Imaging of the fetal oral cavity, airway and neck

Magnetic resonance imaging has proved to be an extraordinarily useful adjunct modality in assessment of the fetal face, oral cavity, head and neck because of its soft-tissue contrast, utility for acquiring more precise planar imaging and the inherent advantage of contrast provided by fluid-filled structures, including the oropharyngeal cavity, nasal passages and vascular structures. In this review, the author presents an organized approach to assessing normal anatomical structures of the fetus. The author presents cystic and solid lesions as well as structural and developmental abnormalities and discusses potential concomitant abnormalities. Prenatal consultation, patient counseling and delivery considerations are included.
