MDCT as the mainstay in paranasal sinus imaging

Dear users,

The paranasal sinuses can be affected by a variety of pathological conditions, from inflammatory diseases to benign and malignant lesions and traumatic injuries. The most widely used and accurate imaging method for evaluating disorders of these structures is MDCT, which provides detailed information about both bony and soft tissues, helps differentiate inflammatory from neoplastic processes, and allows the most reliable preoperative evaluation prior to endoscopic sinus surgery.

In this month’s newsletter, the advantages of MDCT scanning in the clinical assessment of the paranasal sinuses are highlighted in Professor Ertl-Wagner’s Focus on and in three new clinical cases. The practical application of MDCT in this setting is supported by scientific data illustrated in the selected literature and in the e-book here proposed.

We remind you that suggestions for new topics to be covered in future issues are welcomed: please contact us at
