1- Anatomical sum-up about sinonasalcavities and their critical variants. 2- Illustration of some cases of sinonasaltumours and emphasize the complementarity of the CT& MRI couple in the preoperative assessment.
Sinonasal malignant tumours are rare and represent 3% of cancers of the upper aerodigestive tract. They offer a range of histological types dominated by epithelial tumours. They develop in confined anatomical spaces,
and come out by mild and non-specific clinical signs,causing a delay of diagnosis. Thus multi-disciplinary management ofsinonasal tumours is necessary,
starting with a complete clinical assessment combined with an endoscopic study of the nasal cavities and the nasopharynx,...

I- Anatomicalsum-up about sinonasal cavities: Although complicated,
adequate knowledge of paranasal sinuses is essential in order to guide functional endoscopic surgery. CT is the modality of choice in imaging offering multiplanar reconstruction. It retains a place for pre-surgical morphological assessment as well as for the analysis of bone structures of the facial bone and skull base. What is the technique of CT? - Patient in supine position and axial images of the sinuses are acquired with...
The preoperative workup of sinonasalmalignant tumours is based on the CT - MRI couple,
which are complementary to guide follow-up and therapy.
