[Value of computed tomography in tumors of the pharyngolarynx].

A study was conducted of 27 case-reports to assess the value of computed tomography for investigation of pharyngolaryngeal cancer spread. Analysis was by comparison of clinical, endoscopic, conventional radiologic, computed tomography, and definitive operative specimen histologic findings. Certain laryngeal structures were studied more particularly: the anterior commissure, the pre-epiglottic spaces, the subglottic region, and the thyroid cartilage. Findings demonstrated that the CT Scan is of no value for the study of the anterior commissure and the pre-epiglottic spaces, but is of major interest for detection of subclinical lesions of the subglottic region and thyroid cartilage.
