BACKGROUND Several types of artificial nerve conduit have been used for bridging peripheral nerve gaps as an alternative to autologous nerves. However, their efficacy in repairing nerve injuries accompanied by surrounding tissue damage remains unclear. We fabricated a novel nerve conduit vascularized by superficial inferior epigastric (SIE) vessels and evaluated whether it could promote axonal ...

Introduction: Malignant tumors of the parotid gland account scarcely for 5% of all head and neck tumors. Most of these neoplasms have a high tendency for recurrence, local infiltration, perineural extension, and metastasis. Although uncommon, these malignant tumors require complex surgical treatment sometimes involving a total parotidectomy including a complete facial nerve resection. Severe fu...

The Canalis Sinuosus is a structure of the maxilla that allows passage anterosuperior alveolar nerve and has neurovascular activity. To visualize this structure, Conical Beam Computed Tomography (CBCT) best recommended. This article aimed to report case facial pain after insertion dental implant due compression Sinuosus. Thus, was removed, followed by bone graft. After that, stopped. In conclus...

IMPORTANCE Vocal fold immobility following injury to the recurrent laryngeal nerve (RLN) may lead to substantial morbidity. A reinnervation treatment strategy offers several theoretical benefits over static treatment options. This study evaluates the robustness of reinnervation of the larynx using a split-hypoglossal nerve graft in an animal model, with outcomes assessed by independent blinded ...

Conduction velocities and amplitudes of evoked responses were used in experimental models to compare reinnervation through nerve gaps sutured under tension or bridged with nerve grafts. The best results were obtained when end-to-end suture was done without tension. Regeneration through mildly stretched nerve repairs was equivalent to applying a properly tailored graft. Minimal axonal activity w...

Recently, we showed that Schwann cells transfer ribosomes to injured axons. Here, we demonstrate that Schwann cells transfer ribosomes to regenerating axons in vivo. For this, we used lentiviral vector-mediated expression of ribosomal protein L4 and eGFP to label ribosomes in Schwann cells. Two approaches were followed. First, we transduced Schwann cells in vivo in the distal trunk of the sciat...

Sixteen autogenous sural nerve grafts used for ulnar and median injuries in the forearm have been studied neurophysiologically up to two and a half years after operation. Motor and sensory nerve conduction studies revealed a slow but sustained improvement during the follow-up period. By two years, motor conduction velocity across the graft itself reached in most cases 40 to 85% of the conductio...
