Hypothesis/Objectives: We tested the effectiveness of a temperature‐controlled CO 2 laser soldering system on a porcine model for dural defect reconstruction using a fascial patch. Methods: A dural patch was excised and then reconstructed with fascia by a CO 2 laser system in vitro in 27 animals and in vivo in five animals. Results: After dural reconstruction, the average burst pressure of the soldered patch in vitro, as measured by a custom‐made pressure detector, was 258.5 cm H 2 O. All five pigs in the in vivo group showed no neurological complications or cerebrospinal fluid leak, and the underlying brain tissue showed no thermal injury. Conclusion: The CO 2 laser system created a watertight bond and did not cause thermal injury to the brain. The procedure is potentially faster than conventional repair, and wound healing may also be more rapid.
