Preserving Level IIb Lymph Nodes in Elective Supraomohyoid Neck Dissection for Oral Cavity Squamous Cell Carcinoma

Abstract

Level IIb lymph node metastasis was rare in this study, and nodal recurrence in this area after SOHND in squamous cell carcinoma of the oral cavity was infrequent. Therefore, this region may be preserved in elective SOHND in patients with squamous cell carcinoma of the oral cavity.
