Nose and headache: what have we learned? Naso e cefalee : cosa abbiamo imparato

Sinonasal involvement in secondary headache has long been interpreted as sinusitis and overestimation has been a problem in the past. In the last 20 years, the innovative interpretation of contact points between the lateral nasal wall and the septum as triggering cause of facial pain via the trigeminovascular system has gained importance in nasal secondary headaches. Also in this case, the prevalence and relevance has been misinterpreted in the beginning, undermining the success rate of pain improvement after surgical removal of these contact points. Therefore, studies have started to concentrate on the need of suitable preoperative evaluation to define the ideal, responsive candidate for surgical management of this form of headache. This article analyzes the outcome of these studies and tries to highlight the need for long-term follow-up to finally determine the relevance of surgical treatment for this particular headache form.
