Fig 2. A 59-year-old man with severe dyspnea and dysphagia secondary to a large squamous cell carcinoma treated with radio-frequency ablation. A, Axial contrast-enhanced CT scan demonstrates a large necrotic tumor (arrows) in the floor of the mouth and hypopharynx. B, 3D volume-rendered reconstruction demonstrates the radio-frequency probe (Starburst XLi; RITA Medical Systems, Mountainview, Calif) and electrode deployment within the tumor by means of a submental approach. Note that the tumor anterior and posterior to the hyoid bone could be ablated simultaneously.
