Radical surgery for nasal cavity and paranasal sinus tumors.

Radical surgery for sinonasal neoplasms in combination with radiation therapy has vastly improved the outlook for these tumors. Magnetic resonance imaging (MRI) combined with high resolution computerized tomography (CT) scanning and recognition of symptoms suggestive of extensive disease has allowed more accurate determination of surgical margins. Long-term follow-up is still needed to define the limits of radical surgery necessary to treat very extensive tumors.
