The necessary extent of cervical dissection in oral squamous cell carcinoma (OSCC) is still under discussion. Due to its anatomical properties Robins level IIb has a special role in neck dissection. This study focuses on the lymph node metastatic behaviour of OSCC in level IIb and evaluates its worth of dissection. 183 consecutive patients with OSCC were retrospectively screened for age, gender, TNM classification, cancer stage (after UICC), tumour localization, tumour infiltrations depth, and affected cervical lymph node levels. Associations between lymph node metastases and the above-mentioned characteristics were evaluated using Pearson's chi square test and Spearman's rho correlation analyses. Metastases in level IIb were seen in only 3.3% of all patients, and none of these metastases were an exclusive metastasis. Lymph node metastases most likely occurred in levels I and IIa at ipsilateral sites, and metastases were significantly related to tumour size (p?
