背景：Lore筋膜和耳阔韧带分别位于耳廓的前下方，是一个独立的筋膜结构。这些结构的命名和描述在文献中不一致。还有人担心，将颈阔肌悬吊缝线置入这些结构可能会损伤下面的面神经干。本研究的目的是阐明Lore筋膜和耳阔韧带的解剖及其与面神经干的关系。材料与方法：采用12侧新鲜尸体半侧面部标本，对Lore筋膜和耳阔韧带进行解剖学研究。这包括耳周筋膜层的解剖和识别这两个结构的面神经干的关系。结果：12侧侧面部均可见Lore筋膜和耳阔韧带。所有病例的结构在解剖学上都不同。在每种情况下记录面神经的关系，发现面神经干位于两个结构的最浅表部分至少2 cm深。结论：Lore筋膜和耳阔韧带是独立的，一致的可显示的结构。就面神经干的安全性而言，两者均适用于颈阔肌悬吊缝合，Lore韧带可作为腮腺切除术中面神经保留的指导。(C)2012年英国整形、重建和美容外科医生协会。由爱思唯尔有限公司出版。保留所有权利。
Background: Lore's fascia and the platysma-auricular ligament are discreet fascial structures anterior and inferior to the auricle respectively. The nomenclature and descriptions of these structures have been presented inconsistently in the literature. There is also concern that placement of platysma suspension sutures into these structures may risk damage to the underlying facial nerve trunk. The aim of this study was to clarify the anatomy of Lore's fascia and the platysma-auricular ligament, and their relationship to the facial nerve trunk.Materials & methods: A cadaveric study utilising twelve fresh cadaveric hemi-faces was under-taken, investigating the anatomy of Lore's fascia and the platysma-auricular ligament. This comprised dissection of the periauricular fascial layers and identification of the relationship of these two structures to the facial nerve trunk. A histological study of Lore's fascia was performed.Results: Lore's fascia and the platysma-auricular ligament were identified in all 12 hemi-faces. The structures were anatomically distinct in all cases. The relationship of the facial nerve was documented in each case, with the facial nerve trunk found to lie at least 2 cm deep to the most superficial parts of both structures. Lore's fascia was demonstrable with histology.Conclusions: Lore's fascia and the platysma-auricular ligament are separate and consistently demonstrable structures. Both are suitable for platysma suspension sutures in terms of facial nerve trunk safety, and Lore's ligament can be used as a guide to facial nerve preservation in parotidectomy.
