Summary
Forehead shape, influenced by the frontal bone, shows significant gender differences in angles and projection. These findings are crucial for aesthetic and reconstructive forehead surgeries.
Area of Science:
- Anatomy
- Anthropometry
- Medical Imaging
Background:
- The frontal bone dictates forehead shape, impacting both health and aesthetics.
- Computed tomography (CT) is utilized to assess frontal bone morphology.
Purpose of the Study:
- To evaluate frontal bone morphology across different age groups and genders.
- To analyze variations in frontal bone angles and thickness.
Main Methods:
- A cross-sectional study analyzed CT scans of 220 patients across three age groups.
- Measurements included upper and lower frontal slopes (UFS, LFS) relative to the Sella-Nasion (SN) line, and frontal thickness at various angles.
- Statistical analysis was performed using R software with a significance level of p < 0.05.
Main Results:
- Significant gender-based differences were observed in UFS and LFS (p < 0.001).
- Males exhibited steeper frontal slopes, indicating greater posterior inclination compared to females.
- Older males showed a significant increase in contour nasion (C-N) distance and frontal projection (p < 0.05).
Conclusions:
- Gender-specific variations in frontal bone structure are significant.
- These findings are essential for planning forehead cosmetic and reconstructive procedures.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

01:14Cranial Bones: Superior and Posterior View
2.0K
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
2.0K
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
6.3K
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...
