Treatment of cystic craniopharyngiomas can be challenging and recurrences are frequent, even after total resection. In selected cases, less-aggressive surgery with the sole drainage of the cyst reliefs symptoms caused by mass effect and represents a valid alternative option, notably in pediatric population. We herein analyze a series of adult cystic craniopharyngiomas, managed with Ommaya Reservoir implant, focusing on local tumor control and eventual complications. ⋯ In selected patients, tailored procedures are required to achieve long-term tumor control and as well limit surgery-related morbidity. ORS could represent a safe and effective treatment option for cystic craniopharyngiomas, providing also reduced surgical-related morbidity, especially in recurrent lesions and in patients not suitable for radical surgery.

Observational Study
Anatomical Feasibility of Right Oblique Approach for L5-S1 Oblique Lumbar Interbody Fusion.
We compared left and right vascular anatomy at the L5-S1 disc space and validated the anatomical feasibility of the right oblique approach for L5-S1 oblique lumbar interbody fusion. ⋯ The vessels on the right side of the L5-S1 disc were located more laterally, and most vessels on the right side were arteries accompanying PVAT, which might minimize vessel manipulation. These results indicate that the right side of the L5-S1 disc could provide feasible access for oblique lumbar interbody fusion at L5-S1.

The anterior transpetrosal approach (ATPA) is applied to petroclival and brainstem lesions. Although neurosurgeons need to minimize the risk of neurologic complications, brain retraction is necessary for procedures of ATPA. Bridging veins (BVs) limit mobility of the temporal lobe. In the present study, BVs around the petrous bone were analyzed, focusing on the dural entrance and termination points. ⋯ TBVs entering the T-S junction or SPS with short subdural segment may limit the mobility of the temporal lobe. Changes in vascular diameter, shape, and course were detected by computed tomography venography, which was helpful to detect the subdural-meningeal transition.

With the continuous advancement of the spinal endoscopic technique in recent years, full-endoscopic operations provide a new approach for the treatment of migrated cervical disk herniation. ⋯ The postoperative Japanese Orthopaedic Association (JOA) score increased from 8 to 11 points. At 2-year follow-up, the JOA score was 16 points, the improvement rate was 88.9%, and cervical vertebrae MRI, cervical CT scan, and 3-dimensional reconstruction showed that the cervical vertebrae channel healed without vertebral fractures, bony channel collapse, adjacent segment degeneration, or intervertebral space height.

Olfactory dysfunction is a significant postoperative complication related to endoscopic transsphenoidal surgery (TSS). This study aimed to determine the impact of endoscopic TSS on olfactory function. ⋯ Endoscopic single-nostril transseptal TSS for sellar or parasellar tumor resection has minimal impact on olfactory function.
