Exoscope-assisted resection of a recurrent left frontal pilocytic astrocytoma

An exoscope strengthens the armamentarium of a neurosurgeon by improving visualization and surgeon ergonomics, reducing surgeon discomfort, and improving coordination among the surgical team. A 23-year-old male patient developed focal seizures and weakness affecting his right arm that was attributable to a recurrent left frontal lesion. Despite two craniotomies at an 8-year interval, chemotherapy, and radiation, the tumor continued to progress. In this video, the authors demonstrate resection of a recurrent left frontal pilocytic astrocytoma with the assistance of an exoscope, neuronavigation, and neuromonitoring. The exoscope can enhance surgical resectability while smoothening the surgical workflow. The video can be found here: https://stream.cadmore.media/r10.3171/2023.10.FOCVID23158.
