OBJECTIVE To enable physicians to remain informed of secondary GKR after multiple surgical choices. This study compares gamma knife radiosurgery (GKR) as a first and a second treatment for the management of medically refractory idiopathic trigeminal neuralgia (TN). METHODS Between May 1998 and May 2008, a total of 86 patients with idiopathic TN underwent(More)
INTRODUCTION   The use of deep brain stimulation (DBS) is growing. While these patients may suffer from traumatic brain injuries, treatment guidelines for these patients have not yet been reported. This case report demonstrates a strategy for traumatic brain injury after DBS implantation. CLINICAL PRESENTATION   A 46-year-old man underwent bilateral DBS(More)
BACKGROUND Deep brain stimulation (DBS) of the centromedian-parafascicular (CM-Pf) thalamic nuclei has been considered an option for treating Tourette syndrome. Using a large animal DBS model, this study was designed to explore the network effects of CM-Pf DBS. METHODS The combination of DBS and functional magnetic resonance imaging is a powerful means of(More)
The use of silver in the past demonstrated the certain antimicrobial activity, though this has been replaced by other treatments. However, nanotechnology has provided a way of producing pure silver nanoparticles, and it shows cytoprotective activities and possible pro-healing properties. But, the mechanism of silver nanoparticles remains unknown. This study(More)
A 43-year-old male presenting with headache and dizziness underwent craniotomy and gross total resection of an extraaxial tumor was achieved via left occipital interhemispheric approach. The tumor was diagnosed as papillary meningioma arising from the left falcotentorium with such pathologic characteristics of bronchoalveolar adenocarcinoma. At(More)
OBJECT The object of surgical treatment for hemifacial spasm (HFS) is the exclusion of pulsatile neurovascular compression of the root exit zone (REZ). However, spasm persists transiently or permanently in some cases even after complete decompression. In particular, we mainly experience these results when the vertebral artery (VA) is the offender. Hence, we(More)
Ablation of the globus pallidus internus (GPi) and thalamotomy have been extensively used in the past. Posteroventral GPi deep brain stimulation has been considered as a treatment for dystonia. However, to date, there is no report in the literature of any dystonia patient who underwent GPi deep brain stimulation who had previously undergone staged bilateral(More)
OBJECTIVES The optimal target location of deep brain stimulation (DBS) is the subject of some controversy. We implanted electrodes that could stimulate both posterior subthalamic area (PSA) and ventralis intermedius nucleus of thalamus (Vim), and examined the benefits of bilateral DBS of Vim, PSA, and Vim + PSA in patients with essential tremor (ET).

OBJECTIVE To assess the effect of relative lower amplitude and frequency for globus pallidus internus (GPi) deep brain stimulation (DBS) of cervical dystonia (CD). MATERIALS AND METHODS Between February 2005 and October 2008, 14 patients diagnosed with CD underwent bilateral GPi DBS and all the patients received low-frequency stimulation and were followed(More)
OBJECTIVE There is some debate about the effects of pallidal deep brain stimulation (DBS) or lesioning on secondary dystonia. We applied a multimodal method to maximize the treatment effects of deep brain stimulation in patients with secondary dystonia. METHODS Between March 2003 and January 2009, four patients underwent bilateral globus pallidus internus(More)
