Minimally Invasive Resection of Lumbar Schwannomas: Expanding the Role of the Transpars Approach.

Abstract

Lumbar nerve root schwannomas are rare tumors that can cause debilitating radicular pain and motor dysfunction due to nerve root compression. This study introduces a novel minimally invasive transpars approach for their removal, aiming to preserve spinal stability while ensuring complete resection. Two cases of lumbar schwannomas affecting the L2 and L3 nerve roots were managed using the transpars approach. A detailed description of the surgical technique and intraoperative monitoring protocol is provided. Complete tumor removal was achieved in both cases without complications or the need for spinal stabilization. Postoperative recovery was uneventful, with resolution of symptoms and confirmation of total resection on imaging. The transpars approach represents a safe and effective alternative to traditional methods for managing lumbar nerve root schwannomas. It minimizes invasiveness, avoids spinal stabilization, and allows for rapid postoperative recovery.
