t rans-oral robotic surgery for tongue cancer background: The traditional treatment of oropharyngeal cancer was based mainly in radio and che motherapy, aiming to avoid organ excisions. However, the adverse effects of these therapies prompted the development of new therapies. Among these, trans-oral robotic surgery (TORS) has promising results. case reports: We report two patients operated using this technique. An 82 years old woman treated for a tumor in the base of the tongue six years ago with radiotherapy. A new lesion in the tongue was found and excised by TORS uneventfully. The pathology report confirmed the complete excision of the malignant lesion. A 57 years old male with a history of palate cancer treated with radiotherapy in 1990. In 2013 a submandibular mass was biopsied confirming the presence of a squamous carcinoma metastasis. During a bilateral suprahyoid dissec tion, a tumor in the base of the tongue was found. In a second intervention the tumor was excised by TORS. The pathology reports tumor free borders but near the lesion. Postoperative radiotherapy was recommended.
