Sinus computed tomography, coronal view of a frequent airline traveler with recurrent episodes of bilateral maxillary and ethmoid pain during ascent (reverse squeeze), associated with bilateral V2 trigeminal nerve anesthesia versus tingling sensation. Bilateral concha bullosa were noted to compress the ostiomeatal complexes (OMC) and narrow the bilateral maxillary infundibulae, in addition to mild septal deviation–broad septal width and profound inferior turbinate hypertrophy. Treatment for this presentation of recurrent acute barosinusitis is noted in the accompanying text.
