title: Sinusitis: postoperative changes and surgical complications.
abstract: Functional endoscopic sinus surgery (FESS) is the standard of care for the surgical management of sinonasal inflammatory disease. This group of procedures focuses on the sinus outflow tract, and is designed to improve sinus function by restoring sinonasal physiology. Use of the monocular endoscope is associated with a range of unique surgical complications that often require cross-sectional imaging. Many patients considering sinus surgery today have had surgical procedures in the past that were directed at removing diseased mucosa, rather than improving sinus drainage, and have a different appearance on CT. This report addresses the spectrum of surgical changes found on postoperative imaging of the paranasal sinuses, and the surgical complications that may occur during endoscopic sinus surgery.
