Long-Term Outcomes of FEBAIR Microsurgical Techniques in Meningioma Management

Overview

This study presents a long-term follow-up of surgical treatments for meningiomas, revealing a recurrence rate of approximately 20% over an average follow-up period of 14 years.

Background

Meningiomas are the most common primary intracranial tumors, accounting for nearly 39% of all brain lesions. This study provides data on recurrence rates and surgical effectiveness over an extended follow-up period.

Data Highlights

Key Findings

• The study included 99 patients with a median age of 56 years.
• Approximately 83% of resections achieved Simpson grades zero, I, and II.
• Recurrence occurred in ~20% of cases, with 40% of recurrent cases being giant meningiomas.
• In the non-recurrent group, 86.6% achieved Simpson grades zero, I, and II.
• The mortality rate during the follow-up period was 7%.

Clinical Implications

The findings indicate a correlation between Simpson grades of resection and recurrence rates in meningioma surgeries.

Conclusion

This study presents a relationship between the extent of resection and recurrence rates in meningioma management.
