Abstract

In this manuscript, we report an anatomic variation of the spinal accessory nerve for the first time in the literature. The spinal accessory nerve was exited from the skull base in duplicate, and these two branches merged in the anterior triangle of the neck and continued as a common branch in a 68-year-old male patient who underwent total laryngectomy and bilateral modified neck dissection.

Keywords: Anatomy, anatomic variations, cranial nerves, spinal accessory nerve
