After the biomechanical finite element analysis for the three-dimensional reconstruction model, we find the structure of the deformed nose showes the following characteristics: 1, Nasal septum, nasal columella, lateral feet of nasal alar, lateral nasal dorsum are stress concentrated regions, that is the key mechanical positions of deformed nose; 2, Under the static state, nasal deformation has a very small value of stress distribution, under displacement load status, the deformed nasal has a large value of the stress distribution; 3, Ipsilateral nasal columella are the the key mechanical parts of deformed nasal rectify. And lateral nasal alar is also the most stress concentrated areas.

对于重建后的单侧唇裂鼻畸形鼻部模型进行有限元生物力学研究，发现畸形鼻的力学结构呈现以下特点：1、鼻中隔、鼻小柱、鼻翼外侧脚、鼻背外侧是单侧唇裂鼻畸形应力分布的集中部位，也就是畸形鼻部的力学关键部位；2、在静态状态下，畸形鼻部拥有的应力分布值很小，在位移载荷状态下，形变后的畸形鼻部拥有的较大的应力分布值；3、单侧唇裂鼻畸形整复中，鼻小柱患侧部是畸形整复的力学关键部位，其次就是患侧鼻翼部。
