Pineal tumors are rare but surgically challenging due to their deep location and proximity to major veins and brainstem.1,2 Getting a biopsy along with an endoscopic third ventriculostomy is essential before surgical resection.3,4 The supracerebellar infratentorial approach provides direct symmetrical exposure of the pineal region inferior to the vein of Galen.5,6 3-Dimensional (3D) exoscopes are increasingly used due to better ergonomics, greater depth of field, and equivalent image quality of microscope. The endoscope provides angled optics to visualize hidden areas of tumor adherent to neurovascular structures, avoiding blind dissection. These become especially advantageous during suboccipital keyhole surgery in the sitting position, which averts both cerebellar retraction and frequent soiling of the endoscope. ⋯ Histopathology was a high-grade papillary tumor. Magnetic resonance imaging confirmed gross total resection. This is probably the first report of a supracerebellar infratentorial keyhole approach for gross total resection of a giant pineal tumor, effectively using the better ergonomics and depth of field of a 3D exoscope along with angled optics provided by an endoscope, resulting in an excellent outcome.

Advances in endoscopic endonasal transsphenoidal surgery have led to improved postoperative outcomes after pituitary adenoma resection, including reduced length of stay, complications and readmission rates, without compromising safety and satisfaction. ⋯ Implementing an interdisciplinary, perioperative protocol for transsphenoidal endoscopic pituitary surgery improves length of stay while minimizing readmissions and surgery-related complications.

Middle meningeal artery (MMA) embolization for the treatment of chronic subdural hematomas (cSDHs) is becoming increasingly prevalent. It is essential to optimize the safety and cost effectiveness of the postprocedural management. In this study, we examined our cases over time to determine the most appropriate postprocedural destination. ⋯ MMA embolization for cSDH is a safe procedure with low rate of procedure-related complications. In carefully selected patients, the necessity ICU admission postoperatively should be weighed against better hospital resource utilization.

Population-based studies on the cause of readmission within 90 days after surgery or radiotherapy for metastatic spine tumors are scarce. We aimed to investigate the risk factors for readmission within 90 days after initial surgical or radiation treatment for metastatic spine tumors. ⋯ These study findings offer a better understanding of the causes of readmission following radiotherapy or surgical treatment in patients with metastatic spine tumors, and these results can help reduce postoperative morbidity and medical costs among these patients.

Screw loosening is a common complication of pedicle screw internal fixation surgery. This study aimed to investigate whether the application of a porous scaffold structure can increase the contact area between screws and bone tissue by comparing the bone ingrowth and screw-bone interface of porous scaffold core pedicle screws (PSCPSs) and hollow lateral hole pedicle screws (HLHPSs) in the lumbar spine of Bama pigs. ⋯ Compared with HLHPSs, PSCPSs possessing a porous scaffold core could promote bone ingrowth and osseointegration, resulting in an effective enhancement of the combined area of the screw-bone interface.
