Outcomes of gamma knife radiosurgery for trigeminal neuralgia after a minimum 3-year follow-up

Long term efficacy and patient satisfaction of microvascular decompression and gamma knife radiosurgery for trigeminal neuralgia

“…Pain relief was noted in 72.7% of the patients. In the series by Park et al [21] with a minimum follow up of 3 years 94.1% of the patients had a good treatment outcome at the last follow up. In the study by Han et al [22] the actuarial recurrence free survival rates were 84.8%, 76.1%, 69.6%, 63.0% and 45.8% at 1, 2, 3, 4 and 5 years after radiosurgery.…”

Measurement of Trigeminal Neuralgia Pain

“…Since the publication of the initial study, several researchers have used the scale to determine outcomes after RS. [19][20][21] The major advantage of the BNI-PS is that it was specifically created for measuring treatment outcomes in TN; however, there are many significant limitations. First, the scale itself is a composite of 3 outcome domains.…”

Clinical Outcomes of Gamma Knife Radiosurgery in the Treatment of Patients with Trigeminal Neuralgia

“…The other 11 BNI pain intensity scale studies we reviewed included patients where previous surgical procedures were performed in a fraction of patients [4, 5, 10–12, 15–19] or all patients [14]. Of the 10 studies where previous surgical procedures were performed in a fraction of patients, nine reported outcomes in terms of categorizing patients in BNI class I-IIIb [4, 5, 10–12, 15–18].…”

“…Of the 10 studies where previous surgical procedures were performed in a fraction of patients, nine reported outcomes in terms of categorizing patients in BNI class I-IIIb [4, 5, 10–12, 15–18]. Specifically, Riesenburger et al [10] classified 58.6% of patients in BNI class I-IIIb (median followup = 48 months), Kondziolka et al [5] classified 71% of patients in BNI class I-IIIb at three years, Dhople et al [18] classified 72% of patients in BNI class I-IIIb (median followup = 29 months), Han et al [11] classified 76.7% of patients in BNI class I-IIIb (mean followup = 58 months), Dhople et al [17] classified 81% of patients in BNI class I-IIIb (median followup = 5.6 years), Matsuda et al [16] classified 82% of patients in BNI class I-IIIb (median followup = 37 months), Little et al [15] classified 83% of patients in BNI class I-IIIb (median followup = 6.3 years), Dellaretti et al [4] classified 89.5% of patients in BNI class I-IIIb (mean followup = 20.3 months), and Park and Hwang [12] classified 94% of patients in BNI class I-IIIb with a minimum followup of 3 years. Pan et al [19] reported clinical outcomes with respect to BNI class I, which contained only 5.7% of patients.…”
