What Is the Maxillary Artery?
Department of the largest external carotid artery. Starting from the external carotid artery near the mandible neck. According to its location, it can be divided into 3 segments: the first segment is inside the mandible neck; the second segment is between the inner and outer wings of the wing; the third segment is inside the pterygopalatine fossa. Paragraphs 1, 3 have many branches.

Overview of the maxillary artery :
- This artery is mainly used to nourish the tissues in the maxillary area. If there is trauma or surgery there should be careful treatment of this artery and its branches.
Maxillary artery anatomy:
- The maxillary artery, also known as the internal maxillary artery, is one of the two terminal branches of the external carotid artery and is mainly distributed in the oral cavity, nasal cavity, teeth, masticatory muscles and dura mater. The maxillary artery starts at the deep side of the mandibular neck, moves forward and medial, and passes through the superficial plane of the lateral pterygoid muscle (more than 96%) from the infraorbital fissure into the orbit through the pterygopalatine fossa. Its branches are: deep ear artery and anterior tympanic artery, which originate from the beginning of the maxillary artery, line up and backward, and are distributed in the external auditory canal and tympanum. The inferior alveolar artery is sent forward and downward, enters the mandibular foramen, and exits the mandibular foramen through the mandibular canal. It is renamed the sacroiliac artery and is distributed on the lower lip and palate skin. The arteries branch into the mandibular teeth when in the tube; they branch to the mandibular hyoid muscle before entering the mandibular foramen. middle meningeal artery. It is the main artery of the dura mater. After it is issued, it passes through between the two ear and temporal nerves, penetrates the spine hole into the middle cranial fossa, and moves forward and outward along the sulcus. It is divided into the frontal and parietal branches on the inner side of the temporal scales. The forehead branch is thicker, first forwards and outwards, and then turns outwards and upwards, and about 70% of those who walk in the bone canal near the wing point (after the wing point account for 98.5%). The bones at the wing points are weak. If there is a fracture, the blood vessels are often torn, causing intracranial hemorrhage, and it must be handled promptly and carefully. The two branches of this artery finally branch to the dura mater of the frontal, parietal, and occipital regions. Meningococcal branches are more common in Chinese (about 87.7%). It originates from the middle meningeal artery or maxillary artery, enters the skull through the oval or spinous foramen, and is distributed in the trigeminal ganglia and its dura mater, as well as the pterygoid muscle and brevis muscle. Muscle branch, distributed in masseter muscle, temporal muscle, wing muscle and buccal muscle. The posterior maxillary artery passes through the maxillary wall and is distributed in the last 5 maxillary teeth and maxillary sinus. The descending iliac artery is divided into the zygomatic large and iliac small arteries descending through the pterygopalatine canal, which respectively penetrate the iliac large and iliac small holes, and are distributed in the iliac, gums, and iliac tonsils. The metatarsal sphenopalatine artery, through the sphenopalatine foramen to the nasal cavity, is divided into posterior lateral nasal artery and posterior nasal septum artery. The latter is distributed in the nasal septum and branches anteriorly and downwardly through the incisor to the iliac crest. The inferior orbital artery is a continuation of the main artery of the maxilla. It extends from the suborbital fissure into the orbit and passes through the infraorbital sulcus, suborbital canal, and suborbital foramen to the face. It is issued in the duct and the alveolar artery is distributed in the first three maxillary teeth and maxillary sinus.
- The surface signs of the middle meningeal artery have important clinical significance. The middle meningeal artery enters the skull through the spinous foramen at the upper edge of the midpoint of the zygomatic arch, and is divided into the frontal branch and the parietal branch 2cm above this point. The frontal branch first goes up to the wing point, then turns up and back to the midpoint between the root of the nose and the occipital protuberance; the top branch goes up and back to the herringbone point.
