Abstract: The decision to include level IIb lymph node dissection during surgical management of oral squamous cell carcinoma (OSCC) remains a topic of nuanced debate, especially considering the anatomical challenges and potential complications. This prospective observational study, involving 45 patients with operable OSCC, set out to assess whether routine dissection of level IIb lymph nodes is justified. Interestingly, only 6.6% of the cases showed metastatic involvement in this region, a figure closely aligned with previous literature. Most of these positive cases were associated with tongue carcinomas in advanced stages (T3), highlighting the unique lymphatic pathways of the tongue. It is evident that level IIb involvement often accompanies level IIa metastasis, yet no consistent correlation was observed in this study. This raises another point: should every patient undergo this technically demanding dissection when the yield is so low? The findings suggest a more selective approach may be warranted particularly omitting level IIb dissection when level IIa nodes are uninvolved?thereby reducing surgical trauma, especially to the spinal accessory nerve. Ultimately, this research advocates for tailored surgical strategies that prioritize oncological safety without compromising functional outcomes.
