We have developed a dual-component artificial nerve graft comprising an outer microporous conduit of chitosan and internal oriented filaments of polyglycolic acid (PGA). The novel graft was used for bridging sciatic nerve across a 30-mm defect in six Beagle dogs, which were used as a chitosan/PGA graft group. The other Beagle dogs were divided into an autograft group (n = 6) as the positive con...

Objective- Adipose tissue is an appropriate source for isolation of cells with stem-cell–like properties.  In the present long-term study, the effects of the omental adipose-derived nucleated cells (OADNCs) fraction were compared to those of the undifferentiated cultured bone marrow stromal cells (BMSCs) on sciatic nerve regeneration. Design- Experimental in vivo study. Animals- Fift...

PURPOSE To evaluate three different kinds of neurorrhaphy of the peroneal nerve. METHODS Eigthy rats were divided into 5 groups. Control: nerve had no intervention. End-to-end (EE): nerve was cut and elongated with a nerve graft with two end-to-end neurorrhaphies. End-to-side (ES): nerve was cut and sutured to the graft with at the lateral side of the nerve. Side-to-end (SE): the nerve was cu...

BACKGROUND Since vein grafts have been used in the repair of nerve defects, studies regarding this procedure have accumulated, and after coming into clinical use, it was noticed that there is a problem of collapse in the vein graft. METHODS Forty Sprague-Dawley rats were used, divided into five groups. No surgical intervention was performed in the first group. The defect was created in the sc...

Smiling is an important aspect of emotional expression and social interaction, leaving facial palsy patients with impaired social functioning and decreased overall quality of life. Although there are several techniques available for facial reanimation, staged facial reanimation using donor nerve branches from the contralateral, functioning facial nerve connected to a cross-face nerve graft (CFN...
