This study aimed to perform a survival analysis of patients with multicentric low-grade gliomas (MLGGs) and to assess the influence of various prognostic factors on progression-free survival (PFS) and overall survival. ⋯ This integrative analysis of MLGGs patients revealed that age younger than 31 years, pure MLGG, and oligodendroglioma were significantly associated with improved PFS, and pure MLGGs was an independent prognostic factors for PFS.

The portion of the occipital condyle that is safe to remove remains controversial in the transcondylar approach. We aimed to correlate the gain in exposure with incremental removal of the occipital condyle to determine if there is a point where further drilling yields diminishing gains. ⋯ Progressive removal of the occipital condyle yielded a linear increase in exposure without an ideal point beyond which the drilling was futile. However, the impact of condylectomy was greater for our low target compared with our high target.

Advancements in modern medicine have led to longer life expectancy. Literature on spinopelvic fixation in elderly patients is limited. We investigated morbidity and mortality in octogenarians who underwent spinopelvic fixation. ⋯ With an aging population, the number of patients requiring spinopelvic fixation will continue to grow. Spine surgeons must carefully weigh benefits and risks in patients with multiple comorbidities.

Spinal masses can be diagnosed by clinical and radiographic examinations. Infrequently, pseudotumors may be due to retained masses after surgical interventions. In fact, these spinal or paraspinal expansions are caused by iatrogenic foreign bodies. Pseudotumors are mentioned as textilomas. ⋯ There are no specific clinical and paraclinical manifestations for retained surgical foreign bodies. The number of cases of textilomas associated with spinal surgery are few in comparison with abdominal or thoracic interventions. It is better to integrate textiloma in the differential diagnosis of soft-tissue masses in the paraspinal region with surgical history. Although the definitive treatment of textilomas is surgical elimination of the foreign body, exact evaluation of surgical site before its closure is essential to prevent these cases.

The evaluation of sources of error when preparing, printing, and using 3-dimensional (3D) printed head models for training purposes. ⋯ Spatial accuracy errors occur consistently in every 3D fabricated model. These errors are derived from the fabrication process, the image registration process, and the surgical process of registration.
