了解面神经颞支走行的位置及其颞部颧弓处与各解剖层次的相互关系,为神经外科手术中保护面神经颞支提供解剖依据是我们的研究目的.1 材料与方法30具男性新鲜尸体的头颅,在额部近中线发际内作切口,切开头皮延伸至额顶转向颞部,下行至耳屏前延伸到下颌角:分离出(1)帽状腱膜(该层再往下延伸为皮下组织,颞部为浅筋膜).(2)颞筋膜浅层、深层及筋膜间脂肪垫.(3)颞肌及其深部的骨膜.在分离上述各层次的同时在手术显微镜下解剖出面神经颞支(及其分枝),观察这些分支在各层次间走行情况及其与设立的参照线(耳屏及外吡间的连线)的数据,而后进行统计学处理.2 结果2.1 面神经颞支多位于帽状腱膜(浅筋膜)层,颞浅动
To understand the location of the temporal branch of the facial nerve and the relationship between its temporal zygomatic arch and each anatomical level for the neurosurgical operation to provide anatomical basis for the protection of the temporal branch of the facial nerve is our research purpose.Materials and Methods 30 male fresh cadaver Head, cut in the forehead near the midline hairline, cut the scalp to the top to the front of the temple, down to the front of the tragus extends to the mandibular angle: isolated (1) (2) Temporal fascia superficial, deep and inter-fascia fat pad. (3) Temporal muscle and its deep periosteum. In the separation of the above levels at the same time in the surgical microscope The temporal branches of the facial nerve (and their branches) were dissected to observe the movement of the branches at various levels and the data of the established reference line (the connection between the tragus and external ppi), and then statistically analyzed.2 Results 2.1 The temporal branch of the facial nerve mostly in the aponeurosis (superficial fascia) layer, superficial temporal motion
