Abstract

　　We reported a case of Möbius syndrome that was diagnosed using 3D SSFP（steady-state free precession）sequences on MRI. The patient was a 9-month-old infant who had a mask-like face and swallowing, crying and smiling disturbances from birth. We successfully visualized the absence of facial, abducens and hypoglossal nerves, and hypoplasia of the brainstem, especially around the tegmentum of the pons using 3D SSFP on MRI. This reliable technique can be performed for the diagnosis of congenital facial nerve palsy.
