Combined transcranial and endoscopic endonasal approach for anterior skull base meningiomas: approach and reconstruction strategies

Large anterior skull base meningiomas with sinonasal invasion pose a challenge not only for safe resection but also for tackling reconstruction of the anterior skull base. Here, in this video, the authors present the case of a 35-year-old female with a biopsy-proven WHO grade II meningioma who required a combined transcranial and endoscopic endonasal approach. This combined approach allowed for excellent tumor exposure, complete safe resection, and, importantly, durable and appropriate skull base reconstruction.
