Forty cases with tongue-, or floor of the mouth-, or mandibular gingival carcinoma for which bilateral neck dissection was simultaneously performed, were retrospectively examined including T stage and histopathological grade of the primary lesion and clinicopathological features of the metastatic lesion. Both ipsilateral- and contralateral sides had pathologically positive nodes in 11 cases (pN (+) (+) ), only the ipsilateral side had the nodes in 14 cases ( pN (+) (-) ), only the contralateral side had the nodes in 2 cases (pN (-) (+) ), and both sides did not have nodes in 13 cases (pN (-) (-) ) . In most of the pN (+) (+) cases, the primary lesion belonged to T3 or T4 and showed high pathological malignancy grading and the number of metastatic lesions in the ipsilateral side was more than 3 and the metastatic lesions were located in level III or IV and extracapsular spread.
