Is Sympathectomy at T4 Level Better Than at T3 Level for Treating Palmar Hyperhidrosis?

Abstract

VTS at either the T3 or T4 level provides an effective treatment for PH. VTS at the T4 level is associated with a less severe form of CH. Despite the occurrence of CH, patients' quality of life is significantly improved following VTS at the T3 or T4 levels. For this reason, the T4 resection can now be used as a treatment for PH.
