Summary
T4 sympathectomy effectively treats palmar hyperhidrosis (PH) with a 100% success rate. This procedure significantly reduces compensatory hyperhidrosis (CH), a common side effect of T2 sympathectomy.
Area of Science:
- Thoracic Surgery
- Neurosurgery
- Dermatology
Background:
- Compensatory hyperhidrosis (CH) is a significant complication following T2 sympathectomy for palmar hyperhidrosis (PH).
- Minimizing CH while effectively treating PH is a clinical challenge.
Purpose of the Study:
- To assess the efficacy of T4 sympathectomy for palmar hyperhidrosis (PH).
- To evaluate the rate of compensatory hyperhidrosis (CH) after T4 sympathectomy.
- To compare CH rates with those of T2 sympathectomy.
Main Methods:
- Bilateral thoracoscopic T4 sympathectomy was performed on 84 patients with palmar hyperhidrosis (PH).
- Patients were followed up for 18-42 months via clinic visits and telephone questionnaires.
- Outcomes recorded included success, regret, CH, recurrence, and complications.
Main Results:
- 100% success rate in eliminating excessive hand sweating.
- Only two patients (2.4%) experienced mild, non-disabling CH.
- No recurrence or patient regret was reported; four patients had minimal pneumothorax.
Conclusions:
- T4 sympathectomy is a highly effective treatment for palmar hyperhidrosis (PH).
- This approach demonstrates a remarkably low rate of compensatory hyperhidrosis (CH).
- T4 sympathectomy offers a superior safety profile regarding CH compared to T2 procedures.
