Cortical reintegration after facial allotransplantation.

Neural plasticity of the brain or its ability to reorganize following injury has likely coincided with the successful clinical correction of severe deformity by facial transplantation since 2005. In this study, we present the cortical reintegration outcomes following syngeneic hemifacial vascularized composite allograft (VCA) in a small animal model. Specifically, changes in the topographic organization and unit response properties of the rodent whisker-barrel somatosensory system were assessed following hemifacial VCA.

Response properties of whisker-associated primary afferent neurons following infraorbital nerve transection with microsurgical repair in adult rats.

The rodent whisker/trigeminal system, characterized by high spatial and temporal resolution, provides an experimental model for developing new therapies for improving sensory functions of damaged peripheral nerves. Here, we use controlled whisker stimulation and single-unit recordings of trigeminal ganglion cells to examine in detail the nature and time course of functional recovery of mechanoreceptive afferents following nerve transection with microsurgical repair of the infraorbital nerve (ION) branch of the trigeminal nerve in adult rats. Response measures include rapid vs.

Pediatric facial fractures: occurrence of concussion and relation to fracture patterns.

Background: Children and adolescents with injuries resulting in facial fractures are a population that is potentially at risk for suffering concomitant concussion. Concussion results in a variety of physical symptoms and often affects cognition, emotion, and sleep. These effects can have a significant impact on academics and social functioning.

The incidence of C5 palsy after multilevel cervical decompression procedures: a review of 750 consecutive cases.

Study Design: Retrospective review of 750 consecutive multilevel cervical spine decompression surgeries performed by a single spine surgeon.

Objective: To determine the incidence of C5 palsy in a large consecutive series of multilevel cervical spine decompression procedures.

Summary Of Background Data: Palsy of the C5 nerve is a well-known potential complication of cervical spine surgery with reported rates ranging from 0% to 30%.
