Staged Repositioning in Endoscopic Endonasal Odontoidectomy Maximizes Decompression while Allowing Preservation of the C1 Anterior Arch: A Technical Note.

World Neurosurg 2021 Apr 30. Epub 2021 Apr 30.

Department of Neurological Surgery, University of Pittsburgh Medical Center, Pittsburgh, PA 15213; Department of Otolaryngology, University of Pittsburgh Medical Center, Pittsburgh, PA 15213. Electronic address:

Background: Preservation of the anterior arch of C1 in endoscopic endonasal odontoidectomy has been proposed as an alternative to complete C1 arch resections, potentially affording less destabilization of the craniocervical junction. Nonetheless, this approach may limit the decompression achieved. In this case, intra-operative repositioning allowed maximal decompression while preserving the anterior arch of C1. Read More

Optic Canal Decompression: Concepts and Techniques: 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2021 Apr 30. Epub 2021 Apr 30.

Department of Neurological Surgery, Mayo Clinic, Phoenix, Arizona, USA.

The optic canal (OC) is a bony channel that transmits the optic nerve (ON) and ophthalmic artery (OphA) as they course through the lesser wing of the sphenoid bone to the orbital apex. The OC is involved in a variety of intracranial and extracranial pathologies,1 and opening of the canal may be necessary in order to achieve adequate exposure, better disease control, and vision preservation.2 Depending on the location of the pathology and its relationship with the optic nerve, the OC may be decompressed through an open transcranial approach or an endoscopic endonasal approach.

Department of Neurological Surgery, Rutgers New Jersey Medical School, Neurological Institute of New Jersey, Saint Barnabas Medical Center, Robert Wood Johnson Barnabas Health, Newark, New Jersey, United States.

Basilar invagination is a congenital or acquired craniovertebral junction abnormality where the tip of the odontoid process projects through the foramen magnum which can cause severe symptomatic compression of the brainstem and spinal cord. If left untreated, patients can develop progressive quadriparesis. Traditionally, basilar invagination can be treated with cervical traction and posterior stabilization. Read More
