Optimal invasive key-hole neurosurgery with a miniaturized 3D chip on the tip: Microendoscopic device
A 65-year-old man with a 6-month history of left-sided weakness underwent an MRI scan. This showed left foramen magnum meningioma as shown in Figure -. He underwent a left far lateral craniotomy on the craniocervical junction with tumor 3D-ME visualization [], and gross total removal under pure 3D-ME-controlled technique [] was performed. Neither, microscope or normal 2D endoscope was used. Three months postoperative, the left-sided weakness improved and 6 months later, patient neurological deficit totally disappears. The follow-up MRI scans showed no residual or recurrent tumor as shown in Figure and .
