Schreiber et al1(p1772) conclude in a recent article that “88% of patients with a history of ‘sinus’ (sic) headache were determined to have migraine-type headache.” Their conclusion was largely based on the definition that the authors selected: The International Headache Society rejects chronic sinusitis, but not acute sinusitis, as a cause of headache. Because patients with acute sinusitis were excluded from the study of Schreiber et al,1 any patient with a headache could not have had a sinus headache by the definition they chose. Therefore, the authors’ conclusion that another source caused the headache was inevitable.
