In the high radial nerve palsy caused by displaced humeral shaft fracture, radial nerve have to be explored in the fracture site. 5 cases of the ruptured radial nerve at the fracture site of the humerus from January 1993 through January 2005 were treated at first by open reduction and internal fixation with plates and screws fixation and then defective radial nerves were grafted with autogenous sural nerves by microsurgical epineurial and or perineurial neurorrhaphy. At average 30.4 months follow-up, 5 cases were recovered from motor and sensory deficit with solid bony union of the humerus shaft fracture. Authors have confirmed that ruptured radial nerve in the humerus shaft fracture grafted with autogenous sural nerve with microsurgical epineurial and or perineurial neurorrhaphy would be expected good motor and sensory recovery.

Peripheral nerve injuries in the oral and maxillofacial regions require nerve repairs for the recovery of sensory and/or motor functions. Primary indications for the peripheral nerve grafts are injuries or continuity defects due to trauma, pathologic conditions, ablation surgery, or other diseases, that cannot regain normal functions without surgical interventions, including microneurosurgery. For the autogenous nerve graft, sural nerve and greater auricular nerve are the most common donor nerves in the oral and maxillofacial regions. The sural nerve has been widely used for this purpose, due to the ease of harvest, available nerve graft up to 30 to 40 cm in length, high fascicular density, a width of 1.5 to 3.0 mm, which is similar to that of the trigeminal nerve, and minimal branching and donor sity morbidity. Many different surgical techniques have been designed for the sural nerve harvesting, such as a single longitudinal incision, multiple stair-step incisions, use of nerve extractor or tendon stripper, and endoscopic approach. For a better understanding of the sural nerve graft and in avoiding of uneventful complications during these procedures as an oral and maxillofacial surgeon, the related surgical anatomies with their harvesting tips are summarized in this review article.

Various nerves from many areas of body can be used as a donor of autogenous nerve graft in the microneurosurgical repair of the oral and maxillofacial region. In the grafting procedure of nerve repair, the best results will be achieved with a maximum approximation of fascicular surface at both the porximal and the distal stumps. Therefore, appropriate selection of donor nerve will bring out the best results. The sural nerve has been used as one of the most popular donor nerve in the microneurosurgical repair of the oral and maxillofacial region. The authors examined the fascicular characteristics of the human sural nerve microscopically and compare this results with our previous report of the greater auricular nerve and that of the inferior alveolar nerve.
