Growing fracture of the orbital roof
1Division of Neurosurgery, Security Forces Hospital, Riyadh, Saudi Arabia.
Background:
Growing fractures rarely arise in the skull base, and their pathogenesis and treatment are still debated.
Methods:
The clinical and radiologic findings of a growing fracture involving the orbital roof in a 5-year-old boy are presented and the relevant literature is reviewed.
Results:
The clinical picture of growing fracture of the orbital roof is dominated by ocular symptoms such as diplopia, eyelid swelling, and displaced eye globe. Computed tomography scan is excellent for demonstrating the bony defect in the orbital roof while magnetic resonance imaging is more sensitive in showing the intraorbital extension of the leptomeningeal cyst. Frontobasal brain injury seems to play an important role in the pathogenesis of the fracture growth. Craniotomy with direct repair of the dural and bone defects is the treatment of choice.
Conclusion:
Growing fracture of the orbital roof may complicate minor head injury and should be considered in the differentiated diagnosis in cases of persistent ocular symptoms.

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 procedure...
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,...
01:27Cranial 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...
