Introduction:
Notalgia paresthetica is a sensory mononeuropathy that affects dorsal segments T2 to T6. It can have a significant effect on quality of life. Numerous treatments have been used with variable results.
Material And Methods:
Five patients diagnosed with notalgia paresthetica were treated with intradermal botulinum toxin A. None had achieved relief of the pruritus with previous treatments.
Results:
Variable results were observed after the administration of intradermal botulinum toxin. Complete resolution of the pruritus was not achieved in any of the patients.
Conclusions:
Botulinum toxin A appears to be a safe therapeutic option for patients with notalgia paresthetica. However, data currently available come from small patient series, making it difficult to draw definitive conclusions regarding the true efficacy and long-term effects of this treatment.
