Background:
Although the ipsilateral craniotomy approach has been used for the removal of falcine meningioma (FM), we report a case of FM that was minimally invasively removed using a contralateral interhemispheric approach assisted with endoscopy.
Methods:
We used a contralateral approach with a small craniotomy of the FM. The tumor was detached from the surrounding tissue during internal decompression. It was dissected and coagulated endoscopically in a blind spot under a microscope, and a Simpson Grade I resection was achieved.
Conclusion:
A small craniotomy with a contralateral interhemispheric approach assisted by endoscopy allowed minimally invasive tumor removal without complications.
Insights
A minimally invasive technique for falcine meningioma (FM) removal was achieved using a contralateral interhemispheric approach with endoscopy. This method enabled complete tumor resection with minimal invasiveness and no complications.
Area of Science:
- Neurosurgery
- Minimally Invasive Procedures
- Endoscopic Techniques
Background:
- Falcine meningiomas (FM) are typically removed via ipsilateral craniotomy.
- Minimally invasive techniques are increasingly preferred for tumor removal.
Purpose of the Study:
- To describe a novel minimally invasive approach for falcine meningioma resection.
- To evaluate the efficacy and safety of a contralateral interhemispheric endoscopic approach for FM removal.
Main Methods:
- A contralateral interhemispheric approach with a small craniotomy was utilized.
- Endoscopic assistance was employed for dissection and coagulation in difficult-to-access areas.
- Internal decompression was performed before tumor detachment.
Main Results:
- A Simpson Grade I resection was successfully achieved.
- The procedure was minimally invasive, utilizing a small craniotomy.
- No intraoperative or postoperative complications were reported.
Conclusions:
- A contralateral interhemispheric approach assisted by endoscopy is a viable and safe option for minimally invasive falcine meningioma removal.
- This technique offers an alternative to traditional ipsilateral craniotomy, especially for challenging cases.
- Endoscopic assistance facilitates complete resection and minimizes invasiveness.
