Eleven patients with olfactory disturbances caused by inflammation of the ethmoid sinuses are reviewed, and the functional results of endonasal surgery are evaluated.Rhinoscopic examination showed the presence of a purulent discharge and mucosal thickening of the superior meatus.Radiographic examination showed opacity in the ethmoid sinus and the olfactory region.A standard olfactory acuity test, each side separately in 9 patients and both sides together in 2 patients (20 tests in 11 patients), and an intravenous olfaction test with alinamine were performed before and after surgery.The standard olfactory acuity test showed that 16 out of 20 (80%) recovered more than 1 grade in the detection threshold, and 15 out of 20 (75%) recovered more than 1 grade in the recognition threshold after endonasal ethmoidectomy.We conclude that patients with olfactory disturbance caused by ethmoid sinusitis can expect good results of surgical treatment.
