Migraine misdiagnosis as a sinusitis, a delay that can last for many years

[摘要] BackgroundSinusitis is the most frequent misdiagnosis given to patients with migraine.Therefore we decided to estimate the frequency of misdiagnosis of sinusitis among migraine patients.MethodsThe study included migraine patients with a past history of sinusitis. All included cases fulfilled the International Classification of Headache Disorders, 3rd edition (ICHD-III- beta) criteria. We excluded patients with evidence of sinusitis within the past 6 months of evaluation. Demographic data, headache history, medical consultation, and medication intake for headache and effectiveness of therapy before and after diagnosis were collected.ResultsA total of 130 migraine patients were recruited. Of these patients 106 (81.5%) were misdiagnosed as sinusitis. The mean time delay of migraine diagnosis was (7.75 ± 6.29, range 1 to 38 years). Chronic migraine was significantly higher (p < 0.02) in misdiagnosed patients than in patients with proper diagnosis. Medication overuse headache (MOH) was reported only in patients misdiagnosed as sinusitis. The misdiagnosed patients were treated either medically 87.7%, or surgically12.3% without relieve of their symptoms in 84.9% and 76.9% respectively. However, migraine headache improved in 68.9% after proper diagnosis and treatment.ConclusionsMany migraine patients were misdiagnosed as sinusitis. Strict adherence to the diagnostic criteria will prevent the delay in migraine diagnosis and help to prevent chronification of the headache and possible MOH.
