Area of Science:

  • Plastic Surgery
  • Anatomy
  • Facial Rejuvenation

Background:

  • Facial aging leads to sagging of the chin and jowls.
  • The superficial musculoaponeurotic system (SMAS) plays a crucial role in facial structure.
  • Platysma muscle contributes to neck contour and aging.

Purpose of the Study:

  • To describe a surgical technique utilizing SMAS undermining to improve chin and neck appearance.
  • To evaluate the efficacy of this procedure for specific aging concerns.

Main Methods:

  • Anatomical knowledge was applied to guide the dissection.
  • Superficial musculoaponeurotic system undermining was performed, extending to platysma muscle insertions.
  • A specific pulling technique was applied to the SMAS-platysma complex on the face and neck.

Main Results:

  • The procedure was performed on 84 out of 148 patients.
  • Excellent aesthetic results were observed in the treated patients.
  • The technique effectively addressed drooping chin and lateral gravity bags.

Conclusions:

  • SMAS undermining to the platysma muscle insertions is an effective facial rejuvenation technique.
  • This method offers significant aesthetic improvement for patients with specific signs of aging.
  • The described surgical approach provides a valuable option for addressing chin and neck laxity.
