[Sentinel lymphoscintigraphy in oral carcinoma: a clinical report of 10 cases].
OBJECTIVE; To determine the clinical value of preoperative in vivo location of sentinel lymph node (SLN) by lymphoscintigraphy (LS) in oral carcinoma.


METHODS
10 patients with oral carcinoma were included in this study (7 male to 3 female). 99mTc-dextron was injected peritumorally 24 h before surgery. Lymphoscintigraphy images were obtained in anterior and lateral views. SLNs were detected and removed with the aid of dye during surgery. A standard radical neck dissection was then performed, and all lymph nodes were analyzed by HE staining.


RESULTS
SLNs were successfully detected in 10 regions of 8 patients via lymphoscintigraphy. Consistent with the result of LS, 15 blue-stained SLNs were identified by means of dye method in 8 of 10 regions which the LS images indicated.


CONCLUSIONS
This study suggests that preoperative in vivo location of SLN via lymphoscintigraphy should be helpful for the application of SLNB in oral carcinoma.
