Our study seeks to assess the incidence of aspiration and prolonged dysphagia needing enteral feeding at discharge (EFD) in adults after posterior fossa (p-fossa) surgery. ⋯ Although 27% patients had EFD after p-fossa surgery, only 5/56 (9%) required continued enteral feeding. Aspiration, age, and lateral surgical approach is associated with EFD. In patients who demonstrate aspiration, we recommend placement of enteral feeding tube. Although most will not require continued enteral feeding at follow-up, longer follow-ups are needed.

Multicenter Study
Delayed cerebral ischemia predicts neurocognitive impairment following aneurysmal subarachnoid hemorrhage.
Prior studies have shown that the incidence of neuropsychological deficits (NPDs) after aneurysmal subarachnoid hemorrhage (aSAH) is high despite excellent outcome according to neurologic grading scales. Delayed cerebral ischemia (DCI) occurs in 30% of patients after aSAH and significantly contributes to the mortality and morbidity of aSAH. We tested the hypothesis that DCI is associated with neuropsychological outcome. ⋯ Patients with evidence of DCI during their hospital course have a 5-fold increased risk of experiencing moderate to severe NPD compared with patients who do not develop DCI after aSAH. Secondary events occurring during acute hospitalization (DCI, hydrocephalus) may be more important to the overall neuropsychological outcome than hemorrhage (Fisher) and clinical severity (World Federation of Neurological Surgeons Grading System) scores at admission.

Clinical Trial
Unilateral endoscopic optic nerve decompression for idiopathic intracranial hypertension: a series of 10 patients.
Several surgical treatment modalities, including lumboperitoneal or ventriculoperitoneal shunt surgery, subtemporal decompression, endovascular venous sinus stenting, optic nerve decompression (OND), were used in the management of idiopathic intracranial hypertension (IIH). Each surgical technique has different advantages and disadvantages. Endoscopic OND is rarely used in the management of IIH. There are only four reported cases. The aim of this study is to describe the surgical results of patients treated with this less invasive surgical technique. ⋯ The surgical treatment of IIH by using the unilateral endoscopic OND technique is a safe and effective method in the hands of experienced surgeons with advanced endoscopic skills. A collaboration with the ophthalmology team is needed for the follow-up. Further studies with larger patient numbers is needed to compare unilateral endoscopic OND technique with the current techniques used in the surgical management of IIH.

The optimal surgical technique to treat disk herniation radiculopathy is uncertain. Advocates of sequestrectomy cite less perioperative pain and preserved disk architecture, whereas advocates of conventional diskectomy cite less frequent recurrent herniation. ⋯ No clinical advantage was found to performing a limited sequestrectomy instead of conventional microdiskectomy for the treatment of radiculopathy owing to lumbar disk herniation. Conversely, the incidence of recurrent disk herniation requiring revision surgery was lower in patients treated by more aggressive disk removal.

Pedicle screw placement is a very common procedure used to stabilize all three columns of the thoracic and lumbar spine. The purpose of this study is to evaluate the incidence of screw misplacement and related complications in patients who underwent fluoroscopy-guided transpedicular screw fixation at a neurosurgical teaching institution. ⋯ The data presented confirm that for a training and education center, transpedicular fluoroscopy-guided screw fixation remains a technically demanding procedure. As defined in this study, neurological symptoms are likely associated only with severe screw misplacement.
