Prediction of compensatory hyperhidrosis with botulinum toxin A and local anesthetic

Objective: Compensatory hyperhidrosis (CH) is one of the most problematic complications of sympathectomy, which occurs often and is hard to treat. A predictive procedure (PP) for CH can help patients experience compensatory sweating before sympathectomy to determine whether or not to perform sympathectomy. Our study aimed to evaluate the CH after the PP and sympathectomy in patients with primary palmar hyperhidrosis using multiple drugs. Methods: We reviewed 83 patients who underwent a PP between July 2009 and August 2013 with primary palmar hyperhidrosis. In group A, we used levobupivacaine (n = 39). In group B, we used botulinum toxin A plus ropivacaine for the PP in group B (n = 44). Results: The CH rate after the PP was 44 % (group A) and 25 % (group B), and after sympathectomy 80 % (group A) and 75 % (group B). The prediction value between the PP and the sympathectomy was statistically significant in group A (p < 0.05). The positive prediction rate was 73 % and the negative prediction rate was 27 % in group A. Conclusions: Local anesthetic alone has a better predictive value. From our finding, patients should be made aware that CH after sympathectomy is less severe in 73 % of cases than that experienced in the PP.
