title: Supraomohyoid neck dissection with frozen section biopsy as a staging procedure in the clinically node-negative neck in carcinoma of the oral cavity.
abstract: A retrospective analysis was performed to evaluate the efficacy of elective supraomohyoid neck dissection in 57 newly diagnosed patients with squamous cell carcinoma of the oral cavity. The protocol included sampling of both the most suspicious and the largest node in the jugulodigastric region (if present) and the most distal jugulo-omohyoid lymph node (if present) for frozen section examination. In 10 cases, frozen section biopsy revealed metastatic disease, and surgery was continued using standard or modified radical neck dissection en bloc with the primary tumor. In another 10 cases, histologic examination of the supraomohyoid neck dissection specimens revealed occult nodal disease at other sites. In the histologically proven absence of metastatic disease in the supraomohyoid neck dissection specimens, disease recurrence in the neck occurred in only three cases (7%), all in the presence of local failure. The results of our analysis support the conclusion that elective supraomohyoid neck dissection with frozen section biopsy appears to be a valid staging procedure and a valuable approach to the management of the clinically node-negative neck in squamous cell carcinoma of the oral cavity.
