Background And Aim:
Cleidocranial dysplasia is a rare disorder of skeletal development that mainly promotes, among other malformations, inadequate development of clavicles and failure in cranial closure. In this affection, the role of neurosurgery in addressing cranial defects is rarely discussed.
Material And Methods:
We conducted an extensive review of the literature using the PubMed database, giving a greater focus to publications in the field of neurosurgery. Additionally, we report a case of a 2-year-old female child with cleidocranial dysplasia.
Results:
In our review, we encountered several cases of orthodontic implications but a few cases on cranial defect approach.
Conclusion:
The articles present literature that is unanimous on the recommendation of expectant conduct in children since the cranial block can occur spontaneously, even if the delayed form. In our approach, we opted for an expected strategy concerning the cranial defect, using a helmet made for brain protection. We also made the referral for multidisciplinary monitoring of pediatrics, neuropediatrics, ophthalmology, dentistry, and orthopedics.

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,...
01:08Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
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...

The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...
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...
