New Management Strategies of Oral Tongue Cancer in Bangladesh.

Introduction: Malignancies of the tongue represent one of the greatest management challenges for the maxillofacial surgeons as well as oncologists, because of the adverse effects of treatment on oral and pharyngeal function, the eventual quality of life, and the poor prognosis of advanced disease.
