This chapter discusses maxillary and mandibular fractures, where malar-maxillary fractures represent approximately one‑third of all facial fractures. The maxilla forms the central buttress of the face, thus understanding its anatomy is a key in the evaluation and treatment of facial fractures. The incidence of facial fractures increases with age and peaks in adolescence. The horizontal buttresses of the midface are the superior orbital rim, the inferior orbital rim extending into the zygomatic arch, and the maxillary alveolus. The mandible provides the bony structure to the lower third of the face and contains the dentition that will allow for mastication. The condyle articulates with the middle cranial fossa at the glenoid fossa in the temporomandibular joint (TMJ). Maxillary and mandibular dentition is central in the management of maxillomandibular fractures. Fractures of the zygoma are classically labeled as tripod fractures in reference to the suture lines are zygomaticomaxillary (ZM), zygomaticotemporal (ZT), and zygomaticofrontal (ZF).
