Dural closure

Watertight dural closure is imperative after neurosurgical procedures because inadequately treated leakage of cerebrospinal fluid (CSF) can have serious consequences.


A variety of techniques for dural closure have been described, employing natural and artificial materials.

Watertight dural closure.

Watertight with additional muscle patch/ not watertight with small or large defect (>1 cm) remaining).

When such a task cannot be performed, dural substitute and other adjunctive measures can provide an effective barrier between the subarachnoid compartment and the extradural space.

A novel technique for dural reconstruction involves soft tissue grafts in the form of fibrous or fibromuscular flaps, which are placed on the dural defects to seal the gaps. These soft tissue grafts represent an appropriate scaffold for cell ingrowth and fibrosis, thus preventing CSF. In a pilot study, Velnar and Gradisink described the application of soft tissue grafts for dural reconstruction in 10 patients who underwent convexity meningioma surgery 1).
