Fetal external ear deformities sometimes indicate that a chromosomal abnormality is present. This study aimed to demonstrate the feasibility of fetal MRI in the evaluation of auricular deformities, as well as the added value of external auditory canal atresia. We calculated the diagnostic sensitivity, specificity, and accuracy of fetal MRI and described the imaging features. Our study showed that fetal MRI can provide valuable information to assist in the diagnosis of external ear deformities.
