Background: C5 palsy (C5P) is a recognized potential postoperative complication of cervical spine surgery but has rarely been reported following an open esophageal diverticulectomy.
Methods: A 61-year-old underwent an open esophageal diverticulectomy for symptomatic Zencker's diverticulum.
Results: Postoperatively, she presented with right upper extremity weakness and sensory deficits consistent with a C5P that was later confirmed by electromyography.
Conclusion: The potential for C5P after esophageal diverticulectomy for symptomatic Zencker's diverticulum is rare. Postoperative recognition and appropriate management are critical to recovery.
Keywords: C5 palsy; Cervical spine; Cervical spondylosis; Esophageal diverticulum.
