BACKGROUND: Thoracoscopic R4 sympathectomy has been recommended as a safe and effective surgical treatment procedure for primary palmar hyperhidrosis (PPH). However, approximately half of patients presented postoperative moist hands (PMH), and recurrence occurred individually. Therefore, more thorough long-term results should be evaluated. METHODS: Between January 2005 and December 2014, 506 consecutive patients with palmar hyperhidrosis treated with either R4 or R4+5 were retrospectively reviewed and followed-up. RESULTS: A total of 451 patients (89.1%) completed the follow-up with an average follow-up time of 30.7±25.4 months. Palmar sweating completely ceased in 178 patients (39.5%), whereas 215 (47.7%) achieved greater than 50% improvement, 43 (9.5%) achieved 20-50% improvement. Fifteen individuals (3.3%) experienced recurrence. The frequency of individuals achieving 100% improvement was significantly higher in the group R4+5 than in the group R4 (60.9% vs. 27.8%, respectively; P<0.001). A total of 321 patients (71.2%) showed compensatory hyperhidrosis with 290 (64.3%) and 29 (6.4%) experiencing mild or moderate types respectively. Two individuals (0.4%) suffered from severe type. The incidence of compensatory hyperhidrosis in the group R4+5 was significantly lower than the group R4 (63.8% vs. 73.7%, respectively; P=0.037). Regarding satisfaction, 345 (76.5%) and 83 (18.4%) patients were highly satisfied and partially satisfied with their surgical results, respectively. Six patients (1.3%) were dissatisfied, and 17 (3.8%) expressed regret for surgery. CONCLUSIONS: PMH occurred in over half of patients after R4 or R4+5 sympathectomy, but most of these patients were satisfied with the surgical results. R4+5 appears to be a better option for palmar hyperhidrosis with lower incidence of PMH and compensatory hyperhidrosis.
