Since the posterior ethmoids have an independent drainage route (green check), they are not always involved with the obstructions seen in the anterior ethmoid, frontal, and maxillary sinuses. These three sinus groups share a drainage pathway below the middle turbinate. Disease processes that involve all of the sinuses more likely represent an underlying mucosal inflammatory process or a widespread infection.
