Abstract

|
Substantial progress has been made in peripheral nerve surgery, owing to the advances in pathophysiological understanding, microsurgical techniques and the improvement of synthetic materials. Despite this, large gaps caused by trauma, tumor resection and congenital deformities show unsatisfactory results. While primary direct end-to-end tension-free nerve repair remains as the gold standard for surgical treatment, an autologous nerve graft is recommended for nerve gaps greater than 2 to 3 cm. Studies cite remarkable clinical reports with decellularized nerve allografts after overcoming the previous immune suppression and cost issues with allograft nerve transfers. New light is being shed regarding synthetic nerve conduits that combines various cytokines and growth factors. Stem cell studies applying biomolecular and biological engineering technologies also show good results. Despite this, further assessment are required for clinical application because these results are based primarily on animal studies.
