What is mucosal opacification of maxillary infundibulum?

A doctor has provided 1 answer

Blockage of sinus: The extremely narrow space allowing air to enter the maxillary sinus (sinus under the eye) and allow drainage from that sinus is called the infundibulum. Opacification of that narrow channel is the first phase of acute inflammation of that sinus. If this blockage becomes chronic, a rhinologic surgeon can open that passage and allow resolution of problem.
