Fat implant is superior to muscle implant in vestibular schwannoma surgery for the prevention of cerebrospinal fluid fistulae.
Meticulous sealing of opened air cells in the petrous bone is necessary for the prevention of cerebrospinal fluid (CSF) fistulae after vestibular schwannoma surgery. We performed a retrospective analysis to determine whether muscle or fat tissue is superior for this purpose. ⋯ Fat implantation is superior to muscle implantation for the prevention of CSF leakage after vestibular schwannoma surgery and should, therefore, be used for the sealing of opened air cells in cranial base surgery.

Balance deficits after sports-related concussion in individuals reporting posttraumatic headache.
Posttraumatic headache (PTH) may affect neurocognition after sports-related concussion. To our knowledge, no studies have examined how PTH affects balance after concussion using dynamic posturography. The purpose of this study is to compare balance after concussion between athletes reporting PTH and athletes not reporting PTH. ⋯ Current literature proposes that PTH is associated with cognitive deficits. Our study indicates that PTH may also contribute to increased balance deficits. We believe the deficits may be a result of increased sensory organization challenges after injury. Clinicians should be mindful of these findings when managing concussed athletes reporting headache.

Subdural motor cortex stimulation for central and peripheral neuropathic pain: a long-term follow-up study in a series of eight patients.
In certain chronic neuropathic pain (CNP) conditions, extradural electrode implantation is preferred to a subdural location for motor cortex stimulation (MCS) therapy, but the rationale for this preference remains debatable. We provide documented long-term results of subdural MCS in CNP. ⋯ In this small series, subdural MCS seemed a tolerable approach in the long term for CNP patients. In addition, subdural MCS provided a therapeutic effect comparable to that obtained with extradural placement.

Total sacrectomies are performed for extensive en bloc tumor resections. Exposure traditionally combines a posterior approach with a laparotomy to facilitate vascular control. We present a case of a total en bloc sacrectomy performed entirely through the posterior approach, thereby avoiding the need for a laparotomy. ⋯ With the use of interspace distraction and sacral elevation to facilitate vascular control, a total sacrectomy was performed without the need for the anterior exposure of a laparotomy.

Giant pediatric midline tumors of the posterior fossa involving the fourth ventricle and the tectal region are difficult to approach and present a high risk of postoperative neurological deficits. Children with sequelae such as cerebellar mutism and ataxia experience a compromise in their quality of life. Here, we present our combined transventricular and supracerebellar infratentorial approach to avoid complications of vermian splitting. ⋯ The combined transventricular and supracerebellar infratentorial approach offers a unique possibility of safely removing giant pediatric midline tumors. Splitting of the cerebellar vermis is not necessary for removal of such tumors.
