Aim: To assess the safety and efficacy of external trigeminal neurostimulation (e-TNS) as an add-on treatment in chronic migraine (CM) prophylaxis. Materials & methods: A prospective observational open-label study was conducted on CM patients observed at baseline and 3 months after starting daily sessions of 20 min with e-TNS (Cefaly®). Results: A total of 24 volunteers affected by CM according to the ICHD-3 were included. At the 3 month follow-up, a >30% reduction of headache days was observed in four (16.5%) of 24 patients; a marginal headache improvement was observed in ten (42%) patients, with no or minor adverse effects (four of 24 patients). Conclusion: e-TNS may constitute a safe preventive treatment in CM, its limited efficacy is not statistically significant.
