Ventral decompressive surgery of the craniocervical junction is performed to manage a variety of conditions, including basilar invagination, which can be associated with platybasia. We have noted that the anatomic changes of platybasia could affect the height of the odontoid over a line drawn along the nasal cavity floor, the palatine line (PL). This anatomic change may influence the use of nasal endoscopic surgery for patients with platybasia who also have basilar invagination. We investigated whether the height of the craniocervical junction is elevated over the PL in patients with and without platybasia. ⋯ Platybasia is associated with an increase in the odontoid and craniocervical junction over the PL. This increase in height has implications for endoscopic approach selection in patients with platybasia. Platybasia patients with basilar invagination may be better suited to a transnasal approach.

To report our preliminary experience with the Pipeline flow-diverter stent for the endovascular treatment (EVT) of intracranial aneurysms. ⋯ This study shows that the Pipeline stent is useful for EVT of fusiform and wide-necked intracranial aneurysms. Moreover, the stent is well tolerated with a low rate of intra-stent stenosis at short-term follow-up. However, technical improvements are needed to ensure safe and precise use of the device.
