dc.description.abstract |
Background: The aim of this study was to investigate using computational fluid dynamics (CFD) the effects on nasal aerodynamics of two different techniques for reducing the inferior turbinate. This may assist in surgical planning to select the optimal procedure.
Methods: Virtual surgery using two techniques of turbinate reduction was performed in eight nasal airway obstruction patients. Three bilateral nasal airway models for each patient were compared: 1) Pre-operative 2) Bilateral inferior turbinoplasty 3) Bilateral total inferior turbinate resection (ITR). Two representative healthy models were included. CFD modeling of airflow was performed under steady-state, laminar, inspiratory conditions.
Results: Nasal airway resistance was slightly more reduced following ITR compared to turbinoplasty due to loss of the pressure gradient at the head of the IT. Turbinoplasty resulted in ventilation, pressure and wall shear stress profiles closer to those of healthy models. A more prominent jet-like course of the main flow stream was observed inferiorly in the ITR group.
Conclusions: Nasal air conditioning was significantly altered following IT surgery. Overall differences between the groups were small and are unlikely to bear influence on nasal function in normal environments. Further studies using a larger number of patients and healthy subjects are required, attempting to establish a clinical correlation with long-term outcomes such as the perception of nasal patency, mucosal crusting and drying, and air conditioning in different environments. Since a large proportion of IT mucosa remains following turbinoplasty, future dependence on topical therapy should also be considered. |
