Coronal view of the face of a fetus with holoprosencephaly demonstrates a decreased interorbital distance between the calipers (+), which measured 37 mm compared with a normal of 52 mm for a fetus of this gestational age (32 weeks). It is important to examine the fetal face and skull during prenatal ultrasound examinations because abnormalities of these structures may indicate the presence of other, more subtle anomalies, syndromes, chromosomal abnormalities, or even rarer conditions, such as infections or metabolic disorders. Asymmetric microphthalmos (arrows) is also evident. pellucidum (100%). This chapter aims to describe the systematic evaluation of fetal orbits using ultrasound (US) to identify most common anomalies. Ultrasound diagnosis: There is a spectrum of midline abnormalities of the nose in association with holoprosencephaly, including: arhinia (complete absence of the nasal structures), proboscis (soft tissue appendage projecting from just below the forehead) and single nostril (usually central).
