High reactive-level laser treatment (HLLT) uses lasers for tissue destruction and welding, while low reactive-level laser therapy (LLLT) promotes healing and pain relief. Both have applications in plastic and reconstructive surgery.

Area of Science:

  • Medical applications of laser technology.
  • Biomedical engineering.
  • Photomedicine.

Background:

  • Lasers have been used in medicine since the 1960s, expanding from ophthalmology and dermatology to plastic and reconstructive surgery (PRS).
  • Two primary modes of laser application exist: high reactive-level laser treatment (HLLT) for tissue destruction and low reactive-level laser therapy (LLLT) for therapeutic effects.

Purpose of the Study:

  • To differentiate and compare high reactive-level laser treatment (HLLT) and low reactive-level laser therapy (LLLT).
  • To discuss the applications of both HLLT and LLLT within plastic and reconstructive surgery (PRS).

Main Methods:

  • HLLT involves using laser energy to selectively vaporize, incise, ablate, coagulate, and denature proteins in target tissues, enabling procedures like laser tissue welding.

  • LLLT involves non-destructive laser application, resulting in minimal or no temperature rise and no immediate irreversible changes to tissue architecture, activating cellular processes.

    • Main Results:

    • HLLT applications include surgical procedures like excision and tissue welding.
    • LLLT applications encompass pain attenuation, accelerated wound healing, enhanced bone and tendon repair, neural restoration, hormonal normalization, immune modulation, and blood pressure regulation.

    Conclusions:

    • HLLT and LLLT represent distinct approaches to laser-mediated medical interventions.
    • Both HLLT and LLLT offer diverse and valuable applications in the field of plastic and reconstructive surgery.
