Botulinum Toxin for the Treatment of Postmenopausal Craniofacial Hyperhidrosis.

Postmenopausal craniofacial hyperhidrosis describes a unique subset of primary focal hyperhidrosis in menopausal woman. This condition can be challenging to treat and may require multiple treatment modalities before patients express satisfaction with the results. Current treatment options for craniofacial hyperhidrosis include oral antimuscarinic agents, topical aluminum chloride powder, and botulinum toxin injections. We present the case of a 68-year-old female with craniofacial hyperhidrosis who did not respond to topical agents and did not tolerate an oral antimuscarinic agent. The patient was successfully treated with 100 units of onabotulinum toxin A along the forehead, frontal hairline, and periauricular scalp and reported significant improvement in symptoms and quality of life as a result. We review the literature describing targeted intradermal injection of botulinum neurotoxin as an alternative to medical therapy for craniofacial hyperhidrosis.
