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.

It suggested that under static status, the nasal septum, nasal columella and the lateral feet of nasal alar were the most concentrated areas of stress distribution. They are key mechanical parts of deformed nasal.3.2 Nasal displacement load analysis of patients with unilateral cleft lip and nasal alar collapse Deformed nasal displacement load three-dimensional finite element analysis showed that if the ipsilateral and contralateral nasal parts obtain similar geometry, the positions around nasal columella in ipsilateral nostril were the most stress concentrated region, next parts were the nasal septum and the lateral nasal alar.
