Implication

Comparative imaging study reveals proximal and severe trigeminal nerve compression in trigeminal neuralgia, highlighting anatomical markers to guide surgical decompression.

Key Points

To identify specific anatomical characteristics of neurovascular compression (NVC) associated with trigeminal neuralgia (TN) compared to asymptomatic nerves.
Analyzed 30 patients with Type 1 TN and 15 asymptomatic controls using 3-T MRI with balanced fast-field echo and MR angiography.
Evaluated 90 trigeminal nerves categorized into three groups: 30 symptomatic ipsilateral, 30 asymptomatic contralateral, and 30 control nerves.
Generated virtual cisternoscopy and coronal reconstructions to assess nerve cross-sectional area, diameter, and the degree and site of NVC.
Arterial NVC was identified in 57% of symptomatic nerves, 43% of contralateral nerves, and 17% of control nerves, demonstrating significant differences in NVC presence, nerve distortion, and compression site (p < 0.001).
Compression located at the proximal nerve (odds ratio 10.4) and visible nerve indentation or displacement (odds ratio 4.3) served as the strongest predictors of TN.
Decreased nerve cross-sectional area occurred in patients with TN independently of NVC severity, while overall compression severity increased with patient age.
