Objectives/Hypothesis The aim of the investigation was to determine the influence of complete resection of the turbinates and the lateral nasal wall on nasal deposition of particulate matter with an aerodynamic diameter of 10 μm or less (pm 10 ) and its relation to nasal patency and geometry. Study Design Retrospective study. Methods Eight patients were enrolled in the study after unilateral sinus surgery for a unilateral inverted papilloma of the sinuses. Particle deposition from the inhaled and exhaled air was measured by means of a laser particle counter in the nasal valve area and the nasopharynx during nose‐only breathing and nose‐in, mouth‐out breathing. The data on deposited fraction for the operated side were compared with the data for the untreated, healthy side. Rhinomanometry and acoustic rhinometry were performed. Results Particle deposition did not differ significantly between the operated and untreated sides of the nose at both detection sites. No correlation between the deposited fraction and rhinomanometric and rhinometric values was found. Conclusion Radical resection of the turbinates does not seem to disturb particle deposition (pm 10 ) measured in the nose to a significant degree. Factors other than impaction and sedimentation onto the mucosal surface of the turbinates seem to be sufficient for effective particle deposition after radical removal of the turbinates.
