To compare unilateral dominant-side video-assisted thoracoscopic sympathectomy (U-VATS) with bilateral procedures (B-VATS) in terms of efficacy and complications and to identify predictors of outcome after U-VATS. ⋯ U-VATS proved to be equally effective as B-VATS with less postoperative pain, shorter hospital stay, less frequent compensatory sweating, and better improvement of planter hyperhidrosis. The results suggest that patients with preoperative Hyperhidrosis Quality of Life Questionnaire scores >80 are better operated via B-VATS, whereas lower scores are indicated for U-VATS.
