Results
The 22 necks with suspicious lymph nodes,
were submitted a surgery,
where 712 lymph nodes were histological analyzed and 114 were malignant lymph nodes,
confirmed by surgery.
Levels malignant cervical lymph nodes had this distribution: 12 lymph nodes on level II (10.6%),
13 lymph nodes on level III (11.5%),
51 lymph nodes on level IV (44.7%),
8 lymph nodes on level V (7.1%),
27 lymph nodes on level VI (24%),
3 lymph nodes on level VII (2.6%).
