Abstract
INTRODUCTION: To analyze 3-Tesla magnetic resonance imaging (MRI) findings and clinical features of patients with trigeminal neuralgia who underwent percutaneous balloon compression (PBC), and to determine whether these findings had an impact on the prognosis of the disease.
METHODS: A retrospective review of patients with trigeminal neuralgia who underwent PBC in Istanbul Faculty of Medicine Neurosurgery Department between January 1(st), 2007, and January 1(st), 2016, was undertaken. Of the 105 patients who underwent balloon compression, 27 patients who received surgical treatment for the first time for typical trigeminal neuralgia were included in the study. Follow-ups, clinical features, and 3-Tesla MRI findings were analyzed retrospectively. MRI findings and clinical features of patients with and without recurrence were compared. The correlation between fractional anisotropy (FA) values and recurrence was investigated.
RESULTS: Nine (33%) patients had recurrence during follow-up. The patients with recurrence had longer duration of symptoms (p=0.032), higher FA difference (ΔFA) (p=0.042) and a higher FA difference rate (p̂FA) (p=0.023). A trend towards early recurrence was found in patients with higher p̂FA, although not significant (p=0.051, R=0.319).
CONCLUSION: Symptom duration was longer and the microstructural changes were more apparent in patients with recurrence. Symptom duration and FA values obtained with 3-Tesla MRI might be a valuable input in surgical decision besides age, co-morbidities and other clinical and radiographic features.
