Recent studies highlighted how exoscopes (EX) may be employed to approach the lateral skull base. The use of EX-assisted procedures to repair middle cranial fossa (MCF) defects has not been fully explored. Furthermore, the surgical microscope in the same circumstances has been associated with relevant limitations, such as its physical obstruction, amongst others. This study aims to present a proof of concept of EX-assisted surgery for MCF defects. ⋯ The EX allows adequate exposure of the MCF floor with the identification and preservation of key anatomical structures. The EX represents a valuable alternative to the microscope in the reconstruction of MCF defects, offering a high-quality magnification and proven maneuverability.

To determine if postoperative soft cervical orthosis use affects arthrodesis rates on a per level or construct basis following 1- and 2-level ACDFs. ⋯ Postoperative placement of soft cervical orthoses following one- or two-level ACDF was not associated with improved arthrodesis or reduced rate of revision surgery.

Intracranial trigeminal schwannomas are rare tumors that may extend into multiple cranial compartments and may emerge from the root, ganglion or intracranial portion of any of its branches.1-6 The aim of this three-dimensional operative video is to present a single-stage complete removal of a dumbbell shaped trigeminal schwannoma through a pretemporal approach. Informed consent was given by the patient for use of images and the surgical video. We describe the case of a 43 year old female presenting with chronic headaches and left facial pain in the trigeminal territory of V2 & V3. ⋯ Post-operative imaging showed complete resection of the tumoral lesion. Presurgical planning is essential for an effective and safe surgical strategy. For cases of trigeminal schwannomas with extension to the middle and posterior fossa, single stage surgery is feasible for complete and safe removal.

Retrospective Case Series OBJECTIVE: To compare predictive models for postoperative complications following anterior cervical discectomy and fusion (ACDF) using machine learning to models based on traditional comorbidity indices. ⋯ ML algorithms modeled the development of postoperative adverse events with superior accuracy to that of comorbidity indices and may guide preoperative clinical decision-making prior to ACDF.
