Surgical endoscopy
-
Upper thoracoscopic sympathectomy, obtained either by ablation or resection of the appropriate ganglia, is now the preferred treatment for primary palmar hyperhidrosis. Therefore, we undertook a review to compare the relative efficacy of these two techniques. ⋯ Resection yields superior results, yet the majority of surgeons ablate, probably because it is easier, requires a shorter operating time, leads to fewer cases of Horner's syndrome, and because resympathectomy eventually overcomes initial failure.
