Abstract：The study of anti-protruding properties of dura and its substitutes is important to reconstnlction of skull defecfs. The parameters of anti-protruding properties of dura and its substitutes are introduced on the basis of constant creep solution of the dural deflection under the constant intracranial pressure. Dura and its Substitutes are arranged in order to the parameters: fresh human dura is the best anti-protruding material, lyophilized human dura is the best substitute, and artificial membrane of bovine cardiac valve, silicone rubber and terylene are unsuitable for use as anti-protruding material. The measurements showed that dura is isotropic approximately, which temporalis myofascia and pericranium are anisotropic.
Keywords：Dural Reconstruction, lyophilized dura, dura substitutes, anti-protruding properties.参考文献：
