MiraDry
Microwave-based medical device used to treat axillary hyperhydrosis
From Wikipedia, the free encyclopedia
miraDry is a microwave-based medical device developed by Miramar Labs which is used in the treatment of axillary hyperhidrosis.[1] It was approved by the US Food and Drug Administration (FDA) in 2011 and was also approved in Europe.[1] miraDry selectively destroys axillary sweat glands without affecting the superficial layers of the skin.[1] In addition to sweat glands, miraDry destroys hair follicles in the axillary region regardless of hair color.[1] It is about 72.5 to 90% effective[2] and sweat is reduced by about 82% on average.[3] It also reduces axillary hair by about 75%.[4] The effects of miraDry are noticeable almost immediately and are long-lasting or permanent.[1] A case of death due to miraDry caused by necrotizing fasciitis that was complicated by streptococcal toxic shock syndrome has been reported.[5][6]
