Maxillary Body, Lateral View

Description

Maxillary body (corpus maxillae) dominates the lateral midface in this image, with the zygomatic process projecting superolaterally toward its articulation with the zygomatic bone. Medially, the lateral wall of the nasal cavity and the margin of the piriform aperture define the boundary of the nasal opening, while the anterior surface of the maxilla forms the facial contour inferior to the orbit. The infraorbital region is identifiable along the superior aspect of the body, and the alveolar process extends inferiorly to support the maxillary dentition, transitioning posteriorly toward the maxillary tuberosity. Spatial relationships read cleanly from lateral to medial: zygomatic buttress laterally, maxillary body centrally, nasal cavity medially. Fracture patterns and surgical corridors in this area depend on knowing where the zygomaticomaxillary buttress, infraorbital margin, and anterior maxillary wall sit in relation to the nasal cavity and orbital floor, and that is exactly what this perspective clarifies within a single frame. Zygomaticomaxillary complex injuries and Le Fort fracture lines traverse the maxillary body near the infraorbital foramen and maxillary sinus walls, putting the infraorbital nerve at risk and altering midfacial projection. A tight anatomical landmark set. Common use includes teaching midfacial osteology in dental and medical gross anatomy, illustrating the maxilla in orthodontic and implant planning discussions, and supporting maxillofacial surgery or ENT publications that reference Caldwell-Luc access, sinus wall anatomy, or infraorbital nerve blocks by surface landmarks.
