Biopsy of pineal region neoplasms is frequently accomplished by way of endoscopic transventricular access or using an image-guided, computer-assisted stereotactic approach. ⋯ This method appears to be a safe alternative to stereotactic biopsy using other trajectories and provides adequate tissue for definitive diagnosis.

The outcomes of conservative and operative treatment of os odontoideum in children remain unclear. Our objective was to study the outcomes of conservative and surgical treatment of idiopathic os odontoideum in children and compare these outcomes in age- and treatment-matched nonidiopathic children with os odontoideum. ⋯ III.

The pediatric skull base may present anatomic challenges to the skull base surgeon, including limited sphenoid pneumatization and a narrow nasal corridor. The rare nature of pediatric skull base pathology makes it difficult to gain experience with these anatomic challenges. The objective of this study was to create a 3-dimensionally (3D) printed model of the pediatric skull base and assess its potential as a training tool. ⋯ A 3D printed model of the pediatric skull base may provide a realistic model to help participants gain experience with anatomic limitations characteristic of the pediatric anterior skull base.

The operating microscope is a foundational tool in modern neurosurgery. Operating microscopes serve increasingly as the lynchpin for highly sophisticated visualization platforms incorporating many complementary technologies. ⋯ In this article, we document our experience using the QEVO microinspection tool in a series of complex cranial neurosurgery procedures. This report focuses on the handling, visualization, and overall utility of the QEVO tool for achieving optimal visualization in deep cranial corridors.

Case Reports
Microsurgical Resection of Petroclival Meningioma via the Posterior Petrosal Approach: 3-Dimensional Operative Video.
Petroclival meningiomas are complex, deep-seated lesions related to many critical neurovascular structures. We present the case of a 44-year-old woman who had presented with a history of severe facial pain, hearing loss, and tinnitus on the left side, associated with left facial hypoesthesia (Video 1). Preoperative magnetic resonance imaging demonstrated a mass highly suggestive of a left petroclival meningioma. ⋯ Laboratory training is essential to be familiarized with the complex intraoperative neuroanatomical nuances. The patient provided written informed consent for the report of her case and operative video. The anatomical images were provided courtesy of the Rhoton Collection, American Association of Neurological Surgeons/Neurosurgical Research and Education Foundation.
