Great Auricular Neuralgia: Case Series

Background/Objective The great auricular nerve (GAN) arises from C2‐C3 and provides innervation over the skin in the pre‐auricular region, jaw angle, posteroinferior pinna, and mastoid. Although damage to the GAN has been reported following trauma or procedures nearby this nerve course, neuralgia of this nerve is uncommon with knowledge based on a handful of case reports in literature. The objective of this study is to describe the presentation, treatment, and outcome of 13 cases of GAN neuralgia. Methods Case series . Retrospecive review of charts from 1994 to 2018 with diagnoses: “auricular neuralgia,” “auricular neuritis,” or “auricular neuropathy.” We included subjects with neuralgic pain within the distribution of the GAN, and excluded patients with atypical facial pain, GAN neuropathy, or unclear etiology. Results Of 79 charts, 13 patients met criteria (age at onset 11‐59; 11 women, 2 men). Pain was most often described as paroxysmal stabbing provoked by: turning the head (n = 7), touching the neck (n = 5), neck position during sleep (n = 2), jaw movement (n = 2), and other (n = 2). Seven patients received GAN blocks: all noted dramatic improvement in pain, including 3 who continued to receive serial blocks at our institution successfully for the next 2 to 5 years. Two patients successfully transitioned from GAN blocks to GAN stimulators. One patient with GAN lymphoma had resolution of pain following GAN resection. Conclusion GAN neuralgia should be considered in the differential for periauricular pain. GAN blocks or stimulators may be helpful for pain management.
