Objective: to evaluate the relationships between headache and nasal obstruction or nasal allergy on a group of Italian school children.
Methods: One hundred twenty-six children suffering from headache, were enrolled in the study. All patients underwent an accurate clinical history, a complete ENT objective examination, an Anterior Active Rhinomanometry, an analysis of nasal mucociliary transport time and a skin test on the inner forearm.
Results: Nasal resistances were increased in 101 out of 105 of children (96.2%) affected by severe headache (group A) and in 5 out of 21 (23.8%) of those affected by sporadic headache (P < 0.0001), for an odds ratio of 80.0 (95% CI, 19-343). The analysis of mucociliary transport time offered results comparable with those of the Anterior Active Rhinomanometry.
Conclusions: Dysfunctions of nasal physiology, as stated by the alteration of nasal resistances and nasal mucociliary transport, seem to be able to affect the development and the characteristics of headaches; specifically we found that children with an altered nasal physiology have more severe and more frequent attacks of headache.
