ABSTRACT: By Computational Fluid Dynamics (CFD) Method eliminate the difficulties in analysis of Trachel Airway Management.

METHODS : The processes currently used to diagnose this condition are unpleasant for any patients specially for children, and in some cases aggravate the obstructed airway. In order to analyze the effects of difficulty in airway management, computational fluid dynamics (CFD) can be applied to study the airflow and pressure differences induced along the trachea. The process began by obtaining a computed tomography (CT) scan of the airway of a patients suffering from tracheomalacia. Using MIMICS (Materialise, Leuven, Belgium) software, the CT scan was converted into a three-dimensional (3D) computer model in standard transformation language (STL) format. Magics (Materialise, Leuven, Belgium) software was then used to refine the computer model. The STL file was then imported into CFD analysis software FLUENT (Ansys, Lebanon, USA). Airflow simulations were then run, and results were compared to properties of a normal airway and displayed through computer 3D modelling and visual representation. In order to provide a physical representation of the affected paediatric airway, physical 3D models were also created from the same STL files that were used for the CFD analysis, using the additive manufacturing process called selective laser sintering.
