目的在面瘫患者中，可能需要面部复活手术以使面部软组织功能/运动正常化。鼻唇皱褶(NLF)的动态变化是这种正常化的关键。这项前瞻性观察性研究的目的是确定单侧面瘫患者和正常受试者NLF的3D形态动力学。背景和样本人口收集来自单侧面瘫成人(Bell‘s面瘫，n=36)的3D面部软组织运动数据；和(2)年龄和性别频率匹配的对照组(n=68)。材料和方法使用基于视频的运动捕捉系统从参与者的重复动画中收集运动数据。在侧面、垂直和深度平面上分析了NLF、鼻部和周口部的移位和不对称性，以及NLF和NLF相对于下唇中线的运动。结果与对照组相比，NLF患者的平均位移较小，平均不对称性较大，运动不协调程度较大。两组微笑时NLF和连合标志物的移位幅度大致相同(控制范围为11~14 mm；患者范围为7~10 mm)。结论微笑时NLF的动态变化与口腔连合偏移一样显著。因此，固定的NLF是面部动画的一个不自然的特征。必须考虑对受损的NFL运动进行手术治疗，以创造更自然的手术结果，特别是在微笑期间。
ObjectivesIn patients with facial paralysis, facial reanimation surgery may be needed to normalize facial soft tissue function/movements. Critical for this normalization is the dynamics of the nasolabial folds (NLFs). The objective of this prospective, observational study was to determine the 3D morphologic dynamics of the NLFs in patients with unilateral facial palsy and normal subjects.Settings and Sample Population3D facial soft tissue movement data collected from adults with unilateral, facial paralysis (Bell's Palsy, n = 36); and (2) an age‐ and sex‐frequency matched control group (n = 68).Materials and methodsMovement data were collected during repeated animations from participants using a video‐based motion capture system. Movement in terms of displacement and asymmetry of the NLFs, nasal and circumoral regions were analyzed in the lateral, vertical and depth planes; as well as movement of the commissure and NLFs relative to the lower lip midline. Two‐samplettests were used to test for significant group differences.ResultsPatients NLFs had less mean displacement, greater mean asymmetry and uncoordinated movements compared with the controls. For both groups during smiling, the NLF and commissure landmarks had approximately similar magnitudes of displacement (control range = 11‐14mm; patient range = 7‐10mm).ConclusionNLF dynamics during smiling were as significant as oral commissure excursion. Thus, an immobile NLF is an unnatural feature of facial animations. Surgical treatments that address impaired NFL movements must be considered to create a more natural surgical outcome especially during smiling.
