Deep brain stimulation hardware complications in patients with movement disorders: risk factors and clinical correlations.
Deep brain stimulation (DBS) has proven to be an effective treatment for Parkinson's disease (PD) and other movement disorders, but its usefulness is limited by complications related to the hardware. ⋯ DBS is a safe intervention with a relatively low rate of hardware complications.

Comparative StudyChanging practice patterns of deep brain stimulation in Parkinson's disease and essential tremor in the USA.
Randomized controlled studies have shown deep brain stimulation (DBS) to be an effective treatment for Parkinson's disease (PD). Outside of large-center studies, little is known about trends in DBS use in the USA. ⋯ Patients who underwent DBS in the 2007 sample were older and had more comorbidities than those in the 2000 sample; in-hospital complications remained low. Understanding trends in DBS is helpful in assessing how the technology is adopted and what relationships should be further explored.

Comparative StudyThe effect of intraventricular trajectory on brain shift in deep brain stimulation.
Brain shift during deep brain stimulation (DBS) surgery may compromise target localization. Loss of cerebrospinal fluid is believed to be the underlying mechanism, thus an intraventricular trajectory during DBS surgery may be associated with increased shift, in addition to other complications, such as intraventricular hemorrhage. ⋯ Intraventricular trajectories during DBS surgery do not appear to compromise safety or targeting accuracy.

Vagoglossopharyngeal neuralgia treated by microvascular decompression and glossopharyngeal rhizotomy: clinical results of 21 cases.
Microvascular decompression (MVD) and rhizotomy are all selected for treating vagoglossopharyngeal neuralgia (VGPN). Nonetheless, controversies still exist about their curative effect on VGPN. Here we evaluate the effectiveness of MVD together with rhizotomy of the glossopharyngeal nerve for the treatment of VGPN. ⋯ Intracranial vagoglossopharyngeal nerve MVD with glossopharyngeal rhizotomy is an effective and safe procedure to treat VGPN.

Intraoperative facial electromyography and brainstem auditory evoked potential findings in microvascular decompression for hemifacial spasm: correlation with postoperative delayed facial palsy.
Delayed facial palsy (DFP) after microvascular decompression (MVD) in patients with hemifacial spasm (HFS) is not uncommon, but the cause remains unknown. ⋯ The usefulness of intraoperative facial EMG and BAEP is limited and cannot predict DFP after MVD for HFS. We speculate that DFP after MVD is not associated with permanent nerve damage according to the EMG findings.
