To investigate the role of advancing age on postoperative complications and revision surgery after fusion for scoliosis. ⋯ In this study, age was associated with increased risk of hemorrhage, PE, infection, and refusion. With the aging population, the role of patient age on postoperative healing and outcomes deserves deeper investigation after repair of adult idiopathic scoliosis.

Meningocele and meningoencephalocele of the lateral wall of the sphenoidal sinus (LWSS) are rare lesions, crossing the borders of multiple disciplines such as ear-nose-throat, maxillofacial, and neurologic surgery. We reviewed our surgical experience to analyze the role of the endoscopic endonasal approach and consider these pathologies from different perspectives. ⋯ Endoscopic endonasal surgery is a safe and effective approach for meningocele and meningoencephalocele of LWSS; it allows resection of herniated tissue and repair of the osteodural defect. The favorable clinical outcome and the possible effectiveness on seizures lead us to support this approach as first minimally invasive treatment also in presence of epilepsy, as a first low risk epilepsy surgical procedure.

Management of Incidental Dural Tear During Lumbar Spine Surgery. To Suture or Not to Suture?
Incidental durotomy (ID) during lumbar spine surgery is a frequent complication of growing clinical relevance as the number and complexity of spinal procedures increases. Yet, there is still a lack of guidelines for the treatment of ID with a large heterogeneity of established surgical techniques. The aim of this study was to investigate the efficacy of dural suturing in patients having ID during degenerative lumbar spine surgery, compared with other dural closure techniques. ⋯ Based on our results, the dural closure technique after ID does not seem to influence revision surgery rates due to cerebrospinal fluid leakage and its complications. Further prospective randomized studies are needed to confirm our results.

The Trans-Visible Navigator: a see-through neuronavigation system using augmented reality.
The neuronavigator has become indispensable for brain surgery and works in the manner of point-to-point navigation. Because the positional information is indicated on a personal computer (PC) monitor, surgeons are required to rotate the dimension of the magnetic resonance imaging/computed tomography scans to match the surgical field. In addition, they must frequently alternate their gaze between the surgical field and the PC monitor. ⋯ The main advantage of the present system is that it achieves volumetric navigation in contrast to conventional point-to-point navigation. It extends augmented reality images directly onto real surgical images, thus helping the surgeon to integrate these 2 dimensions intuitively.

Meningiomas are the most common primary benign brain tumor. Radiosurgery (primary or adjuvant) allows excellent local control. The Geriatric Scoring System (GSS) for preoperative risk stratification and outcome prediction of patients with meningiomas has been reported previously. The GSS incorporates 8 tumor and patient parameters on admission. A GSS score greater than 16 was reported previously to be associated with a more favorable outcome. We assessed the validity of the GSS score and its influence on outcome in patients treated with Gamma-Knife radiosurgery (GKRS). ⋯ The GSS, used for risk stratification and outcome prediction in patients with meningiomas, seems valid for patients undergoing single-session GRKS. A GSS score greater than 16 is associated with a better long-term functional status and tumor control.
