| Summary: | OBJECTIVE: Surgery for both palmar and axillar hyperhidrosis usually includes the interruption of the sympathetic chain in multiple levels. This study aimed to determine the long-term outcomes associated to video-assisted thoracic sympathotomy (VATS) of T2, T3 and T4 ganglia for these cases. METHODS: Analysis of the outcomes obtained from 36 patients regarding the rate of resolution of the symptoms and the compensatory sweating (CS). All subjects were followed-up for 36 months. RESULTS: Good outcomes were observed in 98.6% for palmar and 60% for axillary hyperhidrosis (p=0.0423), respectively. Of the subjects, 86% reported some postoperative episode of CS, however only 45% (p=0.0031) still noticed it at the end of the follow-up period. CONCLUSIONS: VATS is effective for the excessive palmar sweating, whereas it is fully efficient for only two thirds of the cases sustaining associated axillar hyperhidrosis. CS is expected as a rule following the proposed operative protocol, however it is usually self-limited.
