• maxillary artery • The sphenopalatine artery, a branch of the maxillary artery, 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. • After the greater palatine artery emerges from the greater palatine foramen it courses anteriorly and passes through the incisive foramen where it anastamoses with the posterior septal branch of the sphenopalatine artery to supply the anterior 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. Remember: 1. The ophthalmic artery is a branch of the internal carotid artery. 2. The maxillary artery and the superficial temporal artery are the terminal branches of the external carotid artery. 3. The pterygopalatine fossa is a cone-shaped paired depression deep to the infratemporal fossa. The pterygopalatine fossa is located between the pterygoid process and the maxillary tuberosity, close to the apex of the orbit. This fossa contains the maxillary artery and nerve and their branches arising here, including the infraorbital and sphenopalatine arteries, the maxillary division of the trigeminal nerve and branches, and the pterygopalatine ganglion. The pterygopalatine fossa communicates laterally with the infratemporal fossa through the pterygomaxillary fissure, medially with the nasal cavity through the sphenopalatine foramen, superiorly with the skull through the foramen rotundum, and anteriorly with the orbit through the inferior orbital fissure..

This is the basis for the topical intranasal administration of local anaesthetic (LA) towards the sphenopalatine foramen (SPF) which is hypothesized to diffuse a distance as short as 1 mm. Nonetheless, the SPG is located in the sphenopalatine fossa, encapsulated in connective tissue, surrounded by fat tissue and separated from the nasal cavity by a bony wall. The sphenopalatine fossa communicates with the nasal cavity through the SPF, which contains neurovascular structures packed with connective tissue and is covered by mucosa in the nasal cavity. Endoscopically the SPF does not appear open. It has hitherto not been demonstrated that LA reaches the SPG using this approach. Methods: Our group has previously identified the SPG on 3 T–MRI images merged with CT. This enabled us to measure the distance from the SPG to the nasal mucosa covering the SPF in 20 Caucasian subjects on both sides (n =40ganglia). This distance was measured by two physicians. Interobserver variability was evaluated using the intraclass correlation coefficient (ICC). Results: The mean distance from the SPG to the closest point of the nasal cavity directly over the mucosa covering the SPF was 6.77 mm (SD 1.75; range, 4.00–11.60).

The Facial Artery of the Dog
Oka jimas Folia Anat. Jpn., 57(1) : 55-78, May 1980 The Facial Artery of the Dog By MOTOTSUNA IRIFUNE Department of Anatomy, Osaka Dental University, Osaka (Director: Prof. Y. Ohta) (with one textfigure and thirty-one figures in five plates) -Received for Publication, November 10, 1979- Key words: Facial artery, Dog, Plastic injection, Floor of the mouth. Summary. The course, branching and distribution territories of the facial artery of the dog were studied by the acryl plastic injection method. In general, the facial artery was found to arise from the external carotid between the points of origin of the lingual and posterior auricular arteries. It ran anteriorly above the digastric muscle and gave rise to the styloglossal, the submandibular glandular and the ptery- goid branches. The artery continued anterolaterally giving off the digastric, the inferior masseteric and the cutaneous branches. It came to the face after sending off the submental artery, which passed anteromedially, giving off the digastric and mylohyoid branches, on the medial surface of the mandible, and gave rise to the sublingual artery. The gingival, the genioglossal and sublingual plical branches arose from the vessel, while the submental artery gave off the geniohyoid branches. Posterior to the mandibular symphysis, various communications termed the sublingual arterial loop, were formed between the submental and the sublingual of both sides. They could be grouped into ten types. In the face, the facial artery gave rise to the mandibular marginal, the anterior masseteric, the inferior labial and the buccal branches, as well as the branch to the superior, and turned to the superior labial artery.

Clinical Importance of the Middle Meningeal Artery

It directly attaches to the cranial bones (is incorporated into periosteal layer of dura mater), favors common injuries in course of head trauma. This review describes available data on the MMA considering its varability, or treats specific diseases or injuries where the course of MMA may have clinical impact. Key words: Middle meningeal artery (MMA), aneurysm of the middle meningeal artery, epidural he- matoma, anatomical variation of MMA. TOPOGRAPHY OF THE MIDDLE MENINGEAL ARTERY AND ITS BRANCHES Middle meningeal artery (MMA) [1] is most commonly the strongest branch of maxillary artery (from external carotid artery) [2]. It supplies blood to cranial dura mater, and through the numerous perforating branches it nourishes also periosteum of the inner aspect of cranial bones. It enters the middle cranial fossa through the foramen spinosum, and courses between the dura mater and the inner aspect of the vault of the skull. Next it divides into two terminal branches — frontal (anterior) which supplies blood to bones forming anterior cranial fossa and the anterior part of the middle cranial fossa; parietal branch (posterior), which runs more horizontally toward the back and supplies posterior part of the middle cranial fossa and supratentorial part of the posterior cranial fossa.

The mandibular landmarks about the facial artery and vein with multidetector computed tomography angiography (MDCTA): an anatomical and radiological morphometric study. Int. J. Morphol., 30(2):504-509, 2012. SUMMARY: The aim of this study was to investigate the course of the facial vessels according to several mandibular landmarks in living individuals using multidetector computed tomography angiography (MDCTA) to determine these related to sex and side. This study was conducted in the Radiology Department, Meram Faculty of Medicine, Necmettin Erbakan University (Konya, Turkey). In total, sixty faces from 30 specimens (15 males and 15 females) with symptoms and signs of vascular disease were evaluated for the facial vessels by MDCTA scan. The facial vessel parameters were measured according to the reference points (mandibular angle, mental protuberance, mental foramen and facial midline). The distance from the point at which the facial artery first appears in the lower margin of the mandible to the mandibular angle for right and left facial artery were observed as 3.53±0.66 cm and 3.31±0.73 cm in males, respectively. These distances were determined as 2.91±0.52 cm and 3.35±0.48 cm in females.
