Presentation transcript:

An 89-year-old man with supraglottic laryngeal cancer. An 89-year-old man with supraglottic laryngeal cancer. A and B, The standard neck CT images at the supraglottic (A) and glottic (B) levels show a large soft-tissue mass involving the pre-epiglottic space (arrow) and right aryepiglottic fold, extending to the right true vocal cord (arrowhead). C and D, Coronal (C) and sagittal (D) reformatted images of the standard neck CT scan show transglottic extension of the tumor without subglottic extension. E and F, Dedicated laryngeal CT images with straw-blowing (E) and breath-holding (F) at the level of true vocal cord show no change in the location of vocal cord, indicating the fixed vocal cord. Clinically, vocal cord mobility is impaired but not fixed. This is staged as T3 for pre-epiglottic extension. K. Gilbert et al.
