To assess morphologic features of the prechiasmatic sulcus (PS) in Chiari malformation type I (CM-I). ⋯ SA value was approximately 25% greater in the CM-I group than in the control group; thus, CM-I patients had more vertical groove. The percentage of narrow-type (NSG + NFG) PS in the CM-I group was higher than in the control group.

Cervical laminoplasty is generally not indicated in patients with kyphosis because of poor outcomes. Therefore, data on the effectiveness of posterior structure-preserving techniques in patients with kyphosis are limited. This study investigated how laminoplasty with muscle and ligament preservation can benefit patients with kyphosis via risk factor analyses of postoperative complications. ⋯ Although patients with kyphosis had a significantly higher incidence of AP, C2-C7 cervical laminoplasty with muscle and ligament preservation may not be contraindicated in selected patients with kyphosis by risk stratification for AP and AL using newly identified risk factors.

Chordomas are a rare form of aggressive bone cancer and are associated with poor quality of life (QOL). The present study sought to characterize demographic and clinical characteristics associated with QOL in chordoma co-survivors (caregivers of patients with chordoma) and assess whether co-survivors access care for QOL challenges. ⋯ Our findings suggest that younger co-survivors are at high risk for adverse emotional QOL outcomes. In addition, more than one third of co-survivors did not know about resources to address their QOL issues. Our study may help guide organizational efforts to provide care and support to patients with chordoma and their loved ones.

To investigate the efficacy and safety of posterior atlantoaxial fusion (AAF) with C1-2 pedicle screw fixation for atlantoaxial dislocation (AAD) in pediatric patients with mucopolysaccharidosis IVA (MPS IVA). ⋯ Posterior AAF with C1-2 pedicle screw fixation is effective and safe for AAD in pediatric patients with MPS IVA. However, the procedure is technically demanding and should be performed by experienced surgeons with strict multidisciplinary consultations.

Hyperspectral Imaging (HSI) in Brain Tumor Surgery - Evidence of Machine Learning-Based Performance.
Hyperspectral imaging (HSI) has the potential to enhance surgical tissue detection and diagnostics. Definite utilization of intraoperative HSI guidance demands validated machine learning and public datasets that currently do not exist. Moreover, current imaging conventions are dispersed, and evidence-based paradigms for neurosurgical HSI have not been declared. ⋯ In a limited number of publications, neurosurgical HSI has demonstrated unique capabilities in contrast to the established imaging techniques. Multidisciplinary work is required to establish communicable HSI standards and clinical impact. Our HSI paradigm endorses systematic intraoperative HSI data collection, which aims to facilitate the related standards, medical device regulations, and value-based medical imaging systems.
