Tractography Delineates Microstructural Changes in the Trigeminal Nerve after Focal Radiosurgery for Trigeminal Neuralgia
PURPOSE Focal radiosurgery is a common treatment modality for trigeminal neuralgia (TN), a neuropathic facial pain condition. Assessment of treatment effectiveness is primarily clinical, given the paucity of investigational tools to assess trigeminal nerve changes. Since diffusion tensor imaging (DTI) provides information on white matter microstructure, we explored the feasibility of trigeminal...
متن کاملRadiosurgery for Trigeminal Neuralgia
Trigeminal neuralgia (TN), also known as tic douloureux, is a pain syndrome recognizable by patient history alone. The condition is characterized by intermittent unilateral facial pain. The pain follows the unilateral (>95%) sensory distribution of trigeminal nerve (V), typically radiating to the maxillary (V2) or mandibular (V3) area. Ophthalmic division (V1) pain alone occurs in <5% patients....
متن کاملTissue changes after radiosurgery for vestibular schwannomas.
The specific effects of radiosurgery on brain tumor tissue are not well understood. We review several approaches that have been used to address this issue. Correlating the radiobiology of radiosurgery with the radioclinical outcome may help to understand these tissue changes. In vivo imaging investigations are usually performed with MRI, but the use of functional and metabolic imaging, such MR ...
متن کاملCyberKnife radiosurgery for idiopathic trigeminal neuralgia.
OBJECT Gamma knife surgery is an accepted treatment option for trigeminal neuralgia (TN). The safety and efficacy of CyberKnife radiosurgery as a treatment option for TN, however, has not been established. METHODS Forty-one patients were treated between May 2002 and September 2004 for idiopathic TN at Stanford University and the Rocky Mountain CyberKnife Center. Patients with atypical pain, m...
متن کاملLinear accelerator stereotactic radiosurgery for trigeminal neuralgia.
BACKGROUND Stereotactic radiosurgery is accepted as an alternative for patients with refractory trigeminal neuralgia, but existing evidence is fundamentally based on the Gamma Knife, which is a specific device for intracranial neurosurgery, available in few facilities. Over the last decade it has been shown that the use of linear accelerators can achieve similar diagnostic accuracy and equivale...
