Anatomical changes in the East Asian midface skeleton with aging
Folia Morphologica
|March 30, 2017
Summary
The canine fossa deepens with age, becoming more concave. This finding suggests the canine fossa angle is a useful indicator for assessing midface aging in the Asian population.
Area of Science:
- Anatomy
- Aging Research
- Anthropology
Background:
- Facial rejuvenation requires understanding midface skeleton aging.
- The canine fossa, a key maxillary bone feature, has not been studied in relation to aging.
- This study investigates canine fossa depression in the Asian midface skeleton.
Purpose of the Study:
- To evaluate the aging process of the Asian midface skeleton.
- To assess the canine fossa's role in midface aging.
- To determine if canine fossa morphology changes with age.
Main Methods:
- Three-dimensional (3D) reconstruction of computed tomography (CT) scans from 114 Koreans.
- Measurement of canine fossa, maxillary, and piriform angles on 3D models.
- Analysis of age-related changes in bony regions for males and females.
Main Results:
- The canine fossa angle significantly decreased with age in both sexes, indicating increased concavity.
- Maxillary and piriform angles showed no significant age-related changes in females.
- Aging affects canine fossa depth more prominently than other midface angles.
Conclusions:
- The canine fossa angle serves as an effective marker for anatomical changes in the midface with aging.
- Canine fossa morphology changes are indicative of midface aging.
- Further research can utilize canine fossa measurements for aging assessments.

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
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...

01:22Sutures of the Skull
13.7K
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...

01:29Bone Disorders
5.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:19The Effect of Aging on Tissues
4.0K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:29Bone Formation by Intramembranous Ossification
12.1K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

5.3K
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...
