  • Abstract:
  • The spinal accessory nerve is entirely motor nerve. It is also called as Nerve of Willis named after Thomas Willis (Willis,1965). The nerve is derived from 6th branchial arch. This nerve is made up of 2 components: cranial and spinal root. We report a finding of the termination of spinal accessory nerve into the substance of sternocleidomastoid muscle without continuation in the posterior triangle. Radical neck dissection is the first line of treatment to diagnose and prevent cervical lymph metastasis in the patients of head and neck malignancy. Preoperative knowledge of such variation is crucial to identify the structures.
