Abstract:
Pathologies leading to Nasal Breathing Difficulties (NBD) represent one of the most common medical conditions, and carry heavy social costs. However, the state of the art in dealing with NBD and their surgical treatment is that no rational means are available to link every single anatomic anomaly (and its surgical modification) to the overall flow quality within the nasal airway.
The seminar will describe the essential steps of a CFD-based, patient-specific procedure we are conceiving to help ENT surgeons in their daily practice. Our procedure relies on the CT scan of the patient as an input, and outputs a detailed three-dimensional, time-dependent flow field within the nasal cavity.
Key points of our procedure are that i) it must be "cheap" enough to be realistically useable in the clinical daily practice; ii) its robustness and reliability must be proven not only in terms of prediction of global flow quantities, but also with respect to details of the flow where the surgeon is expected to operate.
