Dural reconstruction following resection of ventral and lateral spinal cord meningiomas: Fenestrated Durotomy with Oversized Graft technique

•This report describes the methodology for repairing substantial dural defects on the ventral or lateral aspect of the spinal cord subsequent to the resection of intradural extramedullary tumors, such as meningiomas.•This technique obviates the need for intricate dural sutures and exhibits considerable versatility in addressing various defect types.•This is the first manuscript to confirm dural canal enlargement via MRI following the implementation of an artificial dura mater.
