Thoracoscopic sympathectomy effectively treats hyperhidrosis. A new technique involving complete T2 ganglion excision showed excellent short-term results, comparable to laser or monopolar coagulation, with long-term follow-up planned.

Area of Science:

  • Thoracic surgery
  • Minimally invasive procedures
  • Neuromodulation

Background:

  • Hyperhidrosis is a condition characterized by excessive sweating.
  • Thoracoscopic sympathectomy is a minimally invasive surgical option for hyperhidrosis treatment.
  • Current techniques involve T2 ganglion coagulation or laser injury, but superiority over complete excision is unproven.

Purpose of the Study:

  • To introduce and evaluate a novel thoracoscopic technique for complete T2 ganglion excision for palmar hyperhidrosis.
  • To compare the efficacy of complete thoracoscopic T2 ganglion excision with conventional coagulation techniques (laser or monopolar).

Main Methods:

  • A new thoracoscopic technique for complete T2 ganglion excision (and T3 for axillary sweating) was developed.
  • Sixteen patients underwent T2 ganglion excision on one side and coagulation on the contralateral side.

  • Patients were assessed at 1-year follow-up.

    • Main Results:

    • Excellent outcomes were observed in all patients.
    • No significant differences in treatment results were noted between the two techniques at the 1-year follow-up.
    • Both complete excision and coagulation provided effective symptom relief.

    Conclusions:

    • Thoracoscopic complete T2 ganglion excision is a viable and effective treatment for palmar hyperhidrosis.
    • The novel technique appears comparable to standard coagulation methods in the short term.
    • Long-term comparative data are needed to definitively establish the superiority of complete ganglion excision.
