Nasal conditioning after endonasal surgery in chronic rhinosinusitis with nasal polyps

Background: Endoscopic sinus surgery (ESS) is a frequently performed operation for chronic rhinosinusitis (CRS). The aim of this study was to investigate nasal conditioning after ESS with/without septoplasty and turbinoplasty in patients with CRS with nasal polyps and to determine its relation to nasal patency and geometry. Methods: Twenty-one patients were enrolled into this study. Nasal conditioning, AAR, and acoustic rhinometry were measured before and 4-8 months after endonasal surgery. Results: The temperature and humidity gradient across the nose increased significantly after operation. High nasal volumes and patency were positively correlated with elevated nasal conditioning. No correlation between preoperative and postoperative changes in nasal geometry and nasal airflow with changes in conditioning values was found. Conclusion: Patients with CRS with nasal polyps seem to profit from ESS with/without septoplasty and turbinoplasty because nasal conditioning is improved postoperatively. Properly performed ESS has its importance within the variety of nasal surgical procedures ensuring improved nasal function.
