In endoscopic transsphenoidal surgery for pituitary adenoma with suprasellar extension, the prolapse of the stretched floppy diaphragma sellae can obstruct the surgical corridor, posing challenges during pituitary surgery. We introduce a simple postural change technique to mitigate this issue and share our clinical experience. ⋯ A simple postural change technique effectively manages prolapsed floppy diaphragma sellae, enhancing visualization and surgical accessibility during endoscopic transsphenoidal pituitary surgery.

Case Reports
Safe endovascular recanalization of internal carotid artery occlusion using retrograde aspiration angiography.
Cerebral infarction, resulting from acute internal carotid artery (ICA) occlusion, typically manifests with a wide ischemic area and severe symptoms. Mechanical thrombectomy proves effective within 24 hours of disease onset and in less ischemic infarction core. However, in cases with well-developed collateral flow and mild symptoms, conservative treatment is initially selected. If symptoms worsen or ipsilateral hemisphere perfusion decreases, superficial temporal artery-middle cerebral artery anastomosis is considered. Revascularization therapy may also be effective. Contralateral angiography allows for ipsilateral blood flow verification once complete revascularization is achieved, albeit with potential treatment-related complications. Here, we describe retrograde angiography using an intermediate catheter (IMC) and contralateral contrast injection to achieve safer revascularization. ⋯ Advancements in IMC technology facilitate distal catheter guidance to the ICA, even in proximal occlusion. Combining this technique with contralateral imaging allows us to confirm the extent of occlusion and recanalization status without antegrade imaging, making recanalization therapy safer.

The contralateral transmaxillary corridor improves access to anterior petrous apex lesions back to the level of the internal auditory canal without the need to mobilize the paraclival internal carotid artery. In this Video 1, we present the case of 31-year-old female patient who presented with new left abducens palsy during pregnancy. Imaging revealed a heterogeneous enhancing extradural mass within the left petrous apex region extending posterior to the horizontal segment of the petrous internal carotid artery, consistent with chondrosarcoma. ⋯ The patient consented to the procedure. A complete resection of the mass was performed with pathology demonstrating a grade 2 chondrosarcoma. The patient tolerated the procedure without any complications, the left abducens palsy resolved in follow-up by 3 weeks, and a multidisciplinary tumor board recommended postoperative observation without adjuvant therapy.7 An endoscopic endonasal and contralateral transmaxillary approach is a feasible option for petrous apex lesions such as chondrosarcoma.

Intracranial pressure (ICP) is a well-established measure in managing not only traumatic brain injury but also nontraumatic intracranial bleeding or edema. When ICP increases despite nursing or medical management, ICP may be reduced via surgical measures. Deciding whether to perform a craniotomy vs. craniectomy (whether the bone flap is replaced or not, respectively) is commonly made intraoperatively following preoperative planning. While ICP monitoring (ICPm) is standard pre- and postoperatively, its intraoperative utility remains understudied. ⋯ These results bring forward the potential pivotal role of intraoperative ICPm in guiding surgical strategies for elevated ICP, suggesting a novel data-driven approach to intraoperative management of decompression surgery.

Chiari malformation is a structural defect in the brain, affecting the cerebellum, brainstem, upper cervical cord, and cranial base, with severe cases involving herniation through the foramen magnum. This condition can significantly impact the patient's quality of life. Given the elective nature of surgical treatment for Chiari 1 malformations, many patients seek supplemental information on YouTube. This study aimed to evaluate the quality, accuracy, reliability, and educational value of YouTube videos on Chiari malformation decompression surgery. ⋯ This study highlights the need for improved regulation and the promotion of high-quality medical content on online platforms. Healthcare providers should guide patients toward reliable resources and consider collaborating with content creators to enhance the quality of educational materials available online. Improved oversight and quality control on platforms like YouTube can better support patient education and clinical decision-making.
