Twelve-year long-term postoperative outcomes in patients with chronic rhinosinusitis with nasal polyps

Background: Evidence regarding long-term postoperative follow-up of chronic rhinosinusitis with nasal polyps (CRSwNP) patients is scarce in the literature. The objective of the present study was to report long-term 12-year postoperative outcomes for CRSwNP patients.Methods: CRSwNP patients were prospectively followed after endoscopic sinus surgery. Sinonasal symptoms, nasal polyp score (NPS), Barcelona Smell Test 24 (BAST-24), Lund-Mackay Score (LMS), and Medical Outcome Study Short Form-36 (SF-36) question-naire were assessed before and 12 years after surgery.Results: At long-term follow-up (median, 12 years), a strong improvement was noted for all patients (N=76) in nasal symptoms score, NPS, BAST-24, and LMS scores compared with baseline. No long-term improvement in SF-36 was found.Conclusion: Patients with CRSwNP have a long-term 12-year postoperative improvement in nasal symptoms, polyp size, compu-ted tomography, and olfaction.
