title: Clinical, radiological and surgical correlation in cancers of the paranasal sinuses.
abstract: Clinical, radiological and CT findings for each adjacent subsite were tabulated and compared in 25 consecutive cases undergoing surgery for malignant lesions of the maxillo-ethmoid complex. It was found that tumour extensions into nose, palate, cheek and orbit were identified correctly in a high proportion of cases clinically and radiologically. Posterior extensions into infratemporal or pterygopalatine fossae were evident clinically in only one out of 5 cases. Clinical assessment failed to detect orbital invasion in 3 out of 7 cases, while CT missed orbital periosteal involvement in one case. CT overestimated spheno-ethmoidal extensions of tumour in 44% (8/18) cases.
