title: [Magnetic resonance in the study of the facial nerve: methodological approach and normal anatomy].
abstract: The authors report their experience in the study of facial nerve anatomy by means of MR Imaging. The seventh pair of cranial nerves was studied in 6 healthy and informed volunteers with a super-conductive MR unit at 0.5 T using surface and head coils. Slices were 3 mm thick and were acquired on the axial and sagittal planes, when the petrous and the mastoid bones were studied. The parotid gland was studied with 5-mm slices acquired on the axial, angled axial, and sagittal planes. In all cases T1-weighted images (TR 450, TE 30) were performed. If the above research protocol, which is relatively simple and direct, is applied, the whole course of the facial nerve up to its main distal branches can be almost completely demonstrated.
