Abstract/OtherAbstract:
OBJECTIVE: To investigate the aerodynamic consequences of conservative unilateral inferior turbinate reduction using computational fluid dynamics methods to accomplish detailed nasal airflow simulations. DESIGN: A high-resolution, finite-element mesh of the nasal airway was constructed from magnetic resonance imaging data of a healthy man. Steady-state, inspiratory airflow simulations were conducted at 15 L/min using the techniques of computational fluid dynamics. INTERVENTION: Circumferential removal of 2 mm of soft tissue bulk along the length of the left inferior turbinate was modeled. MAIN OUTCOME MEASURES: Nasal airflow distribution and pressure profiles were computed before and after simulated left inferior turbinate reduction. RESULTS: Simulated inferior turbinate reduction resulted in a broad reduction of pressure along the nasal airway, including the regions distant from the inferior turbinate vicinity. In contrast, relative airflow changes were regional: airflow was minimally affected in the valve region, increased in the lower portion of the middle and posterior nose, and decreased dorsally. CONCLUSION: Use of computational fluid dynamics methods should help elucidate the aerodynamic significance of specific surgical interventions and refine surgical approaches to the nasal airway.
