Demonstration of the Nasal Septal Branches of the Sphenopalatine Artery by Use of a New Intravascular Injection Method

Abstract

We injected a new injection material into the external carotid artery using a new method, which led to the successful demonstration of the nasal septal branches of the sphenopalatine artery in human cadavers. The result shows the trunk of the artery divided into three main branches, the upper two of which run toward Little's area. We believe that the knowledge of septal branches, shown in a photograph, is very useful, not only for nasal treatment, but also for anatomic demonstration to students.
