In order to preserve the frontotemporal branch of the facial nerve in frontotemporal and trans-zygomatic craniotomies, electromyographic responses from the facial muscles were recorded preoperatively. Incising the frontotemporal branch of the facial nerve could be avoided by identifying the crossing point of the frontotemporal branch of the facial nerve on the superior border of the zygomatic arch. The crossing points were investigated in 20 patients and in most cases they existed between 2 cm and 6 cm from the anterior border of the external auditory canal. Another important point to preserve the facial nerve is to conserve the layer in which the facial nerve is included. Therefore, the surgical anatomy in the region of the zygomatic arch and temporal area was reviewed in detail. This knowledge is crucial for neurosurgeons to dissect precisely in this region without causing postoperative facial palsy.
为了在额颞部和经颧弓开颅术中保留面神经额颞支，术前记录了面部肌肉的肌电反应。通过识别面神经额颞支在颧弓上缘的交叉点，可以避免切开面神经额颞支。对20例患者的交叉点进行了研究，在大多数情况下，它们位于距外耳道前缘2 cm至6 cm之间。保留面神经的另一个要点是保留包含面神经的层次。因此，详细回顾了颧弓和颞区的手术解剖结构。这些知识对于神经外科医生在该区域进行精确解剖而不导致术后面瘫至关重要。
