“…A review of the literature has reported numerous cases of 6th and 11th cranial nerve anomalies; however, there remains only one other documentation of a 10th cranial nerve duplication in a 2019 case report. [1][2][3][4] The only other duplicate vagus nerve documentation discussed two nerves in an accessory setting unequal in size to each other. 5 In our case, the identical nerves needed to be differentiated for VNS placement.…”

Introduction Duplicate cranial nerves are fundamentally rare anatomical variants. Few case reports have documented cranial nerve duplication. One previous case report has reported a vagus nerve with a smaller secondary accessory nerve component. We present the first reported case of duplicate vagus nerves identical in size and thickness with otolaryngological diagnostic confirmation. Case Description A 25-year-old woman with seizures refractory to medical management decided to undergo placement of a vagus nerve stimulator. During carotid sheath microdissection, two parallel nerve tracts were identified. The two nerves were identical in size and width. Proximal dissection confirmed that the two nerves were independent of one another and neither was a branching segment. To confirm duplicate vagus nerves, otolaryngology was consulted intraoperatively and the duplicate nerves were verified. The vagus nerve stimulator was placed in typical fashion around the medial nerve. Conclusion This is the first reported case of duplicate vagus nerves identical in size and with confirmation by otolaryngology. The authors would like to highlight the operative management of the vagus nerve stimulator placement as well as integrity of the diagnostic conclusions based on size, further dissection, and specialist consultation.

Dual spinal accessory nerve: caution during neck dissection

2020

View full text Add to dashboard Cite

Preserving the spinal accessory nerve (SAN) is an important step in the modern-day neck dissection to avoid postoperative functional morbidity in patients. This goal can become technically difficult, especially, when rare anatomical variations are encountered. We present a case of dual SAN in a patient undergoing selective neck dissection for oral squamous cell carcinoma. Both SANs were preserved and patient had no shoulder dysfunction postoperatively. We take this opportunity to emphasise that meticulous dissection is the only proven way to preserve the nerve. And that surgeons should be aware of this anatomical variation. SAN should be subjected to minimal traction during neck dissection to avoid tension neuropraxia and long-term shoulder dysfunction.

The structural and functional organization of the accessory nerve remains a subject of discussion in view of its structural features. The data presented in the educational literature require revision and clarification. Currently, a large number of publications have accumulated reflecting various manifestations of the individual variability of the branches of the accessory nerve. This review summarizes modern data that will allow us to form a more complete picture of the functional anatomy and morphological variability of the accessory nerve.
