Objective: To systematically identify criteria used to diagnose patients with trigeminal nerve injury. Study design: A systematic review of the literature registered in the PROSPERO database. Inclusion criteria: patients diagnosed with nerve injury of the sensory divisions of the maxillary or mandibular branches of the trigeminal nerve, with reported tests and criteria used for diagnosis and persistent pain or unpleasant sensation associated with nerve injury. Results: 28 articles included. Diagnostic tests included clinical neurosensory tests (CNT) (89%), thermal quantitative sensory testing (25%), electromyography (7%) and patient interview (14%). Neuropathic pain was assessed using visual analogue scale (39%), use of neuropathic medication (7%), questionnaires including McGill and PainDETECT (21%). Functional impact was assessed in 14% and psychological impact in 7% of articles. Methodology in performing CNT, application of diagnostic terms and diagnostic grading of nerve injury was not consistent among the included articles making direct comparison of results difficult. Conclusion: Recommendations for assessment and diagnosis of trigeminal nerve injury have been made based on the best available evidence from the review. There is an urgent requirement for a consensus in diagnostic criteria, criteria for assessment and outcome reporting between stakeholder organisations in order to progress knowledge in this field.
