Electroacupuncture Therapy for Auricular Paresthesia

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.

Nerve block as neuropathic pain treatment for the great auricular nerve neuropathy: A case report

OBJECTIVE/BACKGROUND

The great auricular nerve (GAN) is a major sensory branch of the cervical plexus. Painful great auricular neuropathy causes pain circumscribed to the inferior preauricular region, the jaw angle, the ventral pinna, and the mastoid region.

METHODS

We present a 46-year-old woman experiencing facial pain in the bilateral preauricular and infra-auricular region, constant, of abrasive quality without any other associated symptomatology that is triggered or aggravated with cephalic movements, cervical turn, mandibular movement, and palpation on the affected area.

RESULTS

Symptomatic treatment with analgesics, anti-inflammatories, and neuropathic preventive medications was ineffective. However, nerve block anesthetic treatment resulted in complete pain remission.

CONCLUSION

Great auricular neuropathy is an uncommon cause of facial pain; our case report is the first bilateral occurrence reported to date. It should be suspected in patients with circumscribed shooting or lancinating paroxysmal pain in the territory of the GAN. It is characterized by the aggravation of pain with cervical movements and complete relief after anesthetic blockade.
