Comparative Study
Functional outcome after central corpectomy in poor-grade patients with cervical spondylotic myelopathy or ossified posterior longitudinal ligament.
We studied the long-term functional outcome in poor-grade patients (Nurick Grades 4 and 5) with cervical spondylotic myelopathy (CSM) or ossified posterior longitudinal ligament after central corpectomy (CC). We sought to determine whether there were any prognostic factors that could predict functional outcome in these patients. ⋯ More than three-fourths of patients with poor-grade CSM improve in their functional status after CC, with nearly 24% of patients obtaining a cure. Because patients with a duration of myelopathic symptoms of 12 months or less had the best functional outcome, early decompressive surgery should be offered to patients with poor-grade CSM.

Comparative Study Clinical Trial
Gamma knife radiosurgery for trigeminal neuralgia.
The purpose of this study was to assess outcomes in patients treated with gamma knife radiosurgery for trigeminal neuralgia. ⋯ Gamma knife radiosurgery established durable pain relief in 61% of patients with medically refractory idiopathic trigeminal neuralgia. A longer follow-up period is necessary to fully assess the incidence of late complications and recurrences.

Case Reports
A highly vascular intracranial solitary fibrous tumor treated with radiotherapy and toremifene: case report.
A case of an unusual intracranial solitary fibrous tumor with features of high vascularity and resultant difficulty at resection is presented. The use of surgery, radiotherapy, and toremifene has been successful with no recurrence after 18 months. ⋯ The use of surgery, radiotherapy, and toremifene in treatment of a vascular intracranial solitary fibrous tumor has been successful and warrants further research.

Case Reports Comparative Study
Neural damage caused by cerebral hyperperfusion after arterial bypass surgery in a patient with moyamoya disease: case report.
The prognosis of cerebral hyperperfusion syndrome after vascular reconstructive surgery, including extracranial-intracranial arterial bypass, is not poor unless intracerebral hemorrhage develops secondary to hyperperfusion. ⋯ The current case suggests that cerebral hyperperfusion after vascular reconstructive surgery can cause irreversible neural damage, which results in cognitive impairment.

Arteriovenous malformations in the cranial nerves are very rare, and only one case has been reported in the literature. To our knowledge, this is the first case report of an arteriovenous malformation in the auditory nerve. ⋯ Although arteriovenous malformations are thought to arise in the 4th to 8th weeks of gestation, this case might indicate a more specific time of emergence based on embryogenesis of the cranial nerves.
