Background and ObjectivePatients with trigeminal neuralgia (TN) and multiple sclerosis (MS) are often treated with medications or a surgical procedure. However, there is little evidence that such treatments result in 50% pain reduction and improvement in quality of life. The aim of this systematic review is to evaluate the clinical effectiveness of treatments in patients with MS and trigeminal neuralgia.MethodsWe searched Medline, EMBASE, and the Cochrane Collaboration database from inception until October 2016. Two authors independently selected studies for inclusions, data extraction, and bias assessment.ResultsAll studies were of low quality using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. For medical management, 10 studies were included, of which one was a randomized controlled trial. Two studies were on the use of misopropol, unique to patients with MS. For surgical therapy, 26 studies with at least 10 patients and a minimum of 2 years follow-up were included. All types of surgical procedures are reported and the results are poorer for TN with MS, with 50% having a recurrence by 2 years. The main complication was sensory loss. Many patients had to undergo further procedures to become pain free and there were no agreed prognostic factors.ConclusionsThere was insufficient evidence to support any 1 medical therapy and so earlier surgery may be preferable. A patient with TN and MS has therefore to make a decision based on low-level evidence, beginning with standard drug therapy and then choosing a surgical procedure.
