To evaluate motor function during neuroendoscopic resectioning of deep-seated brain tumors using endoscopically guided depth electrodes. ⋯ Continuous MEP measurement using depth electrodes can serve as a new monitoring technique for endoscopic resectioning of deep-seated brain tumors.

Reconstruction of a cranial vault defect is a frequent challenge in neurosurgery. Polyetheretherketone (PEEK) is used in many types of prostheses and has been employed for 10 years in our institution (University Hospital of Toulouse, France). The objectives of this study are to describe the benefits and drawbacks of reconstructing the cranial vault defect with a PEEK prosthesis. ⋯ The use of a PEEK prosthesis in cranial vault defect reconstruction is a reliable technique with a high patient satisfaction rate and few complications. Corrections of the temporal muscle atrophy by fat grafting may be performed in addition, without increasing the rate of complications.
