BACKGROUND
In our experience, the anterior carotid sheath forms an important plane of dissection when excising temporal bone region cancers. However, its anatomical composition, relationships, and radiological appearance remains unclear.
METHODS
Eight sides of cadaveric heads were dissected. Anatomical findings were correlated with a high-resolution baseline T1 MRI.
RESULTS
The anterior carotid sheath was formed by the tensor-vascular-styloid fascia, stylopharyngeal fascia, buccopharyngeal fascia (BPF), and longus capitis fascia (LCF), and appeared as a hypointense line on MRI. Not previously described, the glossopharyngeal nerve pierced the sheath 9.0 mm (SD 2.1 mm) below the skull base and traveled through its LCF and BPF layers to exit near the pharynx.
CONCLUSION
Multiple fascial layers formed the anterior carotid sheath at the skull base, and this was radiologically identifiable. Further studies are required to validate findings and investigate the role this fascial plane has in forming an effective barrier to spread of malignancy.
背景
根据我们的经验，在切除颞骨区域癌症时，颈动脉前鞘形成了一个重要的解剖平面。然而，其解剖结构、关系和影像学表现尚不清楚。
方法
对 8 侧尸体头颅进行解剖。将解剖学发现与高分辨率基线 T1 MRI 相关联。
结果
颈动脉前鞘由张量血管茎突筋膜、茎突咽筋膜、颊咽筋膜（BPF）和头长肌筋膜（LCF）形成，在 MRI 上呈低信号线。以前未描述的是，舌咽神经在颅底下方 9.0mm（标准差 2.1mm）处穿过鞘，并穿过其 LCF 和 BPF 层，在靠近咽的部位穿出。
结论
在颅底，多个筋膜层形成了颈动脉前鞘，这在影像学上是可识别的。需要进一步的研究来验证这些发现，并研究这个筋膜平面在形成恶性肿瘤扩散的有效屏障方面的作用。
