Physical Conditions Prevailing in the Nasal and Maxillary Sinus Cavities Based on Numerical Simulation.

: This paper presents a unique study that links the physical conditions in the nasal passage with conditions that favour the development of bacterial strains and the colonization of the mucous membranes of the nose and paranasal sinuses. The physical parameters considered were air flow, pressure, humidity, and temperature. : Numerical models of the human nose and maxillary sinus were retrospectively reconstructed from CT images of generally healthy young subjects.
