摘要:

在传统继发唇裂患者的手术中，通常根据皮瓣位置切开皮肤并使用钳子。然而，这种方法无法在术前预测术后效果，尤其是患者唇部的变化。此外，在手术中，手术皮瓣的设计也较为随机，缺乏对其位置和大小的量化标准，这使得无法优化手术效果，导致手术效果依赖于手术者的手术水平。在本研究中，我们尝试使用红外扫描设备扫描患者面部，建立患者面部的三维模型，并通过有限元分析比较不同手术位置下的术后效果，尤其是比较患侧唇峰点的位移以找到最佳手术方案。通过这种方式，作者可以在唇腭裂手术前预测手术效果，使患者能够直接看到术后效果并选择最合适的方案。  

Abstract:

In traditional surgery for patients with secondary deformities of cleft lip, the skin is usually cut open, and forceps are used according to the position of the flap. However, this method cannot predict the postoperative effect before surgery, especially the changes in the patient’s lip. Moreover, in surgery, the design of the surgical flap is also quite random, needing more quantitative standards for its position and size, which makes it impossible to optimize the surgical effect, resulting in the surgical effect relying on the surgeon’s surgical level. In this study, we attempted to scan the patient’s face using infrared scanning equipment, establish a threedimensional model of the patient’s face, and compare the postoperative effects under different surgical positions through finite element analysis, especially comparing the displacement of the affected labial peak point to find the optimal surgical plan. In this way, the authors can predict the surgical effect before cleft lip and cleft palate surgery so that patients can directly see the effect after surgery and choose the most suitable scheme.
