Insights
The interparietal bone (Os Incae) can occur with craniosynostosis. Its incidence and effects in these patients are not well-understood, warranting further investigation into its formation.
Area of Science:
- Anatomy
- Pediatric Radiology
- Craniofacial Surgery
Background:
- The interparietal bone (Os Incae) arises from a persistent mendosal suture, a recognized anatomical variant.
- This bone is documented in anatomical and radiological literature.
Observation:
- Eleven pediatric cases with craniosynostosis and an interparietal bone were identified.
- These cases were drawn from two major children's hospitals.
Findings:
- The precise incidence of the interparietal bone in craniosynostosis or craniofacial anomalies remains unknown.
- Established sequelae, such as bathrocephaly, associated with interparietal bone presence in this context are not recognized.
Implications:
- This study highlights a potential association between interparietal bone and craniosynostosis.
- Further research is needed to elucidate the incidence, mechanisms, and clinical significance of interparietal bones in pediatric craniofacial conditions.
Abstract:
The interparietal bone, Os Incae, is formed in a persistent mendosal suture. This suture is a normal variant in the human skull, well-known in anatomy and radiology textbooks. We report 11 children with craniosynostosis in the presence of an interparietal bone, five from Children's Hospital at Montefiore and six children from Children's Hospital Boston. The true incidence of an interparietal bone in patients with craniosynostosis or craniofacial anomalies is not known; nor are there recognized sequelae of an interparietal bone (bathrocephaly). Hypotheses regarding mechanisms that may contribute to the formation of an interparietal bone are discussed.

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,...
Cranial 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...
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...
