OBJECTIVE Hemifacial spasm (HFS) is considered as a reversible pathophysiological condition mainly induced by continuous vascular compression of the facial nerve root exit zone (REZ) at the cerebellopontine angle. As an offending vessel, vertebrobasilar artery tends to compress much more heavily than others. The authors analyzed HFS caused by(More)
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)
The use of silver in the past demonstrated the certain antimicrobial activity, though this has been replaced by other treatments.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)
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)
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)
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. Between March 2003 and January 2009, four patients underwent bilateral globus pallidus internus (GPi) DBS and six(More)
BACKGROUND The purpose of this study was to introduce a combination procedure with double C-shaped skin incision and an adjusted dual-floor burr hole to prevent skin complications on the scalp with deep brain stimulation (DBS) surgery. METHODS Between March 2000 and March 2010, 504 DBS electrodes were implanted in 268 patients. We included both bilateral(More)
Microelectrode recording (MER) is widely used during deep brain stimulation (DBS) procedures because MER can identify structural borders and eloquent structures, localize somatotopic arrangements, and provide an outline of the three-dimensional shapes of target nuclei. However, MER may cause intracranial hemorrhage. We preformed single track MER during DBS(More)
Microvascular decompression (MVD) for hemifacial spasm (HFS) is regarded as the gold-standard treatment due to its efficacy and durability. However, some patients still suffer from delayed recurrence after initially successful MVD.In this study, we describe our clinical experience in a single institute following up initially successful MVD for HFS 5 or more(More)
