Posterior Septal Artery
The posterior septal artery is a branch of the sphenopalatine artery.[1] The posterior septal artery supplies blood to the respiratory region of the nasal septum that consists of the lower two-thirds of the nasal septum and most of the nasal floor.[1] The path of the posterior septal artery can be understood by splitting it into 3 segments. These segments are the pterygopalatine segment, the sphenoidal segment, and the septal segment.[1]
In most cases, the posterior septal artery divides from the sphenopalatine artery in the pterygopalatine fossa.[2] This part of the posterior septal artery is called the pterygopalatine segment.[1] The posterior septal artery passes through the sphenopalatine foramen to enter the nasal cavity.[2] To enter the posterior border of the nasal septum, the posterior septal artery travels along the anterior wall of the sphenoid sinus, passing by the sphenoid ostium and choana.[1] This part of the posterior septal artery is called the sphenoidal segment.[1] In this segment, the posterior septal artery becomes divided into a superior and inferior branch.[1] The superior and inferior branches of the posterior septal artery each split into the terminal septal branches that supply blood to the respiratory portion of the nasal septum.[1] This region of the posterior septal artery is named the septal segment.[1]
