摘要:

继发唇裂畸形是一种常见的口腔颌面部畸形，通常伴随上唇和鼻裂。继发唇裂畸形的主要治疗方法是手术修复。其中，上唇瓣修复是一种常见的方法；其原理是将健康组织移植到病变部位以达到修复的目的。然而，在手术过程中，各关键点的应力分布和应变情况差异较大。因此，在修复手术中应特别注意各关键点的力学特性，以确保手术效果。本文旨在建立三维有限元模型并进行有限元分析，模拟继发唇裂上唇瓣修复手术的力学特性和关键点位移，以提高手术成功率和安全性。  

 Abstract:

Cleft lip secondary deformity is a common oral and maxillofacial deformity, usually accompanied by the upper lip and nasal cleft. The main treatment method for cleft lip secondary deformity is surgical repair. Among them, upper lip flap repair is a common method; the principle is to transplant the healthy tissue to the lesion site to achieve the purpose of repair. However, during the surgical process, each key point’s stress distribution and strain conditions are quite different. Therefore, special attention should be paid to the mechanical properties of each key point during the repair operation to ensure the surgical effect. This paper aims to establish a 3dimensional finite element model and perform finite element analysis to simulate the mechanical properties and key point displacement of the upper lip flap repair operation for cleft lip secondary deformity to improve the operation’s success rate and safety.
