Efficacy and safety of high intensity focused ultrasound in the treatment of axillary hyperhidrosis : a randomized, double-blind, split-axillar, sham-controlled comparative study
Abstract:
There is currently no standard therapy in the treatment of Idiopathic axillary hyperhidrosis. Many treatments exist to treat hyperhidrosis. Aluminum compounds are antiperspirants used to treat hyperhidrosis. However, the treatment is not permanent and always relapse in one week. The side effects of the treatment are dermatitis, burning and itching. Currently, the US FDA has certified (Approved by US FDA), the use of botulinum toxin intradermal injection for the treatment of axillary hyperhidrosis. But the side effects of the treatment is pain due to multiple injection points. The treatment results are not permanent. Nowadays, has reported the results of treatment with high-intensity focused ultrasound (Ulthera) with the maximum energy of the machine was found to be successful in the United States. It never had a study about its efficacy on the other energy. The aim of study is to determine the efficacy and safety of high-intensity focused ultrasound in the treatment of Idiopathic Axillary Hyperhidrosis compare to the placebo for sweat reduction. The study enrolled 15 patients with moderate to severe bilateral axillary hyperhidrosis by HDSS. The lowest energy of Ulthera was performed using a 4MHz transducer with a focal depth of 4.5mm followed by a 7MHz transducer with a focal depth of 3mm while the energy level for sham treatments was set a 0 Joules. The results revealed 15 subjects completed on days 7, 30 and 90. Most subjects were female (12.3, 80.0%). The average age was 29.0 ± 8.5 years old. Scores from the pictures of the starch-iodine test were evaluated by 3 physicians who are not related to the study was found to reduce sweat production than placebo significantly. The treatment are satisfied and no negative side effects. The severity of the disease evaluated by HDSS decrease without experiencing any side effects.
As well as satisfying higher than placebo. The results of this study demonstrate the effectiveness and safety of high-intensity focused ultrasound to reduce underarm sweating.
