraomohyoid neck dissection (stages I, II and III) is the elective treatment of choice when tonsillar primary tumor extends to oral cavity. When primary tumors are limited to the oropharynx, selective neck dissection of stages II and III proved to be more adequate
