Abstract:

The change of the nasal structure can cause a change of the nasal aerodynamics, then cause a self-adaptation change of the inferior turbinate. A number of patients with nasal septum deviation are chosen to do the diorthosis, some of them with the movement of inferior turbinate bone. CT scanning is carried out for all patients both before and after the surgery, then a three-dimensional reconstruction is done for the nasal airway according to the CT data, to analyze the characteristics of the nasal aerodynamics with the method of the computational fluid dynamics. It is shown that the purpose of the corrective procedure for the nasal structure is not for the bilateral nasal symmetry of the volume,but with the nasal structure as an integral whole, to protect the nasal `green belt', in order to remodel the nasal cavity, and to recover the nasal physiologic function.
