Comparative Cadaveric Analysis for Surgical Corridor and Maneuverability: Far-Lateral Approach and its Transcondylar Extension.
The necessity of partial occipital condyle (OC) resection for lesions in the ventral craniocervical junction is debatable. This study's purpose was to compare the surgical exposure of the classic far-lateral approach (FLA) and transcondylar FLA. ⋯ Transcondylar FLA can significantly increase surgical exposure compared with the classic FLA, although also increasing surgical complications. Therefore, the surgical approach should be individualized according to each lesion and patient. The results of our study may assist in surgical decision-making regarding the need for OC resection.

We present a case of a 28-year-old woman with a history of severe headaches and pituitary insufficiency. She was found to have a large, enhancing, sellar mass consistent with a pituitary adenoma. ⋯ Spontaneous involution of pituitary masses has been described but not often encountered in clinical practice. This case highlights that follow-up imaging is necessary when scheduling elective surgeries during the COVID-19 pandemic.

Balloon remodeling microcatheters are essential in assisting endovascular coiling of brain aneurysms, but the performance and pressure requirements of different balloon types when used in aneurysmal defects are currently unknown. ⋯ Scepter balloons require less pressure compared with their counterparts to adequately deform through model defects, specifically in larger aneurysm necks in smaller vessel diameters. This result could inform operators of optimal balloon type and size when trying to minimize balloon pressure in fragile brain aneurysms.

Low back pain (LBP) is increasing in the pediatric population. Advanced imaging, such as computed tomography and magnetic resonance imaging, performed for LBP imposes significant costs with little benefit. We investigated annual trends and demographic and geographic variation in spinal imaging for first-time pediatric presenters with LBP in primary care clinics. ⋯ There was significant demographic and geographic variation but no significant annual change in total diagnostic spinal imaging for pediatric patients with LBP between 2011 and 2017, with rates of advanced imaging remaining relatively low.
