Head and neck tumours are the sixth most common malignant tumours worldwide and, depending on the topographical relationship, may invade adjacent structures such as the maxilla and mandible [1,2]. Oral cavity and oropharyngeal locations account for half of cases. Treatment depends on the location and size of the primary tumour, the general condition of the patient, the expected treatment-related morbidity with its functional and aesthetic consequences, and the expected success of therapy [3].
