Overview

• The blood supply of the mucosa of the nasal septum is derived mainly from the maxillary artery.
• The sphenopalatine artery, a branch of the maxillary, supplies most of the blood of the nasal mucosa.
• It enters by the sphenopalatine foramen and sends branches to the posterior regions of the lateral wall and to the nasal septum.
• The greater palatine artery, also a branch of the maxillary, passes through the incisive foramen to supply the nasal septum.
• The anterior and posterior ethmoidal arteries, branches of the ophthalmic artery, supply the anterosuperior part of the mucosa of the lateral wall of the nasal cavity and nasal septum.
• Three branches of the facial artery (superior labial, ascending palatine, and lateral nasal) also supply the anterior parts of the nasal mucosa.
