皱眉肌与降眉肌的临床解剖学研究

Clinical anatomical study of the corrugator and prcerus muscles

目的 为鼻额部除皱提供解剖学依据。方法 对 14例成人男性尸体头部标本 ,进行了大体及显微解剖。结果 皱眉肌分为横向型、斜向型、斜向分束型 ,以斜向型为主。该肌起点恒定 ,止点变化大 ,轮廓清楚 ,降眉肌起于鼻骨与鼻外侧软骨连接处以上 ,止于两眉内侧的水平线。结论 通过观察弄清了鼻额部深层的皱眉肌和降眉肌的形态及其与血管神经的关系。

Objective To provide the anatomical evidence for eliminating wrinkles of eyebrow by operation. Methods By goss and micro-dissection of 14 head specimens of adult man. Results Corrugator supercilii can be divided into three types, the transversal, the diagonal and the diagonal separable types in which the major one is the diagonal. The corrugator has a constant origin with varied insertions and its outline is distinct. Procerus muscles arise from the joining site of nasal bone and nasi cartilage and its insertion is at the level of both medial ends of eyebrow.Conclusion By observing the anatomical position and shape of corrugator and procerus, their relationship with nerve and vessels are elucidated.
