Abstract：Objective To explore the value of application of the collagen sponge artificial dura without suturing to big bone flap decompression after severe traumatic brain injury (TBI). Methods The clinical data of 108 patients with severe TBI who underwent big bone flap decompression were analyzed retrospectiely. Of these 108 patients, 54 received the repair of dura mater with collagen sponge artificial idura without suturing in the observed group and 54 with the routine artificial dura in the control group. The operating time for dural repair, rate of postoperative complications, time interval from hematoma clearance to cranioplasty, operative time for cranioplasty, intraoperative blood loss volume, rate of dural damage and GOS scores 6 months after the operation were analyzed in the two groups. Results There were insignificant differences in the rate of postoperative complications (1.85%vs 7.41%) and GOS score 6 months after the operation between both the groups (P>0.05). There were significant differences in the operating time for dura repair [those in the observed and control group were (5.23 ± 1.25) min and (12.58 ± 2.65) min respectively], time interval from hematoma clearance to cranioplasty [those in the observed and control groups were (115.78 ± 21.56) days and (217.64 ± 34.32) days respectively], operative time for cranioplast [those in the observed and control groups were (73.25 ± 7.62) min and (98.63 ± 11.58) min respectively], intraoperative blood loss volume [those in the observed and control groups were (66.45±18.52) ml and (101.34±21.78) ml respectively], rate of damage to dura mater [those in the observed and control groups were 4% and 14.29% respectively) between both the groups (P<0.05). Conclusions The collagen sponge artificial dura without suturing is similar to the routine artificial dura with tightly suturing in the repair effect on the dura mater in the patients with severe TBI undergoing the big bone flap decompression, but the former can reduced dural perpair and cranioplasty time and intraoperative blood loss volume compared to the latter. Therefore collagen sponge artificial dura without suturing is of value to spreading use clinically.
