Association between neurovascular contact and clinical characteristics in classical trigeminal neuralgia: A prospective clinical study using 3.0 Tesla MRI

BackgroundPrevious studies demonstrated that a severe neurovascular contact (NVC) causing displacement or atrophy of the trigeminal nerve is highly associated with classical trigeminal neuralgia (TN). There are no studies describing the association between the clinical characteristics of TN and seve...

Zusammenfassung:	BackgroundPrevious studies demonstrated that a severe neurovascular contact (NVC) causing displacement or atrophy of the trigeminal nerve is highly associated with classical trigeminal neuralgia (TN). There are no studies describing the association between the clinical characteristics of TN and severe NVC. MethodsClinical characteristics were prospectively collected from consecutive TN patients using semi-structured interviews in a cross-sectional study design. We evaluated 3.0 Tesla MRI blinded to the symptomatic side. ResultsWe included 135 TN patients. Severe NVC was more prevalent in men (75%) compared to women (38%) (p
