Headache and rhinosinusitis: A review
Cephalalgia, Ahead of Print.
Purpose of reviewTo explain our current understanding of headache attributed to rhinosinusitis, an often inappropriately diagnosed secondary headache.Recent findingsRecent studies have shown that headache attributed to rhinosinusitis is often over-diagnosed in patients who actually have primary headache disorders, most commonly migraine. Failure to recognize and treat rhinosinusitis, however, can have devastating consequences. Abnormalities of the sinuses may also be treatable by surgical means, which may provide headache relief in appropriately selected patients.SummaryIt is important for the practicing physician to understand how rhinosinusitis fits into the differential diagnosis of headache, both to avoid overdiagnosis in patients with primary headache, and to avoid underdiagnosis in patients with serious sinus disease.
