Objective : The primary aim of this investigation was to explore the nature of dura mater biomechanics following the introduction of puncture defect(s). Methods : Twenty-eight dura mater specimens were collected during autopsy from the department of forensic medicine of the authors' institution. Specimens were divided randomly into one of four groups : group I (cranial dura mater; n=7), group II (cranial dura mater with one puncture defect; n=7); group III (cranial dura mater with two puncture defects; n=7), and group IV (cranial dura mater with three puncture defects; n=7). Results : The mean${\pm}$standard deviation tensile strengths of the dura mater were $8.35{\pm}3.16$, $8.22{\pm}3.32$, $7.13{\pm}1.77$, and $6.94{\pm}1.93MPa$ for groups I, II, III, and IV, respectively. There was no statistical difference between all groups. A single, two or more punctures of the dura mater using a 20-gauge Quincke needle did not affect cranial dura tensile strength. Conclusion : This biomechanical study may contribute to the future development of artificial dura mater substitutes and medical needles that have a lower negative impact on the biomechanical properties of dura mater.
