OBJECTIVE: The objective of this study was to compare the histological regeneration characteristics of nerve fibers at the anastomosis lines performed by classic suture technique or a tissue adhesive (N-butyl-2-cyanoacrylate).
METHODS: The control group consisted of 7 rabbits. The 21 rabbits were randomly divided into 3 groups based on the harvesting week. In the study group following preparation of facial nerve bilaterally, a 0.5-cm segment of facial dorsal buccal nerve was resected, and the defect was repaired with a nerve graft, which was harvested from sural nerve of the same side by 8-0 nylon suture technique and by application of N-butyl-2-cyanoacrylate on the other side.
RESULTS: Electron microscopic examination at consecutive second, fourth, and sixth days (corresponding to 4th, 8th, and 12th week in human subjects) revealed increased nerve degeneration findings in N-butyl-2-cyanoacrylate group when compared with microsuture repair technique.
CONCLUSIONS: We conclude that N-butyl-2-cyanoacrylate is not an appropriate material for nerve anastomosis.
