    Summary

    Percutaneous Selective Radio-frequency Neuroablation (PSRN) offers a novel approach in plastic surgery to reduce wrinkles and improve facial balance by targeting facial nerve fibers. This technique shows promising results for aesthetic improvements and functional recovery.

    Area of Science:

    • Aesthetic Plastic Surgery
    • Neuromodulation
    • Medical Technology

    Background:

    • Facial wrinkles and asymmetry present common aesthetic concerns.
    • Existing treatments for facial dynamic modification have limitations.
    • Targeting specific facial nerve branches offers a potential solution for precise control.

    Observation:

    • Percutaneous Selective Radio-frequency Neuroablation (PSRN) utilizes radio-frequency energy delivered percutaneously.
    • An integrated electronic system facilitates 3D nerve localization via electrical stimulation and electrofulguration.
    • The technique targets terminal fibers of the facial nerve to modulate facial muscle activity.

    Findings:

    • PSRN effectively ameliorated forehead and frown wrinkles associated with muscular hyperactivity.

  • The procedure improved facial balance in patients with unilateral postrhytidectomy facial nerve paralysis.
  • Initial clinical experience with 21 patients demonstrated encouraging outcomes.

    • Implications:

    • PSRN presents a minimally invasive option for facial rejuvenation and functional restoration.
    • This technique may offer a new paradigm in managing dynamic facial asymmetries.
    • Further research into PSRN's long-term efficacy and broader applications is warranted.
