Endoscopic sinus surgery (ESS) offers many benefits to patients with extensive chronic sinusitis and nasal polyps. Olfaction disorder have been documented as the most uncontrollable complaint associated with ESS, and recognition of this finding suggests that the treatment of olfactory clefts is essential for dysosmia therapy. In this paper, endoscopic surgery procedures for inflammatory lesions in the olfactory cleft are described and postoperative findings are presented. From April 1, 1995, through March 31, 1999, the author operated on 60 patients (101 sides) with inflammatory lesions, such as polyps or polypous swellings, in the olfactory cleft. The average follow-up period was 338 days. The key points in the surgical technique are the cauterization of the edematous mucosa using high-frequency radiosurgical equipment (Surgitoron™), allowing both the middle and superior turbinate to remain unresected, and the opening of the sphenoethmoidal recess to insure sufficient space for the olfactory stream. In addition, endoscopic treatment during the follow-up period appears to be essential for successful treatment in cases of chronic sinusitis. The postoperative findings in the olfactory cleft at the time of final observation were evaluated according to three categories: patent, adhesion and obstruction due to recurrence. Eightyseven sides (86.1%) were patent, 5 sides (5.0%) exhibited adhesion, and 5 sides (5.0%) were obstructed. Olfaction was subjectively evaluated before and after surgery. Fifty patients (83.3%) did not experience dysosmia after surgery and 10 patients experienced no changes in olfaction.
