Background
Thoracoscopic sympathectomy is a useful therapeutic option for palmar hyperhidrosis. Surgeons differ in the level of the sympathetic chain ablated. This study aimed to compare the blockade of the T2 with levels T2 and T3 to verify the effectiveness of different ablation levels in relieving hyperhidrosis symptoms.
Methods
For patients undergoing bilateral thoracoscopic sympathectomy for palmar hyperhidrosis, T2–T3 ablation is performed bilaterally. In our series, 25 consecutive patients were blindly randomized to undergo unilateral T2 and T3 ablation followed by contralateral ablation of level T2 only. The patients were followed up and analyzed for comparison of symptoms bilaterally, compensatory hyperhidrosis, and levels of satisfaction postoperatively.
Results
The study group consisted of 25 patients with a male:female ratio of 3:2 and a mean age of 32 years (range, 19–50 years). The mean operative time was 35 min. The patients were followed up for a mean period of 23 months (range, 2–65 months). All 25 patients confirmed that their palmar sweating resolved postoperatively, with both palms equally dry. Of the 25 patients, 20 (80%) complained of compensatory hyperhidrosis, which also was bilaterally symmetric. The areas involved were trunk (80%), lower limbs (32%), and armpits (12%). Overall, 80% of the patients were very satisfied with the procedure. The remaining 20% experienced mild to moderate compensatory hyperhidrosis, which did not seem to affect their lifestyle.
Conclusion
The findings show that T2 ablation in thoracoscopic sympathectomy for palmar hyperhidrosis is as effective as T2–T3 ablation in terms of symptomatic relief, recurrence, compensatory hyperhidrosis, and patient satisfaction.
