We retrospectively investigated 28 patients with stage Ⅰ and Ⅱ squamous cell carcinoma of the tongue between 2003 and 2010, to examine whether depth of tumor invasion could be used to predict the potential for subsequent cervical lymph node metastasis by ultrasonography with intraoral scanner. Ten patients were treated with partial glossectomy and 18 patients with brachytherapy. No patients underwent preventive neck dissection. Subsequent cervical lymph node metastasis occurred in 15 patients

Subsequent cervical lymph node metastasis occurred more frequently in the group in which depth of tumor invasion was 5 mm or more than in the group in which it was less than 5 mm statistically measured by ultrasonography with intraoral scanner. Ultrasonography with intraoral scanner is a useful inspection method. In the future, we intend to improve the evaluation of depth of tumor invasion and to conduct further studies to assess the indications for preventive treatments in case of stage Ⅰ and Ⅱ squamous cell carcinoma of the tongue.
