Minimally invasive resection of a lumbar extradural schwannoma: how I do it
- 19 Downloads
Complete surgical resection of a foraminal lumbar schwannoma may require an extended surgical exposure and facetectomy and thus secondary instrumentation. The minimally invasive technique through the use of tubular retractors may represent a valid surgical alternative.
We describe the resection of a foraminal lumbar schwannoma through the use of tubular retractors, along with its advantages and limitations. A limited medial facetectomy was performed and no stabilization was needed.
Minimally invasive surgery is suitable for an efficient and safe resection of foraminal schwannomas and may help in avoiding stabilization when a limited facetectomy is performed.

In this video the authors show a minimally invasive approach through the use of tubular retractors for the resection of an extradural lumbar schwannoma. With the use of expandable retractors, the important bony landmarks were identified and after drilling of the lateral portion of the lamina and the medial third of the articular process, the schwannoma was identified. The intraoperative electrophysiological neuromonitoring helped us in localizing motor fibers and thus in performing a complete resection (MP4 182,622 kb)
