Surgical clipping has become a relatively rare procedure in comparison to endovascular exclusion of cerebral aneurysms. Consequently, there is a declining number of cases where young neurosurgeons can practice clipping. For this reason, we investigated the application of a new 3-dimensional (3D) simulation and rehearsal device, Surgical Theater, in vascular neurosurgery. ⋯ Surgical Theater proved to be realistic in replicating vascular neurosurgery scenarios for rehearsal and simulation purposes. Moreover, it was shown to be useful for didactic purposes, allowing young neurosurgeons to take full advantage and learn from senior colleagues to become familiar with this demanding neurosurgical subspecialty.

Parasympathetic network damage results in facial nerve damage, sublingual ganglion degeneration, sublingual gland dysfunction, and dry mouth. In this study, subarachnoid hemorrhage (SAH) was considered to be the cause of dry mouth. ⋯ Clinical findings in infection and diseases such as Sjögren syndrome, aseptic meningitis, and SAH are similar. However, until now, SAH has not been demonstrated experimentally to cause dry mouth. Discovering that SAH might cause dry mouth might prevent unnecessary use of antibiotics and decrease morbidity due to the wrong or late diagnosis.

Microelectrode recording (MER)-guided deep brain stimulation (DBS) remains the standard electrophysiological procedure to place the DBS lead at the optimal target. When single-track MER or test stimulation yields suboptimal results, trajectory adjustments are needed. Intraoperative computed tomography (iCT) can be useful to visualize the microelectrode and verify possible adjustments. The aim of this study was to evaluate the effect of iCT in MER during frameless stereotactic DBS for Parkinson disease (PD). ⋯ iCT can reduce the number of MER tracks and increase surgical accuracy. Further studies are warranted to investigate whether iCT can reduce surgical complications and improve surgical outcomes.

Cerebral arteriovenous malformation (AVM) can rarely occur in conjunction with moyamoya disease (MMD). There is still no consensus on how to treat AVM when accompanied by MMD. In this study, we assessed the clinical features and suggested appropriate management when AVM was combined with MMD. ⋯ In this study, AVM tended to occur where the angiographic stage of MMD was higher. When AVM is combined with MMD, MMD bypass surgery is recommended based on symptoms and cerebral perfusion status. For AVM, less invasive but effective treatments, such as GKS, should be implemented as soon as possible.

We investigated the frequency of postoperative major complications, length of stay (LOS), and associated risk factors for primary C2-involved upper cervical chordoma through the combined anterior retropharyngeal-posterior approach. ⋯ Patients who are older, experience longer operative duration, or have larger tumor extension have a greater risk of postoperative major complication. The LOS can be predicted by age, preoperative neurological deficit, CZH classification, surgical approach, and surgical duration. Accordingly, patients with these risk factors should be monitored and targeted with preventative measures.
