PY - 2023 T2 - Timor's Ultrasonography of the Prenatal Brain, 4e AB - KEY POINTSFetal ears are not routinely evaluated in prenatal anatomical screening.High-resolution sonography enables assessment of the fetal auditory system by demonstration of the pinnae, external meatus, and tympanic rings.Imaging of the cochlear labyrinths is possible only in the early second trimester.Detection of auricular abnormalities can provide useful information for genetic counseling.An abnormal tympanic ring in a fetus with microtia may indicate congenital aural atresia and an increased risk of postnatal conductive hearing loss.
