The authors describe an oculofacial injury phenotype manifesting as a cleavage plane following the orbitomalar ligament in 5 cases. Across these cases, curvilinear wounds followed the course of the orbitomalar ligament, running clean planes through orbicularis oculi down to the infraorbital rim and arcus marginalis. One case involved bilateral orbitomalar ligaments, and 1 case involved the inferior canaliculus. Associated craniofacial injuries included orbital floor fracture, orbital hemorrhage, and zygomaticomaxillary complex fractures. Moderate-to-severe globe injuries were encountered, including hyphema, commotio retinae, retinal hemorrhages, cyclodialysis cleft, lens dislocation, and globe rupture. Wound closure included deep polyglactin sutures to recreate mid-facial support from the disrupted orbitomalar ligament; 1 case that did not receive deep, layered closure was associated with lower eyelid ectropion. These cases illustrate how orbitofacial ligaments may influence trauma phenotypes and inform subsequent repair.

01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
