摘要

Dissection of the Level IIb region in patients with OSCC may be required only in cases with advanced N stage, positive Level IIa lymph nodes, and extracapsular spread. Furthermore, in tongue cancers (high propensity of isolated Level II involvement), retromolar trigone, and floor of mouth cancers, routine Level IIb clearance should be considered.
