The great auricular nerve is a sensory branch of the cervical plexus, arising from the ventral rami of C2 and C3. It ascends vertically across the sternocleidomastoid muscle toward the parotid region, providing sensation to the skin over the parotid gland, the mastoid process, and both surfaces of the auricle. Its superficial course makes it susceptible to injury during surgical procedures in the neck or parotid region, which can result in numbness or tingling. Knowledge of its anatomical path is important for procedures such as lymph node biopsies, facelifts, and nerve blocks, as well as for avoiding iatrogenic injury while maintaining sensation in the auricular and adjacent regions.
