The alar fascia a portion or prevertebral fascia that may or may not be considered a distinct anatomical structure. [1] . When acknowledged, it is described as anterior to the prevertebral fascia. Superiorly, it extends to the base of the skull; inferiorly, it …

The alar fascia is commonly described as a complete fascial layer that lies coronally between the retropharyngeal and prevertebral fasciae and extends between the medial aspect of the carotid sheaths to form the anteromedial sleeve of the carotid sheath [1-3,6,7,12,13,22].

The alar fascia is a sheet of connective tissue running anterior to the prevertebral fascia, anterior to the vertebral bodies. There is a “danger” space between the alar fascia and the prevertebral fascia, where this potential space is closed in a healthy person.

2022年12月23日 · Results: Recent advancements have provided evidence that the alar fascia is a true fascial layer between the retropharyngeal and danger spaces within the deep cervical region. Although its composition, histological features, and borders remain topics of controversy, the alar fascia is comprised of dense connective tissue and may serve as a ...

The alar fascia is an independent and constant coronal fascial layer between the carotid sheaths. It contains neurovasculature and may limit the spread of retropharyngeal infections into the thorax as well as facilitate normal physiological functions of the cervical viscera.

2024年7月8日 · The alar fascia is a thin fibroareolar membrane separating the (anterior) true retropharyngeal space from the (posterior) danger space. It is the ventral component of the deep layer of the deep cervical fascia .

Grodinsky and Holyoke described a complete layer connecting the carotid sheath which lies between the visceral and prevertebral layer of the cervical fascia, and named it ‘alar fascia’ (Grodinsky and Holyoke, 1938). Recently, this fascia was confirmed by Gavid, who dissected both the alar fascia as well as the fascia prevertebralis (FPV).

日本九州医科大学国立医院耳鼻喉科系和神经外科的Noritaka Komune等通过尸头显微解剖，对颅底筋膜层次、网络关系及翼棘韧带、翼蝶韧带/肌肉解剖变异进行详细的分析，其结果发表于2019年2月的《World Neurosurgery》杂志。 ——摘自文章章节. 【Ref: Komune N, et al. World Neurosurg. 2019 Jun;126:e500-e509. doi: 10.1016/j.wneu.2019.02.078. Epub 2019 Feb 28.】 对于颅底外科医生来说，筋膜结构同神经血管一样重要，基于筋膜层的手术路径可以防止神经血 …

内侧部又称为茎突咽膜（stylopharyngeal fascia，SPF），其定义为：位于茎突、咽后外侧壁、颈内动脉管开口前缘之间三角形区域内的筋膜。 外侧部向后外侧，包饶茎突肌群、二腹肌后腹和胸锁乳突肌前部，向上于鼓骨鞘突、乳突前缘附着于颅底，向前与腮腺筋膜（见下文）相融合。 这里需简单插一下茎突肌群的解剖，三块肌肉分别是茎突舌骨肌（SHM，面神经支配）、茎突舌肌（SGM，舌下神经支配）和茎突咽肌（SPM，舌咽神经支配），空间排布、与二腹肌、舌咽 …

The alar fascia is a layer of the cervical neck fascia connected with the visceral fascia from C1 to T2 levels. The anatomical limits of this alar fascia and its relationships with the internal carotid artery are important in the surgical management and the …
