Abstract
Aim: The aim of the study was to compare the flow disturbances in computational fluid dynamics (CFD) technique based on computed tomography (CT) to the results of active anterior rhinomanometry (RMM), in patients with nasal septum deviation (NSD). Material and methods: In 24 patients with NSD, RMM and CT of the paranasal sinuses were performed as a part of typical clinical management. For each patient, 3D models of air-filled spaces in the nasal cavity were created, based on CT images, and air flow simulations during inhalation were performed using CFD technique. Correlations between RMM, both before and after anemization, during inspiration, and CFD were tested, independently for the left and right side. Results: The obtained correlation coefficients for the comparison of flow in RMM during inspiration and in CFD during simulated inspiration were: before anemization 0.46 for the left side and 0.52 for the right side, after anemization 0.65 for the left side and 0.61 for the right side (p < 0.05). Conclusions: Moderate correlation was found between the results of real and virtual rhinomanometry, with higher correlation coefficients obtained after anemization, compared to the values before anemization.
