摘要:

本文提出了第一次评估的可行性有限元建模的眼眶减压术,在突眼的背景下。首先进行模拟与从病人TDM考试中提取的数据。结果似乎定性验证的可行性的模拟,与有限元分析,收敛,并提供了一个向后移动的眼球与脂肪组织通过鼻窦的位移。该有限元模型可以帮助外科医生制定眼球突出复位的计划,特别是减压孔的位置和大小。为了估计受手术影响的脂肪组织体积,分析模型似乎提供了等效效率的更快结果。

英文摘要:

This paper presents a first evaluation of the feasibility of Finite Element modelling of the orbital decompression, in the context of exophthalmia. First simulations are carried out with data extracted from a patient TDM exam. Results seem to qualitatively validate the feasibility of the simulations, with a Finite Element analysis that converges and provides a backward movement of the ocular globe associated with displacements of the fat tissues through the sinuses. This FE model can help a surgeon for the planning of the exophthalmia reduction, and especially for the position and the size of the decompression hole. To get an estimation of the fat tissues volume affected by the surgery, an analytical model seems to provide quicker results for an equivalent efficiency.
