Objectives: Use of computational fluid mechanics (MFC) in understanding the impact of the size and location of septal perforations (PS) on nasal physiology Study design: Computer simulation study. Material and Methods: MFC software (Flowgy®) was used to create digital models of nasal cavities through computed tomography reconstruction. Virtual surgery was performed with establishment of anterior (1 or 2 cm) and posterior (1 or 2 cm) PS. Results: Larger perforations cause a greater change in the allocation of airflow regardless of location, with air deviation from the nasal cavity with greater flow to the one with less flow. Bilateral nasal resistance was not significantly altered by the presence of PS. Conclusions: MFC technologies help to understand how PS change nasal physiology. Airflow allocation is altered, with greater airflow through the less resistant nasal cavity, especially in anterior perforations.
