Abstract

Background and objectives: The purposes of this study were to demonstrate that laser soldering is safe and effective for tissue bonding in dural reconstruction and to compare this new reconstruction technique to an established one. Study design: A temperature-controlled fiberoptic CO2 laser system or fibrin glue were used for in vitro dural defect reconstruction in two groups of pigs. The CO2 laser technique was also used for dural reconstruction in live pigs. Results: The burst pressure of the reconstructed dura by the laser system was significantly higher than that of fibrin glue (mean pressure 258.5 ± 117.3 cm H2O and 76.8 ± 47.2 cm H2O, respectively). There were no postoperative complications and no signs of thermal damage to the dura, fascia, or underlying tissue on histological analysis following the in vivo CO2 laser experiments. Conclusions: Temperature-controlled laser soldering is an effective technique for dural repair. It creates a strong tissue bonding with no thermal damage to the tissue. The burst pressure of the reconstructed dura done with laser soldering is significantly higher than that of fibrin glue.
