OBJECTIVE: This tertiary care experience examines the utility of magnetic resonance neurography (MRN) in the management of peripheral trigeminal neuropathies. MATERIALS AND METHODS: Seventeen @entity1 with clinically suspected peripheral trigeminal neuropathies ( @entity129 ) were imaged uniformly with 1.5-T examinations. MRN results were correlated with clinical and surgical findings in operated @entity1 and the impact on clinical management was assessed. RESULTS: Clinical findings included @entity158 (14/17), sensory changes (15/17), motor changes (2/17) and palpable masses (3/17). Inciting events included prior dental surgery (12/17), @entity130 (1/17) and idiopathic incidents (4/17). Non-affected side nerves and trigeminal nerves in the intracranial and skull base course were normal in all cases. Final diagnoses on affected sides were nerve @entity32 (4/17), @entity2950 in continuity (2/17), LN transection (1/17), scar entrapment (3/17), @entity166 (1/17), low-grade injuries (3/17) and no abnormality (3/17). Associated submandibular gland and sublingual gland @entity4 -like changes were seen in 3/17 cases because of parasympathetic effects. Moderate-to-excellent MRN-surgical correlation was seen in operated (8/17) @entity1 , and @entity2950 and nerve transection were prospectively identified in all cases. CONCLUSION: MRN is useful for the diagnostic work-up of suspected @entity1897 @entity1 with significant impact on clinical management and moderate-to-excellent correlation with intra-operative findings. KEY POINTS:     MRN substantially impacts diagnostic thinking and management in @entity1897 .     MRN has moderate-to-excellent correlation with intra-operative findings.     MRN should be considered in pre-surgical planning of @entity1897 subjects.
