Summary
Olfactory groove meningiomas are often large at diagnosis. Microsurgical techniques allow safe resection with low morbidity and no recurrence in this case series.
Area of Science:
- Neurosurgery
- Oncology
- Neuropathology
Context:
- Olfactory groove meningiomas constitute 8-18% of intracranial meningiomas.
- These tumors frequently present at large sizes upon diagnosis.
- Surgical management is key for large olfactory groove meningiomas.
Purpose:
- To retrospectively analyze clinical outcomes, surgical results, and complications.
- To evaluate the safety and efficacy of microsurgical techniques for olfactory groove meningiomas.
- To assess recurrence rates and long-term follow-up after resection.
Summary:
- Thirteen consecutive cases of olfactory groove meningiomas were operated on between 1995 and 2003.
- Patients underwent uni- or bifrontal craniotomies with either complete resection or tumor removal and duramater coagulation.
- One patient died post-operatively from brain infarction, and three experienced transient cerebrospinal fluid fistulas. No symptomatic recurrences were observed during a 3.3-year follow-up.
Impact:
- Demonstrates that olfactory groove meningiomas can be safely resected with low morbidity using current microsurgical techniques.
- Highlights the potential for successful long-term outcomes with no symptomatic recurrence.
- Provides valuable data for neurosurgical management strategies for these challenging tumors.
