Abstract:
A technique using vascularized pericranium to close dural defects after anterior clinoid and/or optic canal roof removal is described. This approach is simple, inexpensive, and uses autologous tissue. This method has provided satisfactory dural closure and has avoided cerebrospinal fluid leaks or extradural accumulation of cerebrospinal fluid.
