Gamma Knife radiosurgery for trigeminal neuralgia: when?
- 28 Downloads
As widely known, classic trigeminal neuralgia (TN) represents one of the most common craniofacial pain syndromes [9, 15]. Medical therapy, as first-line treatment, is effective in controlling pain in a high percentage of cases at short-time period; however, this rate does significantly decrease over time . Microvascular decompression (MVD) represents historically the reference technique .
Stereotactic radiosurgery (SRS), such as Gamma Knife radiosurgery (GKRS), has increasingly become a popular treatment for TN, for the lack of treatment-related toxicity and mortality, less invasiveness, and good pain control rates [2, 14, 15, 16]. However, the right timing for GKRS or MVD is still a great matter of debate and data in literature are uneven . Other SRS techniques, such as LINAC based SRS, namely,...
