We describe the setup and use of different 3-dimensional (3-D) recording modalities (macroscopic, endoscopic, and microsurgical) in our laboratory and operating room and discuss their implications in neurosurgical research and didactics. We also highlight the utility of 3-D images in providing depth perception and discernment of structures compared with 2-dimensional (2-D) images. ⋯ This is the first report in the literature of the methodology for obtaining 3-D endoscopic endonasal images using the 2-D endoscope. The use of 3-D imaging is invaluable in neurosurgical research and education, as it provides immediate depth perception (third dimension), allowing efficient understanding of key spatial relationships. Integration of 3-D imaging in neurosurgical residency programs may increase learning efficiency and shorten learning curves. However, use of 3-D imaging should not replace direct hands-on practice.

Meningiomas are the most common type of benign brain tumor, and the incidence of meningioma in women is more than twofold higher than in men. Several studies have demonstrated that hormones are somehow related to the growth of meningiomas. ⋯ This is the first report of a case in which an LHRH agonist promoted the growth of a pre-existing meningioma. We suggest that patients with a history of meningioma who are receiving LHRH agonist treatment should be closely monitored.

The craniocervical junction is a complex anatomic location that contains the occipital bone, atlas, axis, and important complex ligamentous structures. The stability of this region is ensured only with the help of ligaments. ⋯ The occiput should not be involved in the fusion area when the alar ligaments are preserved during surgery for a C2 lesion.

Posterior cervical foraminotomy is a valuable treatment option for cervical radiculopathy. Here the authors present their technique and results in the treatment of a series of patients suffering from osseous foraminal stenosis. ⋯ This retrospective analysis shows that posterior endoscopic decompression is a successful option in the treatment of osseous cervical foraminal stenosis.
