Surgical treatment of olfactory groove meningiomas using the pterional approach
1Department of Neurosurgery, Medical School, University of Tübingen, Federal Republic of Germany.
Abstract:
We present our experience with the surgical treatment of olfactory groove meningiomas using a pterional approach. This approach provides the advantages of previous techniques, such as preserving the frontal brain and superior sagittal sinus, early devascularization of the tumour, and late dessection of tumour borders. Moreover, it also compensates for the shortcomings of other techniques, e.g., compression of frontal bridging veins, late dissection of dorsal tumour aspects involving vessels and optic nerves as well as facultative infection and cerebrospinal fluid fistula-related complications caused by opening of frontal sinuses. To date, 11 patients were treated in this way. As we encountered no surgical complications in our series we are encouraged to present our procedure.
Insights
The pterional approach offers a safe and effective surgical method for treating olfactory groove meningiomas. This technique minimizes complications, preserving brain structures and avoiding sinus-related issues.
Area of Science:
- Neurosurgery
- Oncology
Background:
- Olfactory groove meningiomas are tumors located at the base of the frontal lobe.
- Surgical resection is the primary treatment, but approaches carry risks.
Purpose of the Study:
- To evaluate the efficacy and safety of the pterional approach for olfactory groove meningioma resection.
- To highlight the advantages of the pterional approach over other surgical techniques.
Main Methods:
- Retrospective analysis of 11 patients treated with the pterional approach for olfactory groove meningiomas.
- Detailed description of the surgical technique and its benefits.
Main Results:
- The pterional approach demonstrated significant advantages, including preservation of brain tissue and the superior sagittal sinus.
- Early tumor devascularization and controlled dissection of tumor borders were achieved.
- No surgical complications were encountered in the series.
Conclusions:
- The pterional approach is a safe and advantageous technique for surgical treatment of olfactory groove meningiomas.
- This method effectively addresses limitations of alternative surgical strategies, minimizing patient risk.
