Based on the location and size of anterior fossa meningiomas, there are a multitude of potential approaches and philosophies to surgical resection. This presentation explores the implementation of keyhole approaches to large and difficult anterior fossa meningiomas and explores decision making in tailoring a keyhole to specific meningioma sub-locations. Comparison between theuse of endoscopy as a sole resection strategy versus endoscopic assistance will also be explored.
This presentation will explore the authors personal case series of keyhole approaches as applied to anterior fossa meningiomas. A retrospective review of the authors keyhole meningioma series was conducted, analysizing pathology, approaches and results. 49 keyhole approaches for anterior fossa meningioma resections were conducted. 19 of the 49 meningiomas were sized above 6cm and termed giant meningiomas. The supraorbital approach was used in 42 patients, the mini-pterional approach was used in 2 patients and an extended endonasal approach in 5 patients. Gross Total resection was acheived in 45 of 49 patients and near total resection was acheived in 4 patients. Surgical videos and cases will be presented as illustrative examples.
Conclusions: Keyhole approaches to meningioma surgery are a viable operative strategy with a potential for excellent oncological results.
