1. To review complex paranasal sinus anatomy in the preoperative setting based on an endoscopic approach and systematic imaging checklist.
2. To review important anatomic variants in sinus anatomy and how they can affect the surgical approach.
3. To describe the components of functional endoscopic sinus surgery (FESS) and review expected findings on post operative scans.
Paranasal sinus imaging anatomy and review of drainage pathways with correlation of endoscopic and virtual CT endoscopic images
Important anatomic variants and incidental findings for the sinus surgeon to consider, with emphasis on "CLOSE" mnemonic: Cribriform (Keros classification), Lamina (dehiscent?), Onodi (present?), Sphenoid (are they symmetric, is the optic nerve or carotid artery dehiscent), Ethmoid artery (is the anterior ethmoid artery present on a mesentery or embedded in bone)
Checklist for standardized imaging reports including sinus symmetry, sinus disease, drainage pathway of the frontal sinuses, frontoethmoid cell classification (ie Kuhn cells)
Review of goals and elements of functional endoscopic sinus surgery (FESS) procedure
Expected findings status post FESS
Complications and findings associated with unsuccessful FESS (such as residual uncinate) and evaluation of new patients who are candidates for revision FESS
