Botulinum toxin type a for great auricular neuralgia.

great auricular neuralgia is a rare disorder with only 18 cases described in the literature. Since it's a rare disorder, there are no evidence-based therapeutic recommendations but only case reports to guide physicians. We report a case of great auricular neuralgia treated with botulinum toxin type A subcutaneous injection with significant remission of pain. Botulinum toxin type A could be an effective and safe treatment in this setting; however, more studies are needed to confirm our results.
