摘要
目的;观察激光对颅神经再生情况的影响.探讨激光吻合颅神经的可能化 方法:将10只家猫的动眼神经在颅内段切断后,以CO_2(1.5W,光斑长0.5cm,宽0.3mm)激光原位吻合修复,术后观察瞳孔对光反射、神经纤维直径、通过率等指标.结果:14wk后术侧瞳孔对光反射功能恢复良好,神经组织学观察轴突再生情况良好,神经纤维通过率达83.47%,未见有害影响.结论:CO_2激光可作为修复颅神经的一种有效工具.
To study the possibility of the carbon dioxide-laser on severed cranial nerves repair. Methods:Unilateral oculomotor nerves within cranial cavity of ten cats were transected, and then reconstructed by liner style carbon dioxide laser at the local site. Results: After 14 weeks, the pupil of transected side recovered from amplifying due to denervation. histomorphological examinations revealed good axon regeneration, the rate of nerve fibers crossing the laser anastomosis area was 83. 47%, and no remarkble damages were found. Conclusion:The present results indicated that carbon dioxide laser could be used effectively in the microsurgical repair of cranial nerves.
