OBJECT To evaluate long-term outcomes of patients who have undergone stereotactic radiosurgery for cavernous sinus meningiomas, the authors retrospectively reviewed their 14-year experience with these cases. METHODS One hundred seventy-six patients harbored meningiomas centered within the cavernous sinus. Seventeen patients were lost to follow-up review,(More)
Ablation or deep brain stimulation in the internal segment of the globus pallidus (GPi) is an effective therapy for the treatment of Parkinson's disease (PD). Yet many patients receive only partial benefit, including varying levels of improvement across different body regions, which may relate to a differential effect of GPi surgery on the different body(More)
OBJECT Pituitary adenomas are fairly common intracranial neoplasms, and nonfunctioning ones constitute a large subgroup of these adenomas. Complete resection is often difficult and may pose undue risk to neurological and endocrine function. Stereotactic radiosurgery has come to play an important role in the management of patients with nonfunctioning(More)
OBJECT Deep brain stimulation (DBS) of the thalamus is used for the treatment of patients with medically refractory essential tremor (ET). The authors evaluated patient outcomes after DBS surgery. METHODS Clinical outcomes were evaluated in 19 patients who had undergone DBS surgery by using the Fahn-Tolosa-Marin clinical tremor rating scale. All adverse(More)
OBJECTIVE Stereotactic radiosurgery has been used for patients with high-risk cavernous malformations of the brain. We performed radiosurgery for patients with symptomatic, imaging-confirmed hemorrhages for which resection was believed to be associated with high risk. This study examines the long-term hemorrhage rate after radiosurgery. METHODS We(More)
BACKGROUND Aggressive (atypical or malignant) meningiomas are difficult tumors to manage. We review the local control and survival rates of patients with aggressive meningiomas after multi-modality therapy that included stereotactic radiosurgery (SRS). METHODS Thirty patients had SRS for treatment of malignant (n = 12) or atypical (n = 18) meningiomas.(More)
OBJECTIVES The purpose of this study was to evaluate the results following Gamma Knife thalamotomy (GKT) for medically refractory essential tremor in a series of patients in whom open surgical techniques were not desirable. METHODS Thirty-one patients underwent GKT for disabling essential tremor after medical therapy had failed. Their mean age was 77(More)
Neuromodulation is the functional modification of neural structures through the use of electrical stimulation. Its most clinically applicable use is deep brain stimulation (DBS) of basal ganglia structures in Parkinson's disease (PD) and essential tremor (ET). More recently, it has been used as a means of treating dystonic movement disorders. The main(More)
