Description

We clinically examined 29 patients with squamous cell carcinoma of tongue, floor of the mouth, and maxillary gingiva who received unilateral functional neck dissection with preservation of the sternocleidmastoid muscle, internal jugular vein, and/or accessory nerve.<BR>The 5-year cumulative survival rate of all patients was 80.4%, that of 19 pN (+) patients was 68.6%, and that of 10 pN (-) patients was 100%. Pathologically, 4 metastatic lymph nodes (LNs) were found in 1 patient, 3 LNs in 3 patients, 2 LNs in 6 patients, and 1 LN in 9 patients. LNs were located in level 1 in 5 paitents, level 2 in 12, and level 4 in 2. Extranodular metastatic lesions were found in level 1 in 1 patient and in level 2 in 4. Among the patients with a poor prognosis, 2 LNs were found in 2 patients, 3 LNs in 1, and 4 LNs in 1, extranodular lesions were found in 2 patients, and LNs were located in level 2 in all patients.<BR>Our results suggest that functional neck dissection is indicated for patients who have single and movable nodular metastatic lymph node.
