    ABSTRACT: Complaints like impaired respiration capabilities or a reduced sense of smell and taste are common for pathologically shaped nasal cavities. The Lattice-Boltzmann Method (LBM), which is particularly suited to simulate flows in intricate geometries, is used to analyze the influence of the geometry of the nasal cavity on the pressure loss in a non-invasive pre-surgical step to support surgical decision processes. Another important function of the nasal cavity is the moisturization and heating of the inhaled air. To analyze complaints caused by a diminished heating function a passive scalar convection-diffusion equation for the temperature is solved by a Thermal Lattice-Boltzmann Method. After a successful validation of the method for the flow over a heated isothermal flat plate, a comparison of the functionalities of a modified nasal cavity after rhino-anaplasty and a cavity with swollen turbinates is performed to understand the influence of the geometry on the breathing capability and the ability to heat up the inhaled air.

    ABSTRACT: The flow in a real human nose is numerically simulated at steady inspiration and expiration. The analysis uses a Lattice Boltzmann method (LBM) which is particularly suited for flows in extremely intricate geometries. The nasal geometry is extracted from computer tomography (CT) data using a so-called reconstruction pipeline. Thus, for any nose the surface geometry can be defined and a numerical mesh can be generated. The focus of this investigation is on the analysis of the flow field at steady inspiration and expiration with respect to secondary flow structures. It is evidenced that strong vortical structures appear near the throat at inspiration forming a pair of counter-rotating vortices which disappear at expiration. Overall, at exhalation less vorticity is generated in the flow than at inhalation.

  • Article: Computational fluid dynamics: a suitable assessment tool for demonstrating the antiobstructive effect of drugs in the therapy of allergic rhinitis.
    N Achilles, N Pasch, A Lintermann, W Schröder, R Mösges
    [show abstract] [hide abstract]
    ABSTRACT: This systematic review aims first to summarize the previous areas of application of computational fluid dynamics (CFD) and then to demonstrate that CFD is also a suitable instrument for generating three-dimensional images that depict drug effects on nasal mucosa. Special emphasis is placed on the three-dimensional visualization of the antiobstructive effect of nasal steroids and antihistamines in the treatment of allergic rhinitis. In the beginning, CFD technology was only used to demonstrate physiological and pathophysiological airflow conditions in the nose and to aid in preoperative planning and postoperative monitoring of surgical outcome in the field of rhinosurgery. The first studies using CFD examined nasal respiratory physiology, important functions of the nose, such as conditioning and warming of inspired air, and the influence of pathophysiological changes on nasal breathing. Also, postoperative outcome of surgical procedures could be "predicted" using the nasal airflow model. Later studies focused on the three-dimensional visualization of the effect of nasal sprays in healthy subjects and postoperative patients. A completely new approach, however, was the use of CFD in the area of allergic rhinitis and the treatment of its cardinal symptom of nasal obstruction. In two clinical trials, a suitable patient with a positive history of allergic rhinitis was enrolled during a symptom-free period after the pollen season. The patient developed typical allergic rhinitis symptoms after provocation with birch pollen. The 3-D visualization showed that the antiallergic treatment successfully counteracted the effects of nasal allergen provocation on nasal airflow. These observations were attributed to the antiobstructive effect of a nasal steroid (mometasone furoate) and a systemic antihistamine (levocetirizine), respectively. CFD therefore constitutes a non-invasive, precise, reliable and objective examination procedure for generating three-dimensional images that depict the effects of drugs used in the treatment of allergic rhinitis.
