Introduction: oral cavity neoplasia is rare with squamous cell carcinoma being one of the most common histological type. The most important prognostic factors are size of the primary tumor and lymph node invasion. Elective neck dissection has been considered only in cases with clinically negative neck nodes, according to risk factors for neck disease. Sentinel node biopsy (SNB) has appeared to be an alternative to complementary neck dissection, only in cases of positive SNB. Materials and methods: the clinical records of 10 patients with T1 to T3 squamous cell carcinomas were reviewed retrospectively. Al of them underwent surgical treatment of the primary lesion and neck lymph nodes at the same time. Patent blue was used to identify the sentinel node in the neck in 10 cases and technetium-99 colloid in 8. A supraomohyoid neck dissection (SOHND) was performed in 8 of the 10 patients. Results: most sentinel nodes were found at level IIA. There was one false negative result. Regional control was obtained in 8 of the patients (80%) but 2 patients died with regional disease: one with a pN+ SNB and SOHND and another with pN- SNB without SOHND. Conclusions: we have reviewed our initial experience on SNB in cancer of the oral cavity, and particularly technical aspects of the SNB in the neck, a well-known more complex anatomical region. SNB should be performed systematically in T1 and T2 lesions of the tongue and foor of the mouth and eventually, for more advanced tumors in order to improve the learning curve until international trials results recommend a complementary neck dissection only in case of positive SNB.
