Area of Science:

  • Thoracic surgery
  • Minimally invasive procedures
  • Surgical innovation

Background:

  • Palmar hyperhidrosis is a condition causing excessive sweating in the hands.
  • Video-assisted thoracic sympathectomy (VATS) is a common treatment for hyperhidrosis.
  • Existing VATS techniques can leave noticeable scars.

Purpose of the Study:

  • To develop a less invasive surgical technique for thoracic sympathectomy.
  • To improve cosmetic outcomes for patients undergoing sympathectomy.

Main Methods:

  • A novel trocar design was utilized for the procedure.
  • A small skin incision (2.0-2.5 mm) was made in the midaxillary line.
  • Thoracic sympathectomy was performed using electrocautery at the T2-T3 rib level.

Main Results:

  • 180 patients with palmar hyperhidrosis were treated between October 1998 and March 1999.
  • No technique-related complications were reported.
  • Operative wounds healed almost completely within one week, leaving no visible scar.

Conclusions:

  • The developed technique offers scarless healing and enhanced patient cosmesis.
  • This approach represents a significant improvement over traditional sympathectomy methods.
  • Recurrence of hyperhidrosis was noted in some patients, requiring reapplication.
