To study the anatomy and clinical application of monolateral pterional keyhole approaches for treating bilateral cerebral aneurysms. ⋯ Contralateral aneurysms of the M1 segment (anterior, superior, and inferior), MCA bifurcation (superior and lateral), A1 segment, A2 segment (anterior, posterior, and medial), internal carotid artery bifurcation, DICA (anterior and medial), and OICA (medial) were fully exposed from different angles and surgical maneuvers were performed via pterional keyhole approaches, including in patients presenting with subarachnoid hemorrhage.

Application of nerve root block is mainly for diagnosis with less application in intraoperative treatment. The aim of this study was to observe clinical and imaging outcomes of application of gelatin sponge impregnated with a mixture of 3 drugs to intraoperative nerve root block combined with robot-assisted minimally invasive transforaminal lumbar interbody fusion surgery in to treat adult degenerative lumbar scoliosis. ⋯ Application of gelatin sponge impregnated with 3 drugs combined with robot-assisted minimally invasive transforaminal lumbar interbody fusion for treatment of adult degenerative lumbar scoliosis is safe and feasible with advantages of good short-term analgesia effect, minimal invasiveness, short length of stay, and good long-term clinical outcomes.

The authors describe a modified technique for placement of the C1 lateral mass screw using a Steinmann pin as a guide. This technique minimizes dissection and provides atlantoaxial stabilization during arthrodesis. ⋯ The use of Steinmann pins to guide the placement of C1 lateral mass screws is safe and effective in C1-2 arthrodesis. Limiting dissection minimizes blood loss and injury, maintains efficient operative time, and assists in accurate placement of the screws. Furthermore, with less manipulation and retraction of the C2 nerve root, postoperative occipital neuralgia and the need for C2 root transection are avoided.

Parkinson disease (PD) is a major risk factor during spine surgery, and its frequency is increasing as the population ages. The study aim was to examine the influence of PD specifically on lumbar decompression surgery. ⋯ There is a significantly greater rate of perioperative complications in patients with PD undergoing elective decompression surgery. Although the difference in major complication rates was minimal, minor complications were more frequent in patients with PD.

Review Case Reports
Treating CSF Rhinorrhea without Dura Repair - A Case Report of Posterior Fossa Choroid Plexus Papilloma.
Choroid plexus papilloma revealed by nontraumatic cerebrospinal fluid (CSF) rhinorrhea has only been described 5 times, to our knowledge, in the literature. The challenges in this situation are to recognize CSF leak, to rapidly understand the pathophysiology of the leak, and to choose the best treatment strategy in emergency. We report an original case of posterior fossa choroid plexus papilloma revealed by CSF leak. We then discuss the surgical strategy and the pathophysiology of CSF leak, which is explained, in this case, by both hyperproduction of CSF and local skull base erosion. ⋯ Our case shows that 1) causal reasoning is of major importance when dealing with CSF rhinorrhea and that 2) dura repair can be avoided when treating CSF leak secondary to posterior fossa choroid plexus papilloma.
