    Purpose: Repairing of the duramater is one of the major factor that effects the mortality and morbidity of patients after neurosurgical approaches. The gold standard for repairing of duramater is watertight suture or duraplasty with autografts such as pericranium and/or temporal fascia. Sometimes edges of the dura mater generally are shrunken and the watertight suture of the dura becomes impossible especially in emergency conditions. In the present study, we aimed to determine the most effective artificial dural graft in experimental dural defect in rats. Materials and Methods: Twenty eights wistar albino rats weight ranging from 280-320 grams and equal numbers of male and female were used. The animals were divided into four groups. Control (n=7 Group-1), collagen matrix graft (n=7 Group-2), cellulose graft (n=7 Group-3) and teflon graft (n=7 Group-4). Rats were sacrificed after 30 days and their damaged dura were removed and sections were taken. All histological preparations examined using light microscope. Histological analysis focused on fibroblastic activation, new capillary formation, inflammatory reaction, foreign body reaction and capsule formation and results were compared. Results: While fibroblastic activation was observed most frequently in teflon graft group, new capillary formation, inflammatory reactions and capsule formation were most frequently seen in cellulose grafts group. Conclusion: This animal model for artificial dural grafts suggest that cellulose was the most effective dural substitute for repairing of defective dura.
