Numerical Simulation of the Granulation Tissue Resection Operation in Human Trachea
To quantitatively analyze the aerodynamic changes in patient's trachea after the resection operation of hyperplastic granulation tissue, computational fluid dynamic (CFD) method was utilized to perform the simulation. Firstly, three dimensional finite element model of the patient’s trachea before and after surgery were reconstructed based on CT images; secondly, the numerical simulation based on CFD method was performed to investigate the changes in aerodynamic changes in patient's trachea after excision. Results indicated that the dyspnea symptom was largely alleviated after the removal surgery, the abnormal morphology was obviously improved and the resistance of trachea was decreased significantly. Present research also demonstrates that CFD methods can be used to quantitatively evaluate the postoperative effects of the granulation tissue resection operation.
期刊介绍：
The field of biomechanics concerns with motion, deformation, and forces in biological systems. With the explosive progress in molecular biology, genomic engineering, bioimaging, and nanotechnology, there will be an ever-increasing generation of knowledge and information concerning the mechanobiology of genes, proteins, cells, tissues, and organs. Such information will bring new diagnostic tools, new therapeutic approaches, and new knowledge on ourselves and our interactions with our environment. It becomes apparent that biomechanics focusing on molecules, cells as well as tissues and organs is an important aspect of modern biomedical sciences. The aims of this journal are to facilitate the studies of the mechanics of biomolecules (including proteins, genes, cytoskeletons, etc.), cells (and their interactions with extracellular matrix), tissues and organs, the development of relevant advanced mathematical methods, and the discovery of biological secrets. As science concerns only with relative truth, we seek ideas that are state-of-the-art, which may be controversial, but stimulate and promote new ideas, new techniques, and new applications.
