Comparisons of ipsilateral and contralateral TGN volume between primary TN patients and controls. Box-and-whisker plot demonstrating that the ipsilateral TGN volume was significantly lower compared to the contralateral TGN volume in primary TN patients and the mean volume of bilateral TGN in healthy controls (p < 0.05). Meanwhile, the ipsilateral TGN of patients with major NVC demonstrated decreased volume compared to those with minor (and without) NVC (p < 0.05).
*statistically significant.
n.s.: not significant; NVC: neurovascular compression.
