Aging causes changes in the superficial musculoaponeurotic system (SMAS)-platysma complex, affecting deep facial structures and skin. This study details age-related modifications and anatomical fixations within the aging face.

Area of Science:

  • Anatomy
  • Gerontology
  • Facial Plastic Surgery

Background:

  • Aging leads to loss of facial muscle tone and skin elasticity.
  • Understanding age-related changes in deep facial structures is crucial for effective rejuvenation procedures.

Purpose of the Study:

  • To investigate the anatomical modifications and behavior of the SMAS-platysma complex during aging.
  • To elucidate the impact of decreased tonicity and skin flaccidity on facial deep structures.

Main Methods:

  • Anatomical dissection of 18 hemifaces.
  • Detailed observation of the SMAS-platysma complex and associated facial structures.

Main Results:

  • The study identified specific modifications within the SMAS-platysma complex due to senescence.

  • Key ligamentary fixations were observed between the SMAS, parotid-masseteric fascia, zygomatic muscles, and platysma to the mandible periosteum.

    • Conclusions:

    • Age-induced changes in the SMAS-platysma complex significantly influence facial aesthetics.
    • Knowledge of these anatomical alterations aids in understanding facial aging and planning interventions.
