Summary
This study used the Janus procedure to analyze skull vault shape asymmetry. Most skulls showed left-sided predominance in shape, indicating subtle developmental variations.
Area of Science:
- Craniometry
- Biomedical Engineering
- Anthropology
Context:
- Skull shape analysis is crucial for understanding human evolution and development.
- Quantifying cranial asymmetry provides insights into growth patterns and potential pathologies.
- Previous methods for asymmetry analysis lacked detailed quantitative metrics.
Purpose:
- To develop and apply a novel computational method for quantifying skull vault shape asymmetry.
- To differentiate between isometric and allometric components of asymmetry.
- To assess the direction and magnitude of allometric asymmetry in human skulls.
Summary:
- Vertical frontal C.A.T. sections from 8 skull vaults were analyzed using the Janus procedure, a subset of Shape Analytical Morphometry (SAM) software.
- The Janus procedure normalizes and standardizes cranial profiles, creating a composite curve to detect asymmetry.
- This pilot study analyzed 24 sections, identifying a predominance of left-sided asymmetry (20 instances) versus right-sided (4 instances), with asymmetry components categorized as isometric, allometric, or both.
Impact:
- Introduces a new quantitative approach for analyzing cranial asymmetry.
- Provides a method to dissect asymmetry into distinct developmental components.
- Highlights potential left-sided bias in skull vault morphology, warranting further investigation.

01:08Overview of the Skull
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
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...

01:14Cranial Bones: Superior and Posterior View
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,...

01:27Cranial Bones: Lateral View
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...
