Objectives: The purpose of this study was to compare immediate suture with delayed suture after nerve transected.
Materials and Methods: A group of 39 rats of Sprague-Dawley rats (250-300 g) were used in this study. 24 rats ha d a operation for facial nerve transected and delayed suture (1week later, 4 weeks later) was done. For controls, 12 rats transected facial nerve and sutured immediately. Then evaluated the recovery of immediate suture type, delayed suture type.
Results: In the feature of H&E, Luxol fast blue, histologic finding was similar in delayed suture group and immediate suture group.
Conclusion: Delayed suture group and immediate suture group had little difference. Delayed suture is acceptable for nerve injury due to implant installation in human cases.
