Primary frontal hyperhidrosis successfully treated with low doses of botulinum toxin A as a useful alternative to surgical treatment

Abstract

Frontal hyperhidrosis appears to be a special and rare form of focal hyperhidrosis. These patients may suffer greatly from the condition so an efficient treatment is highly demanded. Surgical treatment may solve this problem permanently, but the possibility of serious complications and low satisfactory results makes it less advisable than in other types of hyperhidrosis where surgery has shown great benefits. We report a case of primary frontal hyperhidrosis in a young man who refused surgery and was treated with low doses of botulinum toxin type A injected into the forehead. The patient noted a high level of satisfaction, with the abolishment of sweating and a long effect that was maintained for up to 10 months without any complications. In conclusion, we consider that low doses of botulinum toxin A is a well tolerated, safe and very effective treatment for primary frontal hyperhidrosis and it should be offered as an alternative to patients who suffer from this disorder.
