Summary
Skull measurements can reliably identify sex, aiding forensic anthropology. A new formula using cranial measurements achieved 79.9% accuracy in sex determination.
Area of Science:
- Forensic Anthropology
- Craniometry
- Sex Identification
Background:
- The human skull's complex structure, comprising 22 bones divided into the neurocranium and splanchnocranium, is known to possess sexually dimorphic characteristics.
- Accurate sex identification is crucial in anthropological and forensic contexts.
Observation:
- This study evaluated specific cranial measurements: mastoid notch to incisive foramen (bilateral), mastoid notch to mastoid notch, and incisive foramen to basion.
- Measurements were taken from 200 adult skulls (100 male, 100 female) with known demographic data.
Findings:
- Statistical analysis, including logistic regression and discriminant function, revealed significant dimorphic variations in the evaluated cranial measurements.
- A predictive formula was developed, achieving 79.9% accuracy for sex identification based on these measurements.
Implications:
- The developed formula offers an efficient and practical method for sex determination in forensic and anthropological investigations.
- The potential for a computer program to facilitate this analysis is highlighted, enhancing its applicability.

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...

01:14Cranial 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...

01:22Sutures 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...
