Bell felcinde kararl>-durum eldeli MRG ile hızlı üç boyutlu görüntülemede fasiyal sinire vasküler basının değerlendirilmesi

Bell felcinde kararlı-durum eldeli MRG ile hızlı üç boyutlu görüntülemede fasiyal sinire vasküler basının değerlendirilmesi Amaç: Bu çalıflmanın amacı, üç boyutlu kararlı-durum eldeli hızlımanyetik rezonans görüntülemede (3D-FIESTA) fasiyal sinirin vasküler bası kalıplarını göstermek, bunun yanı sıra bu kalıplar, HouseBrackmann (HB) derecelendirmeleri ve Bell felcindeki (BP) sonuçlararasındaki korelasyonu değerlendirmektir.Yöntem:Çalıflmaya 52 BP hastası ve 25 sağlıklı kontrol dahil edildi.Ayrıca 52 hasta da sağlıklı (asemptomatik) taraf üçüncü grubu oluflturdu. Vasküler temasın varlığı, sayısı ve anatomik yerleflimine görefasiyal sinirin vasküler temas kalıpları 3D-FIESTA MRG'de sınıflandırıldı. Bulgular:Yüz sinirinin vasküler bası kalıpları bakımından gruplararasında anlamlı bir farklılık saptandı (p

Evaluation of the vascular contacts of the facial nerve on three-dimensional fast imaging employing steady-state acquisition MRI in Bell's palsy

Objective:The purpose of this study was to demonstrate the vascularcontact patterns of the facial nerve (FN) on three-dimensional fast imaging employing steady-state acquisition (3D-FIESTA) magnetic resonance imaging (MRI) and evaluate the correlation between these patterns, House-Brackmann (HB) grades and outcomes in Bell's palsy (BP). Methods:Fifty-two patients with BP and 25 healthy controls wereincluded in the study. Besides, a third group was formed by theasymptomatic sides of 52 patients. The vascular contact patterns ofthe FN on 3D-FIESTA MRI were classified with regard to the presence, number and anatomic location of the contact. Results: A significant difference was found between the groups in termsof vascular contact patterns of the FN (p<0.001). Multiple vascular contacts were more prominent in the symptomatic sides of the patients.There was a positive statistical correlation between vascular contact patterns and HB grades at presentation and at the 3rd week and 3rd monthfollow-ups (r=0.335; p=0.015, r=0.587; p<0.001 and r=0.493; p<0.001). Conclusion:Multiple vascular contacts of the FN on 3D-FIESTAMRI were found to be more common and associated with poor recovery in BP. Thus, 3D-FIESTA MRI may provide prognostic information in BP.
