A. Ferlito et al., Is extended selective supraomohyoid neck dissection indicated for treatment of oral cancer with clinically negative neck?, ACT OTO-LAR, 120(7), 2000, pp. 792-795
Oral cavity tumors may develop occult metastases to the cervical lymph node
s. Current imaging techniques and routine histopathologic methods may fail
to detect lymph node micrometastases, but the surgeon has to electively dis
sect a neck at risk of developing clinical disease. Supraomohyoid neck diss
ection has been the elective surgery for treating a clinically negative nec
k in patients with oral cavity primaries. A Literature review revealed that
level IV nodes can be significantly affected by occult disease with and wi
thout metastases in level I-III lymph nodes. This means that level IV nodes
have to he included in the supraomohyoid neck dissection, resulting in a m
ore extensive surgical procedure to ensure a margin of oncological safely.
