The accuracy and clinical usefulness of both computed tomography (CT) and laryngography were evaluated in 30 patients with carcinoma of the larynx. The radiologic results were correlated with the surgical and pathologic findings. The accuracy in determining tumor compartmental localization (supraglottic, glottic, or subglottic) was as follows: CT provided the correct diagnosis in 26 cases. There were three false negative and one false positive diagnoses. Laryngography provided the correct diagnosis in 19 cases. There were six false negative and six false positive diagnoses. In virtually all cases, CT provided information equivalent to or more accurate than laryngography. CT is recommended as the radiologic procedure of choice when additional diagnostic information is required to supplement the findings of laryngoscopy in determining the feasibility of conservation surgery.
