Chronic panrhinosinusitis without nasal polyps: long-term outcome after functional endoscopic sinus surgery.

OBJECTIVE: The goal of this study was to evaluate the long-term outcome after functional endoscopic sinus surgery (FESS) for chronic panrhinosinusitis without nasal polyps by using symptom scoring and an endoscopic outcome evaluation. STUDY DESIGN: Seventy-seven patients with chronic panrhinosinusitis without nasal polyps (Kennedy computed tomography [CT] scan stages I to III) were followed up for at least 3 years after FESS. Preoperative evaluation included a CT scan and an immunoallergologic evaluation. Three years after FESS, all patients were interviewed and scored endoscopically. RESULTS: Ninety-two percent of the patients showed a marked global improvement after FESS. The endoscopic control showed normal findings in 54% of all ethmoidal cavities. The postoperative endoscopic score correlated significantly with the subjective satisfaction ratings (P < 0.001). The preoperative CT staging proposed by Kennedy was predictive for necessity of revision surgery in 15% of the patients. CONCLUSIONS: Our data suggest that FESS for chronic panrhinosinusitis without nasal polyps has a good long-term outcome on subjective symptoms and endoscopic findings. SIGNIFICANCE: According to this study, subjective improvement correlates significantly with the postoperative endoscopic findings in the ethmoidal cavities of patients with chronic panrhinosinusitis without polyps at a long-term follow-up.
