The Efficacy and Safety of a Latest Dural Substitute

A Prospective, Multi-center, Randomized, Parallel-controlled Clinical Trial Evaluating the Efficacy and Safety of Lyoplant Onlay in Repairing Cerebral Dura Mater

This prospective, multi-center, randomized, parallel-controlled clinical trial was designed to evaluate the efficacy and safety of Lyoplant Onlay in repairing cerebral dura mater. DURAFORM was regarded as the control group. a total of 80 patients were randomized into experimental and control group (1:1).Data were collected on complications resulting in CSF leaks, surgical site infections, instrument performance parameterized other neurological complications within 30 days. Surgeons also provided data on the ease of use of the dural sealing techniques, as well as preparation and application times. The above-mentioned date were used to evaluate the efficacy and safety of Lyoplant Onlay .
