CT evaluation of paranasal sinus tumours for cranio-facial resection.

Twenty-two patients with tumours of the paranasal sinuses had computerised tomography performed prior to cranio-facial resection. The findings of CT, histology and operative appearances are compared and a 78% correlation found. The radical approach offered by cranio-facial resection allows more accurate confirmation of CT findings than hitherto possible. The particular importance of CT scanning in relation to tumours of paranasal sinuses is discussed.
