Rhinogenic trigger zones for migraine: evaluation and surgical treatment

ABSTRACT

Many theories were proposed for the explanation of migraine. In this study, an attempt to locate and treat rhinogenic trigger zone responsible for triggering migraine attack was done. Fifty patients with resistant migraine were studied. Thirty-five patients were due to nasal abnormalities in the area of middle meatus, posterior part of the septum, middle turbinate, ethmoid and sphenoid sinuses. Endoscopic correction of these restrictive pathomorphological changes resulted in 80% permanent improvement, 11.5% substantial improvement and 8.5% little or no improvement
