The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

3.1K
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...

Muscles for Facial Expressions01:14

Muscles for Facial Expressions

4.5K
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...

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

490
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Area of Science:

  • Plastic Surgery
  • Aging Research
  • Facial Anatomy

Background:

  • Facial aging involves both volume loss and descent, with their relative contributions unclear.
  • Understanding these processes is crucial for effective rejuvenation strategies.

Purpose of the Study:

  • To quantify the three-dimensional effects of gravity on the midface.
  • To compare these effects in younger and older patient groups.
  • To differentiate between volume loss and tissue descent in facial aging.

Main Methods:

  • Prospective study of 53 female patients without prior cosmetic treatments.
  • Three-dimensional photography captured in supine and sitting positions.
  • Analysis of volume shifts and structural displacements in 3D.

Main Results:

  • Shifting from sitting to supine position caused significant displacement of facial landmarks.
  • The brow tail elevated, tear troughs filled, and jowls diminished.
  • Volumetric analysis showed increases in the infraorbital, tear trough, and malar regions.

Conclusions:

  • Facial aging in this cohort was predominantly due to tissue descent.
  • Reversing gravitational effects restores youthful facial subunit positions and volume.
  • Fat redistribution via gravity reversal approximates results of direct volume transfer procedures.
