[Cancer of the larynx and computed x-ray tomography: exploration of the hypothyroepiglottic area and paraglottic space].

Twenty patients with laryngeal cancer were explored by tomography and a CT scan. Results were compared between cases and, for operated patients, with histosurgical findings. Results of this study and a review of the literature suggest that the CT scan is the most adapted examination for exploration of the paraglottic and hypothyroepiglottic spaces, but that caution should be exercised when assessing results.
