The extended superficial musculoaponeurotic system (SMAS) facelift addresses facial aging signs like malar fat descent and jowls. This technique involves specific skin dissection and SMAS elevation for facial rejuvenation.
Area of Science:
- Plastic Surgery
- Facial Anatomy
- Aging Research
Background:
- Facial aging is characterized by malar fat descent and jowl formation.
- These changes lead to nasolabial folds, tear troughs, and obscured jawlines.
Purpose of the Study:
- To describe the concepts of the extended superficial musculoaponeurotic system (SMAS) facelift.
- To detail the extent of skin dissection and SMAS elevation in this procedure.
Main Methods:
- Review of the history and landmark papers of the SMAS facelift.
- Analysis of fresh cadaver dissections to illustrate anatomical considerations.
Main Results:
- The extended SMAS facelift aims to correct malar fat ptosis and jowl formation.
- Understanding the extent of dissection and elevation is crucial for effective rejuvenation.
Conclusions:
- The extended SMAS facelift offers a targeted approach to specific signs of facial aging.
- Cadaver dissections provide valuable insights into the anatomical basis of the procedure.

Non-invasive assessment of endothelial function in humans can be determined by the flow-mediated dilation technique. Although thousands of studies have used this technique, no study has performed this technique non-invasively in rats. The following article describes non-invasive measurement of flow-mediated dilation in the brachial and superficial femoral arteries of...
