Resolution of Iatrogenic Spinal Accessory Neuropathy Following Delayed Surgical Intervention.

We present an interesting case of a 74-year-old female who presented with spinal accessory neuropathy following an ipsilateral right-sided carotid endarterectomy 6 months after the initial injury. Subsequent surgical exploration revealed a surgical clip that had been placed directly across the spinal accessory nerve. Clip removal and neurolysis was subsequently performed, leaving the nerve intact. After surgical intervention, she immediately demonstrated increased bilateral shoulder shrug motion and continues to improve her function with physical therapy. This case demonstrates a fascinating case of cranial nerve recovery after delayed intervention in the context of existing literature. Laryngoscope, 135:2073-2075, 2025.
