Prognosis comparison of different branches of trigeminal neuralgia.
We explored the remission rate of different branches of the trigeminal nerve after microvascular decompression. ⋯ Postoperative remission rate of non-V2-related branches (V1, V3) are higher than V2-related branches (V2, V1-2, V1-3, V2-3).

It is generally accepted that larger saccular intracranial aneurysms are at greater risk to rupture. We investigated whether aneurysm location influences the effect of aneurysm size on the propensity of rupture. ⋯ We observed no difference in size between unruptured and ruptured ACOM aneurysms, possibly suggesting a greater susceptibility for ACOM aneurysms to rupture at smaller sizes.

Obesity has been shown to be associated with higher rates of complications after lumbar spine surgery. However, the evidence regarding the impact of body mass index (BMI) on outcomes following posterior cervical fusions (PCFs) remains limited. ⋯ With the exception of a higher rate of deep surgical site infections seen in obese patients, increased BMI does not seem to have a major impact on 30-day outcomes following PCFs.

Decompressive craniectomy (DC) is a surgical procedure performed to manage intracranial hypertension. Once performed, patients are obligated to undergo another surgical procedure known as cranioplasty to reconstruct the cranial defect. Cranioplasty still has one of the highest rates of infection. The factors contributing to the high rate of surgical site infection (SSI) after cranioplasty are not well established. This study aims to estimate the incidence of SSI and determine its possible risk factors for patients who underwent cranioplasty using bone flaps subcutaneously preserved in abdominal pockets. ⋯ Blood glucose levels and skull defect size were the only identifiable risk factors associated with SSI. Storing bone flaps in subcutaneous abdominal pockets is cost-efficient but carries considerable risk of infection.

Neonatal hydrocephalus treatment with ultra-small valve implantation.
Neonatal hydrocephalus remains a difficult condition to manage, due to high failure rates among all management strategies. Neurosurgeons commonly manage hydrocephalus with ventriculoperitoneal shunt (VPS) implantation, and valves of variable sizes and profiles are available for implantation. This study examines primary ventricular shunt valve implantation complication rates based on valve profiles in pediatric patients with hydrocephalus. ⋯ Our review did not find a significant difference in complication rates between ultrasmall and regular valves in patients under 1 year of age. However, the etiology of shunt malfunction did differ between the groups. This work further supports evidence suggesting a surgeon's preference for shunt hardware alone does not significantly impact outcome.
