Study the effect of the omental pedicle flap in sciatic nerve healing

Abstract

This study was done to observe the effect of omental pedicle flap in neuroraphies , sciatic nerve of 8 dogs which divided into equal two groups .The neuroraphy was performed, after that greater omentum was prepared by median laporotomy which later pass through a tunnel formed in the inguinal region by preserving its vascular supply and adapted then wrapped around the zone of neuroraphy in treated group.asciatic nerves of control group were severed and primary neuroraphy was done without applying omental flap. The histological examination of the biopsy specimens was done in the 60 th day for both groups. The amount of regenerated axons and intra neural connective tissue in two groups were examined. In the revasculorized neuroraphies by omental flap, there was a significant increase the number of regenerated nerve fibres and reduced perineural fibrosis when compared with control group.
