Article Synopsis
- Chiari malformation type I (CM-1) involves the herniation of brain tissue through the foramen magnum, presenting various clinical symptoms, which this study investigates through brain imaging and analysis of morphometric features.
- The research reviewed data from 72 CM-1 patients and 26 healthy volunteers, finding distinct differences in brain structure volumes, including decreased volumes in critical areas and increased tonsillar size in CM-1 patients.
- The study concludes that the amount of neural tissue at the foramen magnum strongly correlates with the need for surgical intervention and the presence of syrinxes, indicating a compressive phenomenon in the posterior fossa as a key factor in CM-1 symptoms.

Objective: To investigate the role of seasonality on postoperative complications after spinal surgery.
Methods: Data were obtained from the American College of Surgeons National Surgical Quality Improvement Program database from 2011 to 2018. Current Procedural Terminology codes were used to identify the following procedures: posterior cervical decompression and fusion, cervical laminoplasty, posterior lumbar fusion, lumbar laminectomy, and spinal deformity surgery.
Study Design: Retrospective comparative cohort study using the National Surgical Quality Improvement Program.
Objective: The aim of this study was to evaluate trends in the annual number of PSOs performed, describe the patient populations associated with each cohort, and compare outcomes between specialties.Summary of Background Data:Pedicle subtraction osteotomies (PSO) are complex and advanced spine deformity surgical procedures performed by neurosurgeons and orthopedic surgeons.
Background: The Knosp criteria have been the historical standard for predicting cavernous sinus invasion, and therefore extent of surgical resection, of pituitary macroadenomas. Few studies have sought to reappraise the utility of this tool after recent advances in visualization and modeling of tumors in complex endoscopic surgery.
Objective: To evaluate our proposed alternative method, using 3-dimensional (3D) volumetric imaging, and whether it can better predict extent of resection in nonfunctional pituitary adenomas.
