The great auricular nerve (GAN) is a superficial branch of the cervical plexus that innervates parts of the mandible, auricle, and earlobe. Over the past 30 years, the GAN has become the nerve graft donor of choice for many surgeons for reconstructing injured facial nerves. In this review, we discuss the anatomy and function of the GAN, while focusing on surgical landmarks and the characteristics that make it a suitable nerve graft donor. In addition, we present and summarize published case reports on use of the GAN for grafting. We hope that this review will provide surgeons with an up-to-date and concise reference.

耳大神经移植的全面回顾

耳大神经 (GAN) 是颈丛的浅支，支配下颌骨、耳廓和耳垂的一部分。在过去的 30 年里，GAN 已成为许多外科医生重建受伤面神经的首选神经移植供体。在这篇综述中，我们讨论了 GAN 的解剖结构和功能，同时重点关注手术标志和使其成为合适的神经移植供体的特征。此外，我们介绍并总结了有关使用 GAN 进行嫁接的已发表案例报告。我们希望这篇综述能为外科医生提供最新和简洁的参考。
