title: Computed tomography in the management of head and neck cancer.
abstract: Computed tomography is indispensable in determining the deeper extensions of tumors and proper treatment planning as well as in documentation of tumor resolution for lesions arising in the nasal cavity, paranasal sinuses, orbit, and salivary glands. In the hypopharynx and larynx, computed tomography provides information of differing degrees of value according to the clinical stage, site of origin, and usual therapeutic approach for each tissue. Detection of subclinical cervical adenopathy needs further investigation. Computed tomography has not been of particular value for lesions arising in the oral cavity and oropharynx.
