title: Pitfalls in the surgical management of cancer of the larynx and hypopharynx.
abstract: This article is based on findings in 180 patients with cancer of the larynx and hypopharynx. Positive margins were found in 12.2% (22/180) of all tumors, 12.5% (8/64) of supraglottic tumors, 16% (4/25) of transglottic tumors, 5.3% (2/38) of glottic tumors, 11.1% (2/18) of pyriform fossa tumors, 50% (3/6) of posterior pharyngeal wall tumors, and 10.6% (3/29) of postcricoid tumors. The relationship between the inadequate surgical margins of the specimens, tumor spread, preoperative CT findings, and surgical procedures performed have been correlated.
