Comparison of preoperative computed tomographic findings with postoperative histopathological findings in laryngeal cancers

Abstract: In this study of 22 patients with laryngeal cancer, computed tomographic (CT) scans in the axial plane were compared with histopathological sections prepared in the same plane. The value of the preoperative CT for evaluating tumor invasion, location and size was then investigated. Findings demonstrated that CT was most sensitive in determining tumor invasion to the paralaryngeal and preepiglottic spaces, anterior and posterior commissures and subglottis. In contrast, CT was less sensitive in determining actual… Show more

“…A íntima relação entre a mucosa e a cartilagem na comissura anterior facilita a extensão tumoral (10) . A comissura anterior é prontamente evidenciada na TC, possui configuração característica e é bem avaliada por este método (11,12) . O real envolvimento desta região pode não ser observado na laringoscopia (13) .…”

“…Os tumores glóticos nesta região podem invadir a articulação cricoaritenóide e a submucosa do ápice do seio piriforme (17) . Os carcinomas que se originam na região aritenóide ou interaritenóide apresentam tendência a estender-se de forma submucosa (12) . A TC pode não ser confiável na existência de reações actínicas intensas nos diversos níveis analisados (18) .…”
