Summary
This study analyzed modern human craniofacial form using 3D Procrustes superimposition and computed tomography (CT). Results show excellent measurement repeatability and subtle regional variations, with European crania differing slightly from African and American groups.
Area of Science:
- Anthropology
- Forensic Science
- Anatomy
Background:
- Craniofacial morphology analysis is crucial for understanding human evolution and variation.
- Geometric morphometrics offers advanced tools for quantifying complex shapes.
- Establishing reliable reference models for craniofacial form is essential for comparative studies.
Purpose of the Study:
- To analyze modern human craniofacial form using 3D Procrustes superimposition.
- To establish a reference model for craniofacial shape.
- To validate this model using computed tomography (CT) data.
Main Methods:
- Utilized 3D Procrustes superimposition on 136 specimens from five modern human regional groups.
- Recorded 33 craniofacial landmark coordinates using Microscribe and CT scans.
- Performed discriminant analysis to assess shape variability and establish a reference model.
Main Results:
- Demonstrated excellent repeatability (R = 0.99) between Microscribe and CT measurements.
- Found no major distinctiveness in overall craniofacial shape across groups.
- Discriminant function 1 identified European crania as distinct, influenced by facial width, length, upper face flatness, maxillary prognathism, and palate dimensions.
Conclusions:
- Confirmed high accuracy of CT scan measurements and the utility of geometric morphometrics for craniofacial analysis.
- Highlighted subtle regional craniofacial variations, particularly distinguishing European crania.
- Suggested invariant features in maxilla and palate width may relate to dental alignment and masticatory functional patterns.

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,...

01:08Overview 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...

01:27Cranial 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...

01:22Sutures of the Skull
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...

01:14Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
01:29Three-Dimensional Analysis of Strain
Three-dimensional strain analysis is crucial for understanding how materials deform under stress, particularly in elastic, homogeneous materials. This method employs principal stress axes to simplify complex stress states into more understandable forms. Subjected to stress, a small cubic element within a material either expands or contracts along these axes, transforming into a rectangular parallelepiped. This transformation effectively illustrates the material's deformation. The principal...
