Because of the effect of COVID-19 on academic opportunities, as well as limitations on travel, away rotations and in-person interviews, COVID-19-related changes could impact the neurosurgical resident demographics. Our aim was to retrospectively review the demographics of the previous 4 years of neurosurgery residents, provide bibliometric analysis of successful applicants, and analyze for the effects of COVID-19 on the match cycle. ⋯ Herein we characterized the most recently matched neurosurgery applicants, paying particular attention to changes over time in relation to the onset of the pandemic. Apart from publication volume, characteristics of residents and geographical preferences did not change with the influence of COVID-19-induced changes in the application process.

Case Reports
Novel Use of Robotically Harvested Internal Thoracic Artery in High-Flow Cerebral Bypass.
Mesenchymal tumors of the head and neck can lead to tumor-induced osteopeni, necessitating a biochemical cure to alleviate associated symptoms. We present a case of a 40-year-old man who presented with diffuse pain and wheelchair dependency secondary to a skull base mesenchymal tumor producing tumor-induced osteopeni. The tumor involved the cavernous sinus, infratemporal fossa, and middle cranial fossa. ⋯ The residual biochemical disease was then addressed via supplemental radiosurgery. The patient's clinical outcome was favorable, with regained ambulatory function and resolution of initial symptoms. Unfortunately, he developed left optic neuropathy due to the embolization of the external carotid artery feeders.

Spinal chordomas are locally aggressive and frequently recurrent tumors with a poor prognosis. Previous studies focused on a Cox regression model to predict the survival of patients with spinal chordoma. We aimed to develop a more effective model based on deep learning for prognosis prediction in spinal chordoma. ⋯ We successfully constructed a deep learning model to predict the CSS of spinal chordoma patients and proved that it was more accurate and practical than conventional prediction model. Our deep learning model has the potential to guide clinicians in better care planning and decision-making.

Lesions of the foramen magnum (FM) and craniocervical junction area are traditionally managed surgically through anterior, anterolateral, and posterolateral skull-base approaches. This anatomical study aimed to compare the usefulness of a modified extended endoscopic approach, the so-called far-medial endonasal approach (FMEA), versus the traditional posterolateral far-lateral approach (FLA). ⋯ The FMEA and FLA are both effective surgical routes to reach FM and craniocervical junction lesions. Modern skull base surgeons should have a good command of both because they appear complementary. This anatomical study provides the tools for comprehensive preoperative evaluations and selection of the most appropriate surgical approach.

To evaluate a modification to the classical Hartel technique for the treatment of trigeminal neuralgia. ⋯ Considering the inclusion of the oval foramen in a Cartesian coordinate system with axes X, Y, and Z is useful. Directing the needle to a point located 1 cm from the anterior edge of the TMJ, avoiding the medial aspect of the upper jaw ridge, allows for a safer and faster procedure.
