Background: Cone-beam computed tomography (CBCT) was developed because of studies demonstrating its value in enhancing vision of the nasal cavity, lateral nasal wall, osteomeatal complex, and sinuses prior to functional endoscopic sinus surgery (FESS).

Patients and Methods: This study included a total of 30 patients with chronic sinusitis scheduled for FESS, attending
