Objective:
To analyze which factors influence the operative outcome, and compare advantages and disadvantages of relative surgical approaches.
Methods:
Eleven cases with the foramen magnum meningioma were operated by using posterior approach with lateral extension.
Results:
Complete removal of the tumor was performed in 7 patients (7/11, 64%), subtotal resection in 2 cases (2/11, 18%) and partial resection in 2 cases (2/11, 18%). There were no operative death and significant complication.
Conclusion:
The posterior approach with lateral enlargement is sufficient to expose and remove foramen magnum tumors without expensive bone resection.
Insights
The posterior approach with lateral extension effectively treats foramen magnum meningiomas, achieving high rates of complete tumor removal with minimal complications. This surgical technique is sufficient for tumor resection without extensive bone removal.
Area of Science:
- Neurosurgery
- Oncology
Background:
- Foramen magnum meningiomas are tumors located at the base of the skull.
- Surgical approaches to these tumors vary, impacting outcomes.
Purpose of the Study:
- To analyze factors influencing operative outcomes for foramen magnum meningiomas.
- To compare the advantages and disadvantages of different surgical approaches.
Main Methods:
- Eleven patients with foramen magnum meningiomas underwent surgery.
- A posterior surgical approach with lateral extension was utilized.
Main Results:
- Complete tumor removal was achieved in 7 patients (64%).
- Subtotal resection occurred in 2 patients (18%), and partial resection in 2 patients (18%).
- No operative deaths or significant complications were reported.
Conclusions:
- The posterior approach with lateral enlargement provides adequate exposure for foramen magnum tumor removal.
- This technique is sufficient without requiring extensive bone resection.
