Area of Science:

  • Aesthetic Surgery
  • Dermatology
  • Laser Technology

Background:

  • Neck and jowl liposuction is a prevalent cosmetic surgical procedure.
  • This study details the author's experience with laser-assisted liposuction for neck and jowl rejuvenation.

Purpose of the Study:

  • To evaluate the efficacy of Nd:YAG laser-assisted liposuction for treating submental lipodystrophy.
  • To assess the histological effects and cosmetic outcomes of the procedure.

Main Methods:

  • Submental lipodystrophy was treated using an Nd:YAG laser (1,064 nm wavelength).
  • Parameters included 6-W power, 40-Hz frequency, 150-mJ energy, and 100-microsecond pulse width.
  • Histological analysis of fatty tissue samples was conducted on 82 subjects over 5 years.

Main Results:

  • Significant cosmetic improvement was observed in the submental area.
  • Histology showed adipocyte membrane rupture, collagen coagulation, and channel formation.
  • Coagulation of small blood vessels and adequate skin contraction improved the cervicofacial region.

Conclusions:

  • The Nd:YAG laser is an effective tool for treating localized lipodystrophy.
  • The laser facilitates cellular lysis and promotes collagen neoformation for enhanced results.
