Summary
Isolated spinal accessory nerve injury can occur after neck surgery. This case report details an unusual instance following suboccipital decompression for Arnold-Chiari malformation, a previously unreported association.
Area of Science:
- Neurosurgery
- Neurology
- Anatomy
Background:
- Spinal accessory nerve (SAN) injury is a known complication of posterior neck surgeries.
- Procedures like lymph node biopsy and carotid endarterectomy commonly lead to SAN injury.
Observation:
- This report details a case of isolated SAN injury.
- The injury was localized proximal to the sternocleidomastoid muscle innervation.
- The complication occurred after suboccipital decompression for an Arnold-Chiari malformation.
Findings:
- The study presents a novel association between suboccipital decompression and isolated spinal accessory nerve injury.
- This specific surgical context for SAN injury has not been previously documented in medical literature.
Implications:
- Highlights the importance of considering SAN injury in a broader range of neurosurgical procedures.
- May prompt surgeons to re-evaluate surgical techniques and nerve monitoring during posterior fossa operations.
- Contributes to a more comprehensive understanding of iatrogenic nerve injuries in neurosurgery.
