With the development of endonasal flaps, an understanding of the arterial anatomy of the nasal cavity has become increasingly important for clinicians. Despite this, there is a lack of current, accurate overviews in the literature. We have used both endoscopic and gross dissection of six fresh frozen cadaveric heads, alongside a literature review, to produce a comprehensive description of the anatomy. Four heads had their arterial systems injected with red latex. Three injected and two uninjected heads were dissected endoscopically, to provide a total of seven sides. The fourth injected head was hemisected for gross examination. The arterial systems were dissected and examined. The posterior septal artery was found to enter the nasal cavity from the sphenopalatine foramen in five sides. It bifurcated on the sphenoid rostrum in seven sides with a bifurcation lateral to the sphenoid ostium occurring in five sides and a medial bifurcation in two sides. The posterior septal artery supplied Kiesselbach's plexus on the nasal septum along with the greater palatine artery and septal branches of the superior labial and anterior ethmoidal arteries. The posterior lateral nasal artery arose from the sphenopalatine foramen in five sides to supply the lateral wall. The lateral wall branch of the anterior ethmoidal and the anterior lateral nasal artery anastomosed at the head of the inferior turbinate. These findings were mostly consistent with the current literature. We have produced a detailed and up-to-date description and diagram of the arterial supply to the nasal cavity, which may be of use to clinicians, anatomists and students.
随着鼻内瓣的发展，对于临床医生而言，了解鼻腔的动脉解剖结构变得愈发重要。尽管如此，目前文献中仍缺乏准确的综述。我们通过对六个新鲜冷冻尸体头部进行内镜检查和大体解剖，并结合文献回顾，对其解剖结构进行了全面描述。四个头部的动脉系统注射了红色乳胶。对三个注射了乳胶的头部和两个未注射的头部进行了内镜解剖，共七个侧面。对第四个注射了乳胶的头部进行了半切以进行大体检查。对动脉系统进行了解剖和检查。发现后鼻中隔动脉在五个侧面从蝶腭孔进入鼻腔。它在七个侧面于蝶骨嵴处分支，其中五个侧面分支位于蝶窦口外侧，两个侧面分支位于内侧。后鼻中隔动脉与腭大动脉、上唇动脉鼻中隔支及筛前动脉一起供应鼻中隔的克氏静脉丛。鼻后外侧动脉在五个侧面起自蝶腭孔，供应侧壁。筛前动脉的侧壁分支与鼻前外侧动脉在下鼻甲头部吻合。这些发现大多与当前文献一致。我们提供了一份关于鼻腔动脉供应的详细且最新的描述及示意图，可能对临床医生、解剖学家和学生有所帮助。
