Radiologic assessment preoperative to endoscopic sinus surgery.

At our institution, the screening coronal section CT scan has largely replaced the use of the sinus series for the initial evaluation of patients suspected to have sinus pathology. However, in those patients with obvious mucosal disease on endoscopic examination, the screening coronal section CT scan is bypassed and a complete coronal section CT scan obtained. Axial section CT scans are not routinely obtained and bone windows are consistently selected for viewing.
