Maxilla of a Human Male as, Lateral View

Description

Viewed laterally, the maxilla is isolated in blue against the remaining skull, making its body and anterior surface easy to read in relation to the nasal bones and frontal process superiorly. Anteriorly and inferiorly, the alveolar process houses the maxillary teeth and continues posteriorly toward the maxillary tuberosity, while the palatine process projects medially to form the hard palate and the floor of the nasal cavity. Superiorly, the maxilla contributes to the infraorbital margin and orbital floor, and laterally its zygomatic process extends toward the zygomatic bone, defining the anterior portion of the zygomaticomaxillary region. Lateral orientation clarifies how the maxilla frames the maxillary sinus (antrum of Highmore) within its body, a relationship that underpins common clinical patterns of odontogenic maxillary sinusitis when posterior maxillary molar roots approximate the sinus floor. The view also supports teaching of the infraorbital nerve course, with the infraorbital foramen positioned on the anterior maxillary surface below the orbit, a key landmark for regional anesthesia and a structure at risk in midface trauma such as zygomaticomaxillary complex fractures and Le Fort patterns. Good midface landmarks. Suture relationships, including the zygomaticomaxillary and nasomaxillary articulations, are readable without the clutter of a full facial soft tissue envelope. Dental anatomy courses and head and neck anatomy labs can use this plate to anchor discussions of the hard palate, upper jaw dentition, and the bony boundaries of the nasal cavity and orbit. It also fits well in oral and maxillofacial surgery, ENT, and radiology teaching materials when correlating clinical procedures, fracture classification, and CT anatomy of the maxillary sinus and infraorbital region.
