Facial aging affects all layers, including the skeleton. This study analyzed skull changes in males and females across age groups to understand age-related bone resorption and its aesthetic impact.
Area of Science:
- Forensic Anthropology
- Anatomy
- Aesthetics
Background:
- Facial aging involves skin, fat, muscle, and skeletal changes.
- The primary affected layer dictates the visible signs of aging.
Purpose of the Study:
- Evaluate aging of the facial skeleton.
- Identify sexual differences in facial bone aging.
- Determine areas prone to bone resorption.
- Understand the aesthetic consequences for treatment.
Main Methods:
- Analyzed 241 skulls from the Institute of Forensic Medicine in Belo Horizonte, Brazil.
- Classified skulls by gender and age groups (<20, 20-50, >50 years).
- Assessed structural changes in the facial skeleton related to age and gender.
Main Results:
- Included 192 male and 49 female skulls.
- Detailed descriptions of sexual dimorphism in facial bone aging.
- Highlighted age-related peculiarities in skeletal resorption patterns.
Conclusions:
- Understanding the aging facial skeleton is crucial for aesthetic treatments.
- Considering all facial layers (skin, fat, muscle, bone) provides a holistic approach.
- Knowledge of skeletal aging aids in achieving natural-looking aesthetic outcomes for folds and shadows.

Sutures of the Skull
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...
Overview of the Skull
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...
Cranial Bones: Superior and Posterior View
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,...
Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Cranial Bones: Lateral View
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...
Introduction to the Skeletal System
Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...
