Cephalalgia : an international journal of headache
-
Contact point headaches have been attributed to intranasal contact between opposing mucosal surfaces, resulting in referred pain in the distribution of the trigeminal nerve. In subjects with primary headaches, contact points may be associated with treatment refractoriness. We aimed to assess the benefits of surgical correction in patients with refractory migraine or transformed migraine, and radiographic evidence of contact points in the sinonasal area. ⋯ Two patients (9.5%) had increase in their headache score by less than 25%. For selected patients with refractory headaches, demonstrable contact points, and positive response after topical anaesthesia, surgical approach toward the triggering factor may be useful. Prospective studies are necessary to confirm our results.
