Design This study is an operative video. Results Resection of the recurrent skull base meningioma is still challenging, especially if the tumor involves or encases the carotid artery. In this video, we describe our experience with the successful treatment of a recurrent skull base meningioma, which involved the entire cavernous sinus and the internal carotid artery. A 53-year-old male presented with a 1-year history of progressing right-side complete oculomotor palsy and facial dysesthesia. The patient had previously undergone craniotomy for the right-side petroclival cavernous meningioma (Fig. 1A and B). Total 8 years after the first surgery, the remaining portion of the cavernous sinus grew up and extended into the posterior fossa (Fig. 1C). Then the second surgery was performed to resect only the posterior fossa component (Fig. 1D). However, the follow-up magnetic resonance imaging revealed an aggressive tumor regrowth in 2 years. The tumor occupied the right middle fossa with an extension to the posterior fo ssa and infratemporal fossa (Fig. 1E and F). We scheduled to perform gross total resection of the tumor through a combined transzygomatic transcavernous and extended middle fossa approach with preparation for vessel reconstruction. Mild adhesion between the tumor and the cavernous carotid artery facilitated complete resection of the intracavernous component of the tumor (Fig. 2A–C). Conclusion A combination of skull base approaches provides multidirectional operative corridors and wide exposure of the skull base lesions.The link to the video can be found at https://youtu.be/DB_WXFeyBvo.
