Computed tomography of the larynx.

The normal computed tomographic anatomy of the larynx and surrounding structures is illustrated and discussed. An attempt is made to distinguish various types of tissues in cross-sectional display. The advantages of computed tomography over other modalities used for imaging the laryngeal region include the capacity to depict structural relationships in cross-section, to better define cartilaginous involvement by adjacent neoplasms, and to identify vascular components with contrast enhancement. The clinical application of computed tomography with respect to radiation therapy treatment planning of laryngeal tumors in an important feature of this imaging technique.
