Frontal Process Of The Maxilla, Lateral View

Description

Frontal process of the maxilla rises superiorly from the anterior maxillary body as a triangular plate, forming the anteromedial margin of the orbit and the lateral wall of the nasal aperture in this lateral skull perspective. Superiorly, its articulation approaches the frontal bone at the frontonasal region, while anteriorly it meets the nasal bone to contribute to the nasal bridge. Along its posterior border, the medial orbital rim is defined adjacent to the lacrimal bone and ethmoidal region, with the anterior lacrimal crest marking the boundary of the lacrimal fossa. Bone contours are the focus. Clinically, the frontal process is a frequent landmark in naso-orbito-ethmoid and midface trauma, where fracture lines can disrupt the medial orbital buttress, alter the position of the medial canthus, and narrow the nasolacrimal outflow pathway. The anterior lacrimal crest provides attachment for the medial palpebral ligament and frames the lacrimal sac area, so precise appreciation of this ridge helps when discussing dacryocystorhinostomy planning or interpreting CT findings of post-traumatic epiphora. A lateral view keeps the relationship between the nasal bridge, medial orbital rim, and maxillary buttressing in one frame, which is often where learners lose orientation. Use this illustration in head and neck anatomy teaching (osteology of the orbit and nasal skeleton), in oral and maxillofacial surgery or ENT courseware on midface fractures, and in ophthalmic plastics references that need the bony context for lacrimal drainage procedures. It also suits medical publishing figures that label the maxilla, frontal process, nasal bone, and orbital margin without crowding adjacent facial bones.
