Traumatic acute subdural hematomas (ASDHs) showed the highest mortality of intracranial hematomas. The aim of the current study was to identify predictive factors of poor prognosis among patients who were operated on. ⋯ The context of polytrauma, ASDH thickness, and age were major predictive factors of poor prognosis in patients with surgically evacuated traumatic ASDH. The CART algorithm using these features isolated subgroups with decreasingly unfavorable outcome, providing a relevant statistical tool to apply to future studies of traumatic ASDH.

Microvascular decompression surgery is the most effective treatment for hemifacial spasm (HFS). The vertebral artery (VA) is a larger and more elastic vessel, which makes surgical management more difficult. We introduce a surgical technique of proximal Teflon transposition with interposition (PTTI) in the vertebromedullary space for HFS with a VA offender. ⋯ The PTTI technique can be considered as another treatment option in addition to the transposition technique reported previously.

The internal carotid artery is normally positioned posterolateral to the external carotid artery at the carotid bifurcation. An anatomic variation with the internal carotid artery positioned medial to the external carotid artery, the so-called twisted carotid bifurcation (TCB), is sometimes encountered in patients undergoing carotid endarterectomy (CEA). Little is known about the TCB or the implications for CEA. ⋯ CEA for TCB can be safely performed by extension of the normal procedure, but with more meticulous preoperative assessment and gentle maneuvers. The reason for the right-side dominance is still unknown. Further investigation is needed of this anatomic entity.

Augmented reality (AR) is gaining popularity in gaming, industrial, military, and medical fields. Neurosurgical applications are currently limited and underdeveloped. ⋯ The article discusses the potential and limitations of AR in its current state and identifies strategies for successful AR application in future surgery.

Isolated hypoglossal nerve palsy caused by an atlantooccipital synovial cyst is a rare lesion, with fewer than 5 cases reported in the literature. ⋯ A left suboccipital craniectomy was performed in the region of the left hypoglossal canal, in which a cystic structure was noted at the occipital condyle and C1 vertebral junction. The nerve was adequately decompressed via aspiration of the cyst. Postoperatively, the patient substantially improved. Although rare, synovial cysts must be included in the differential diagnosis of atlantooccipital lesions.
