Claim Text:
1. A method of treating a congested anterior ethmoid sinus comprising: i. dilating a hiatus semilunaris superior; ii. making a perforation in an anterior wall of an ethmoid bulla; iii. advancing a dilator through the perforation until it reaches an ethmoid bulla ostium; iv. dilating the ethmoid bulla ostium; and v. placing a posterior/inferior turbinate retractor between a lateral wall (LW) in a coronal plane of the ethmoid bulla ostium and a middle turbinate (MT) with placement being inferior to the ethmoid bulla and then expanding to retract the middle turbinate to improve an exposure of an uncinate process (UP), the ethmoid bulla (EB), a hiatus semilunaris superior (HSS) and a natural ostium of a maxillary sinus (NOMS).
