Maxilla, Anterior View

Description

Anterior facial anatomy is presented with the maxilla forming the central midface, its alveolar process inferiorly supporting the maxillary teeth and its frontal process rising superiorly to meet the nasal bones. Medial to the infraorbital margin, the piriform aperture is framed by the maxillary crests and the anterior nasal spine, while the zygomatic process extends laterally toward the zygomatic bone at the infraorbital rim. The hard palate is implied posterior and inferior to the dental arcade, and the maxillary sinus occupies the body of the maxilla deep to the anterior wall. The nasal bone is highlighted in blue as a landmark at the bridge of the nose, immediately superior to the nasal aperture and articulating with the frontal bone and the frontal processes of the maxillae. Clinically, this relationship matters because nasal bone fractures rarely occur in isolation, and displacement can propagate into the nasomaxillary buttress and the frontal process of the maxilla, altering the contour of the midface and the airway at the nasal valve region. Surgeons reference the infraorbital margin, piriform aperture, and anterior nasal spine when assessing Le Fort fracture patterns, planning open reduction, or choosing fixation points along the maxillary buttresses. Dental occlusion tells the rest of the story. Faculty can place this image directly into head and neck anatomy teaching on the bony nose, maxilla, and hard palate, or into dental and OMFS curricula that cover the alveolar process, maxillary sinus proximity to the posterior teeth, and midface trauma landmarks. It also fits radiology and emergency medicine materials that correlate plain film or CT findings of nasal and anterior maxillary fractures with palpable surface landmarks.
