Abstract:
The majority of primary craniosynostosis cases are sporadic. Very few articles in the literature have described cases of primary craniosynostosis associated with neural tube defects (NTDs). This co-occurrence has been seen by most authors as just a coincidence. The authors report a clinical series of 4 patients of primary craniosynostosis associated with NTDs treated at their center. Among these 4 cases, 2 had lumbosacral myelomeningocele, 1 frontoethmoidal encephalocele and 1 had occipital encephalocele. Although the co-occurrence of craniosynostosis and NTD is said to be rare, there seems to exist a justified underlying explanation for the same. The NTD causes a decrease in intracranial pressure due to egress of cerebrospinal fluid in the malformed sac that results in a deficient cerebral impulse for cranial growth that might stimulate premature sutural fusion. Thus, all patients with NTDs should be thoroughly evaluated for this association and for possible surgical management.

Sutures 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...

Cranial 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,...
