Summary
Pneumatization of the posterior clinoid process (PCP) occurs in 8.9% of children and is linked to age, not gender. This anatomical data aids neurosurgeons in pediatric skull base mapping.
Area of Science:
- Skull Base Anatomy
- Pediatric Neurosurgery
- Radiology
Background:
- The posterior clinoid process (PCP) is a key anatomical landmark in the skull base.
- Understanding its pneumatization and topographic relationship to adjacent structures is crucial for surgical planning.
Purpose of the Study:
- To detail the pneumatization patterns and positional anatomy of the posterior clinoid process (PCP) in healthy children.
- To provide reference data for neurosurgical approaches to the anterior and middle cranial fossae.
Main Methods:
- Analysis of computed tomography (CT) scans from 180 pediatric patients (aged 1-18 years).
- Evaluation of PCP pneumatization and measurement of distances from PCP to key landmarks (e.g., foramen ovale, anterior clinoid process).
Main Results:
- PCP pneumatization was observed in 8.9% of sides, correlating significantly with pediatric age (p < 0.001).
- Distances to various foramina and processes generally increased with age, while PCP-ACP distance showed irregular changes.
- Fusion between PCP and anterior clinoid process (ACP) occurred in 3.10% of cases.
Conclusions:
- The posterior clinoid process (PCP) serves as a valuable reference point for pediatric skull base mapping due to its central location.
- The findings offer essential anatomical data for neurosurgeons performing procedures in the pediatric skull base.

01:27Cranial Bones: Lateral View
2.1K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
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
6.5K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
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
2.1K
The superior view of the cranium shows the frontal and paired parietal bones.
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,...
