“…NOE fractures result from high-energy blunt trauma and are the most difficult midfacial injuries to diagnose and manage (13)(14)(15)(16). Isolated NOE factures are uncommon; up to 60% of NOE fractures are associated with ZMC fractures, and 20% are associated with panfacial fractures (13).…”

“…Diagnosis of an NOE fracture requires identification of at least four of the five cardinal tracts to distinguish NOE fractures from other fracture patterns involving the maxilla and orbits. The anterior and posterior limbs of the medial canthal tendon form as a result of fusion of the eyelid tarsal plates and orbicularis oculi muscles and insert on the lacrimal crests bordering the lacrimal fossa (14,15,21) (Fig 7). Lateral displacement of the central fragment or medial canthal tendon disruption causes telecanthus, or blunting and shortening of the medial palpebral fissure.…”

“…Yellow dashed lines represent the ideal points of fixation for the NOE region, which are the inferior orbital rim (1), the frontomaxillary suture (2), the nasomaxillary buttress (3), and the frontonasal suture (4). fixation points (15). All grade 3 injuries require canthopexy (14,19).…”

“…All grade 3 injuries require canthopexy (14,19). Canthopexy involves securing wires to the medial canthal tendon, which are passed contralaterally though drill holes in the lacrimal bones and attached to stable frontal bone or hardware (15) (Fig 14).…”

“…Complications include late deformity, which is difficult to correct because of scar contracture (15,16,31). Canthopexy has an unavoidably high failure rate, leading to late telecanthus and globe malposition (16,22,32).…”

The advent of titanium hardware, which provides firm three-dimensional positional control, and the exquisite bone detail afforded by multidetector computed tomography (CT) have spurred the evolution of subunit-specific midfacial fracture management principles. The structural, diagnostic, and therapeutic complexity of the individual midfacial subunits, including the nose, the naso-orbito-ethmoidal region, the internal orbits, the zygomaticomaxillary complex, and the maxillary occlusion-bearing segment, are not adequately reflected in the Le Fort classification system, which provides only a general framework and has become less relevant in contemporary practice. The purpose of this article is to facilitate the involvement of radiologists in the delivery of individualized multidisciplinary care to adults who have sustained blunt trauma and have midfacial fractures by providing a clinically relevant review of the role of multidetector CT in the management of each midfacial subunit. Surgically relevant anatomic structures, search patterns, critical CT findings and their management implications, contemporary classification systems, and common posttraumatic and postoperative complications are emphasized.
