Mastoid effusion on temporal bone MRI in patients with Bell’s palsy and Ramsay Hunt syndrome

Abstract This study aimed to investigate the incidence of mastoid effusion on temporal bone magnetic resonance imaging (MRI) in patients with Bell’s palsy (BP) and Ramsay Hunt syndrome (RHS), and evaluate the usefulness of mastoid effusion in early differential diagnosis between BP and RHS. The inci...
