Summary
Spinal meningioma surgery using posterior laminectomy offers excellent outcomes. Most patients regain mobility, and complete tumor removal is achievable without complex approaches, leading to low recurrence rates.
Area of Science:
- Neurosurgery
- Oncology
Background:
- Spinal meningiomas are tumors arising from the meninges of the spinal cord.
- Long-term outcomes of surgical management for spinal meningiomas are important for patient prognosis.
Purpose of the Study:
- To analyze the long-term outcomes of spinal meningioma surgery.
- To evaluate the effectiveness of posterior laminectomy for tumor resection.
- To determine factors influencing recurrence rates.
Main Methods:
- Retrospective analysis of 78 patients with spinal meningiomas.
- Surgical intervention over a 20-year period at a single neurosurgical unit.
- Tumor resection via posterior laminectomy.
Main Results:
- 98% complete tumor resection achieved.
- 95% of patients regained independent mobility postoperatively.
- Only one recurrence noted after 14 years.
- Posterior laminectomy was sufficient for anteriorly located tumors.
Conclusions:
- Posterior laminectomy is an effective and sufficient surgical approach for spinal meningiomas.
- Complex surgical techniques are not necessary for complete resection.
- Dural base excision may not be required to achieve low recurrence rates.
