Surgery of Spinal Schwannomas : Preservation of Neuronal Function and Prevention of Complications

Abstract

  Schwannomas are the most frequently encountered spinal tumors and can occur at any spinal level. The consensus treatment strategy is to remove the tumor, decompress the spinal cord and nerve roots, and confirm the histology. Most of these tumors are localized in the intradural, extramedullary space and can be removed using a standard posterior approach. However, surgery needs to be planned carefully to preserve neurological function and avoid complications for tumors located anterior to the spinal cord, exhibit a large mass, or dumbbell-shaped.

  In this article, the surgical strategies for spinal schwannomas and their outcomes are discussed.
