Anatomical variations of paranasal sinus and ethmoid roof type on computed tomography in patients admitted to the emergency department with migraine headache

In this study, we aimed to evaluate the anatomical variations of paranasal sinus on computed tomography (CT) in patients admitted to the emergency department due to migraine. Patients who had brain CT with a diagnosis of migraine admitted to our emergency department with a complaint of headache between June2018 and January2019 were retrospectively reviewed. Fifty-five migraine headache patients and 55 control group patients were included to this study. According to the Keros classification, the ethmoid roof height was type1 in 25, type2 in 15 and type3 in 15 of the patients with migraine. In the control group, 28 patients had type1, 14 patients type2, 13 patients type3 ethmoid roof. Anatomical variations in patients with migraine: Nasal septal deviation in 14 cases, Agger nasi cell in 6, pneumatization posterior sella turcica 1, prominent ethmoidal bulla 4, Haller cell 3, nasal septal spur 5, concha bullosa 15, pneumatized anterior clinoid process in 6, uncinate cells 4, Onodi cells 7, pneumatized crista galli 7, presence of maxillary sinus 1, frontal sinus aplasia 5, sphenoid sinus agenesis 2, frontal bulla 2, frontal sinus hyperplasia 2, paradoxical middle turbinate 1. As a result,there is no significant difference was found between the migraine patients and the control group in terms of ethmoid roof height according to Keros classification. In the control group and migrane cases,there was a significant difference in the frequency of pneumatization posterior to floor of sella turcica, nasal septal spur, uncinate cells and the presence of maxillar sinus anatomic variations.
