Long-segment intraspinal schwannomas resection: What is the minimum number of laminectomy levels required?

ABSTRACT:

Background and objectives

In canonical knowledge, long-segment intraspinal schwannomas (SCHs) require laminectomies at all involved levels for complete exposure. To evaluate a minimally invasive, limited-exposure strategy for gross total resection (GTR) of multi-level intraspinal SCHs.

Methods

A retrospective analysis was conducted on 11 patients with intraspinal SCHs involving ≥ 3 vertebral segments who underwent laminectomy confined to critical vertebrae, achieving gross total resection without full exposure of all involved levels. The surgical approach involved focused laminectomy targeting critical vertebrae, intracapsular decompression, and meticulous microsurgical dissection. Follow-up included clinical assessments and MRI evaluations at 3 months and 1-year post-surger
