@ENTHouse brought to my attention a FANTASTIC website that literally identifies and goes through all anatomic structures on every slice of a CT or MRI scan of the head. Sinus cavities, blood vessels, nerves, bone, suture lines, etc... Wish I thought of doing it first... It may be a bit confusing for a layperson, but if you have a copy of your CT/MRI scan and wonder where the maxillary sinus or optic nerve is located on your scan, check this website out and you probably can figure it out…
