Abstract：
There is debate if the lymphatic drainage pattern of oral maxillary cancer is to the retropharyngeal lymph nodes or to the cervical lymph nodes. Insight in drainage patterns is important for the indication for neck treatment. The purpose of this study was to identify the lymphatic drainage pattern of oral maxillary cancer via preoperative lymphoscintigraphy.
Eleven consecutive patients with oral maxillary cancer treated in our center between December 1, 2012, and April 22, 2016 were studied. Sentinel lymph nodes identified by preoperative lymphoscintigraphy after injection of 99m Tc-nanocolloid and by intraoperative detection using a γ-probe, were surgically removed and histopathologically examined.
In 10 patients, sentinel lymph nodes were detected and harvested at cervical levels I, II, or III in the neck. In 2 patients, a parapharyngeal sentinel lymph node was detected. One of the harvested sentinel lymph nodes (1/19) was tumor positive.
This study suggests the likelihood of 73% of exclusively cervical level I to III sentinel lymph nodes in oral maxillary cancer. © 2016 Wiley Periodicals, Inc. Head Neck 39: 486-491, 2017.
