• The surgical specimens from total laryngectomy and partial pharyngectomy in 20 consecutive cases of piriform sinus carcinoma were studied by whole-organ serial sectioning in the horizontal plane. There had been gross clinical involvement or fixation of the vocal cord in 19 of these cases. Histopathologic evidence of cartilage invasion or piriform apex involvement was found in 17 specimens. In 13 cases, it appeared, retrospectively, that the cancer could have been adequately encompassed without resecting the entire contralateral side of the larynx. When this element is spared, a sphincteric speaking shunt can be made. Careful preoperative assessment would have correctly predicted the suitability or danger of this approach in 18 of the 20 cases; the two indeterminate cases would have required intraoperative quick section. These findings have meaningful implications regarding the scope of conservation surgery in piriform carcinoma.
