摘要
目的:描述外侧入路和内镜腹侧入路咽旁段颈内动脉的解剖路图,提出亚分段方案,系统全面地理解该段动脉解剖以及其与周围结构的毗邻关系.方法:对5例(共10侧)新鲜尸头标本分别进行外侧入路和内镜腹侧入路解剖对照,评估咽旁段颈内动脉解剖及毗邻关系.结果:自颈总动脉分叉到颈内动脉管后垂直部,顺血流方向,咽旁段颈内动脉穿行通过4种截然不同的解剖组织,据此,该段颈内动脉可以划分为神经段、肌肉段、筋膜段、骨段4个亚分段.每个亚分段的边界和毗邻的重要解剖结构被详细描述.结论:咽旁段颈内动脉的解剖路图描述和亚分段方案,为降低颈内动脉损伤风险,模块化开展经外侧和内镜腹侧入路咽旁间隙等颅底手术,提供了应用解剖学依据.
Abstract
Objective:To describe the road map of the lateral and endoscopic ventral approaches for the pha-ryngeal segment of the internal carotid artery,propose a sub-segmentation scheme,systematically and compre-hensively understand its anatomical details and relationships with the surrounding structures.Methods:Five fresh cadaveric head specimens(10 sides in total)were dissected through lateral and endoscopic ventral approaches to e-valuate the anatomical details of the parapharyngeal internal carotid artery and its relationship with the surrounding structures.Results:From the bifurcation of the common carotid artery to the vertical part of the internal carotid artery,alongside the direction of blood flow,the parapharyngeal internal carotid artery passes through four dis-tinct anatomical tissues.Based on this,the parapharyngeal internal carotid artery can be divided into four sub-seg-ments:nerve,muscle,fascia and osseous sub-segments.The boundaries and important adjacent structures of each segment are described in detail.Conclusion:The anatomical road map of the parapharyngeal internal carotid artery and the sub-segmentation scheme serving as a practical guide to navigate modular endoscopic skull base sur-gery of the parapharyngeal space while reduce the risk of internal carotid artery injury.
