目的研究唇鼻部肌肉解剖、生物力学特征及其相互关系,为唇裂的完美修复奠定基础.方法对8例自然流产胎儿的唇鼻标本进行微型CT扫描,图片使用Mimics软件处理,获得了口轮匝肌和鼻肌的三维模型.结合局部解剖、组织切片制作了唇鼻肌肉三维组态模型,并与组织切片进行对比检验.进行唇鼻部相关肌肉生物力学与体表形变的三维有限元分析,并在263例隐性唇裂手术中应用验证.结果唇鼻部肌肉之间存在紧密联系,共同构成唇鼻肌肉复合体.各组张力线彼此交叉作用,构成唇鼻肌肉张力体系.据此设计了新的唇裂修复术式——唇鼻肌肉三维定向重建术,并在隐性唇裂的临床治疗中取得了满意效果.结论唇鼻肌肉在解剖学、组织学和生物力学之间存在紧密联系,构成了唇鼻肌肉复合体及其肌肉张力体系.唇裂修复应在恢复这一体系的基础上取得更加完善的效果.

Objective To investigate the nasolabial muscle anatomy and biomechanical characteristics.Methods Micro-computed tomography scan was performed in 8 cases of spontaneous abortion fetus lip nasal specimens to construct a three-dimensional model.The nasolabial muscle structure was analyzed using Mimics software.The three-dimensional configuration model of nasolabial muscle was established based on local anatomy and tissue section,and compared with tissue section.Three dimensional finite element analysis was performed on lip nasal muscle related biomechanics and surface deformationin Application verification was carried out in 263 cases of microform cleft lip surgery.Results There was close relationship between nasolabial muscle.The nasolabial muscle tension system was constituted,based on which a new cleft lip repair surgery was designed and satisfied results were achieved.Conclusions There is close relationship among nasolabial muscle in anatomy,histology and biomechanics.To obtain better effect,cleft lip repair should be performed on the basis of recovering muscle tension system.
