Two cases of severe laryngeal injuries were evaluated by computed axial tomography (CT). Results of these studies correlated well with surgical findings and were helpful in planning structural repair. Axial views obtained by laryngeal CT were distinctly superior to the bidimensional picture obtained by polytomography. In addition, the method proved more advantageous than contrast laryngography, which is often impossible to perform in the presence of massive swelling.
