Management of Primary Focal Hyperhidrosis

LY Chan and YM Tang

Primary focal hyperhidrosis is a common problem that can be socially embarrassing and occupationally disabling. Aluminium chloride hexahydrate is widely used as a first line treatment which is cheap and effective for mild cases. Tap water iontophoresis can be effective when patients fail or are intolerant to topical antiperspirant. Recently, botulinum toxin has been used successfully for patients with severe hyperhidrosis not responsive to conservative treatments. Improved techniques in cervical sympathectomy have made the procedure relatively simple and safe. Excision of axillary skin bearing sweat glands is a definitive treatment for axillary hyperhidrosis and/or bromhidrosis but the risks of haemorrhage, infection and contractural scarring preclude its wide use. The removal of axillary fat that contains the sweat glands by tumescent liposuction has therefore evolved into an effective and safe alternative treatment without the disadvantage associated with axillary skin excision. The various treatment modalities for primary focal hyperhidrosis are reviewed.
