BACKGROUND
Historically, dissection of the temporoparietal fascia immediately above the zygomatic arch has been avoided due to the risk of transection of the temporofrontal rami of the facial nerve.
METHODS
A total of 8 fresh cadaveric hemi-faces have been dissected to investigate the relationship of the temporofrontal rami of the facial nerve to the fascial layers in the temporal region.
RESULTS
The relationship of the temporofrontal rami of the facial nerve to the fascial layers in the temporal region is variable, with some deep rami coursing below the parotid-temporal fascia and other superficial rami reaching the temporoparietal fascia before entering the lateral edge of the orbicularis oculi.
CONCLUSIONS
Dissection of the temporoparietal fascia immediately above the zygomatic arch may place superficial branches of the temporofrontal rami at risk.
背景
从历史上看，由于存在面神经颞支横断的风险，一直避免在颧弓上方紧邻处解剖颞顶筋膜。
方法
共解剖了8个新鲜尸体半侧面部，以研究面神经颞支与颞区筋膜层的关系。
结果
面神经颞支与颞区筋膜层的关系各不相同，一些深支走行于腮腺颞筋膜下方，而其他浅支在进入眼轮匝肌外侧缘之前到达颞顶筋膜。
结论
在颧弓上方紧邻处解剖颞顶筋膜可能会使颞支的浅支面临风险。
