RESUMEN
Hyperhidrosis is a common disorder that may have a severe impact on quality of life. The aim of this study was to investigate the clinical effect of two novel botulinum toxins, Xeomin®, a type A botulinum toxin, and Neuro-bloc®, a type B botulinum toxin, in the treatment of axillary and palmar hyperhidrosis. A total of 84 patients, 58 with axillary and 26 with palmar hyperhidrosis, were included in this open study. Axillae were injected with 107 ± 22 U Xeomin® and palms were injected with 213 ± 19 U Xeomin® and 264 ± 60 U Neurobloc® over the thenar eminences to avoid muscle weakness. At follow-up 3 weeks post-treatment, all patients treated for axillary hyperhidrosis reported satisfaction in self-ranking, evaporation decreased > 40%, and Dermatology Life Quality Index (DLQI) score improved from 12.0 to 1.7 (p < 0.05). In the palmar group 95% were satisfied, evaporation decreased > 50% and DLQI score improved from 10.3 to 1.2 (p < 0.05). Only one patient in the palmar group experienced muscle weakness. In conclusion, Xeomin® has an excellent effect on axillary hyperhidrosis and in combination with Neurobloc® on palmar hyperhidrosis. Neurobloc® may be an option for use in the treatment of palmar hyperhidrosis in order to minimize muscular side-effects.

BACKGROUND: Treatment of palmar hyperhidrosis with botulinum toxin (BTX) requires effective anesthesia, but previous methods have not provided enough pain relief or have resulted in a prolonged impaired hand function. OBJECTIVE: This is a study of bilateral forearm intravenous regional anesthesia using prilocaine for BTX treatment of palmar hyperhidrosis. METHODS: In all, 166 patients (100 female and 66 male) were treated bilaterally with intracutaneous BTX type A injections using intravenous regional anesthesia with prilocaine (5 mg/mL). In a subgroup of patients, forearm nerves were studied with neurophysiologic methods and blood concentrations of prilocaine were measured. Pain evaluation with a visual analog scale was accompanied with a questionnaire about the treatment. RESULTS: In all, 95% of the patients answering the questionnaire (response rate 89%) were satisfied with the anesthetic effect. No serious adverse events occurred. There was a fast recovery of motor function (in median 6 minutes) and sensory function (in median 20 minutes). No subclinical signs of sensory nerve damage were found. LIMITATIONS: Recall and reporting bias are potential sources of limitations in this study. CONCLUSION: Bilateral forearm intravenous regional anesthesia provides an effective and well-tolerated anesthesia during BTX treatment of palmar hyperhidrosis.
