    Abstract:
    Computerized axial tomography (CAT) of the head provides the otolaryngologist with an effective diagnostic tool. This technique is particularly useful when used in the preoperative evaluation of head and neck pathology and may be used to define the extent of disease and to direct the surgical approach. The case of a 16-year-old male with an extensive angiofibroma involving the paranasal sinuses and nasopharynx is presented as an example of CAT in preoperative planning of the surgical procedure. Computerized tomography was used initially to define the tumor margins. Serial CAT scans were also obtained at intervals during the patient's preoperative estrogen therapy. Evidence was obtained which suggests CAT may be used to monitor the effects of preoperative hormone management of angiofibromas and in the definition of the optimal time for surgery. In the case presented the final CAT scan provided a detailed and accurate description of the tumor margins which were confirmed at surgery. Our experience with a case of an extensive nasopharyngeal angiofibroma demonstrates the CAT scan to be a useful objective diagnostic method for preoperative planning.
