Epilepsy, Functional, and Pain Neurosurgery
This chapter covers several aspects of the management of seizures and epilepsy relevant to a general neurosurgical practice. First, all candidates should know how to manage a patient presenting with a new-onset seizure or in status epilepticus with a brain lesion or after a craniotomy. Second, they are expected to be able to explain how to perform fundamental epilepsy procedures such as a temporal lobectomy for hippocampal sclerosis or resection of an epileptogenic lesion. Third, it is useful to have a clear process in place for mapping language and motor function for the resection of tumors located in the eloquent cortex. Lastly, the thought process behind developing an appropriate plan for the surgical management of movement disorders and the technical nuances of managing such cases are discussed. Historically, surgery for pain has been a large part of general neurosurgical practice. A variety of destructive and decompressive interventions have been developed over the years, and a number of comprehensive textbooks have summarized neurosurgical involvement with management of all kinds of medically refractory pain syndromes. It is included in the core neurosurgical education curriculum and is an integral part of neurosurgical knowledge that is tested during the oral board examination. Not surprisingly, cases involving complex pain conditions that require neurosurgical interventions may show up during examinations, and it is expected that examinees are comfortable performing these interventions and able to discuss indications, surgical details, outcomes and complications. Cases include trigeminal neuralgia, cordotomy versus morphine pain pump for cancer pain and a spinal cord stimulator.
