OBJECTIVES: Hyperhidrosis is a the disorder of excessive sweating in certain regions of the body. It is usually treated with surgical sympathectomy. Radiofrequency therapy has been successfully used for sympatholysis. We tested the primary hypothesis that radiofrequency therapy is independently associated with decreased palmar hyperhidrosis and compared results for patients receiving this treatment with patients who underwent surgical sympathectomy. METHODS: We included all the patients undergoing treatment for hyperhidrosis between March 2010 and April 2012. Patients who underwent either surgical sympathectomy or radiofrequency ablation for palmar hyperhidrosis were included and analysed. The outcomes studied included complications, success of the procedure, patient satisfaction with their procedure and compensatory hyperhidrosis. RESULTS: There were 94 patients who met our criteria, of whom 46 (49%) had surgical sympathectomy and 48 (51%) had radiofrequency ablation performed. Radiofrequency had a success rate of 75% in treating hyperhidrosis, but this was found to be statistically lower than for surgical sympathectomy (95%; P < 0.01). The groups were similar regarding patient satisfaction (P = 0.26) and compensatory hyperhidrosis (P = 0.78). CONCLUSIONS: This is the first clinical study to evaluate the role of radiofrequency ablation and compare it with the surgical treatment option for palmar hyperhidrosis. Radiofrequency ablation significantly decreased hyperhidrosis, but it had a lower success rate than surgical sympathectomy.
