To evaluate long-term outcomes of surgical resection for congenital brain tumors (CBTs) in infants under one year of age and to identify factors related to survival. ⋯ Surgical resection remains crucial for treating CBTs in infants under one year, yet the aggressive nature of malignant tumors results in suboptimal outcomes regarding prognosis.

Chiari malformations, characterized by the herniation of cerebellar tonsils through the foramen magnum, are complex neurosurgical conditions that pose significant diagnostic and therapeutic challenges.1 Traditional interventions, such as foramen magnum decompression, have been the mainstay of treatment but are not universally effective, especially in cases with underlying atlantoaxial instability. However, recent studies highlight the importance of atlantoaxial instability in their pathogenesis, shifting the therapeutic focus towards atlantoaxial fixation.2 Research shows that atlantoaxial fixation can effectively address the underlying instability, leading to better symptomatic relief and neurological outcomes compared to traditional decompression methods.3,4-17 The findings from these studies consistently demonstrate that atlantoaxial instability is a critical factor in the development of Chiari malformations. Atlantoaxial fixation not only resolves the mechanical instability but also leads to significant symptomatic relief and improved neurological outcomes. ⋯ This surgical Video 1 illustrates a case of a 20-year-old male patient with tonsillar herniation, syringomyelia, atlantooccipital assimilation, atlantoaxial instability, basilar invagination and dorsolumbar scoliosis, who was successfully managed with cervical fixation using a bilateral C1 lateral mass and C2 transpedicular screw construct. This surgery was able to achieve clinical and radiologic improvement without the need for a foramen magnum decompression. The patient consented to the procedure and to the publication of his images.

Delayed symptomatic hyponatremia (DSH) is one of the common complications following endoscopic endonasal surgery (EES). Currently, published studies have predominantly focused on delayed postoperative hyponatremia, while there is relatively limited research on DSH. ⋯ The incidence rate of DSH after EES in patients was 16.8%. Knosp grade ≥3, intraoperative cerebrospinal fluid leaks, serum sodium concentration on the second day after surgery, and postoperative DI were associated with the occurrence of DSH.

Graft failure is a common complication of cranioplasty. Revision cranioplasty is required to overcome this complication. However, no previous studies have reported outcomes in revision cranioplasty with 3-dimensional (3D) custom-made titanium implants. We describe our experience with 3D titanium implants in patients with revision cranioplasty. ⋯ Initial cranioplasty with PMMA provides a longer time period than the AG before the revision. However, both of them have similar outcomes based on length of hospital stay and cranial defect area. Custom-made 3D titanium implant is a good option for revision cranioplasty to prevent implant failure and reduce patients' cosmetic concerns.

To evaluate the short-term surgical outcomes and the reimbursement patterns, after treatment of type 2 odontoid fractures using the anterior or posterior approach. ⋯ In this matched analysis, the anterior approach for type 2 odontoid fractures was superior to the posterior approach. The anterior approach was associated with significantly shorter operation times, hospital stays, fewer transfusions, nonroutine discharges, and higher reimbursements.
