Branchial arch anomalies in trisomy 18
Abstract
The authors report two newborns and one fetus with trisomy 18, who have severe anomalies of the first branchial arch: extreme microtia with imperforate external meatus in two cases, and hemifacial microsomia in a third one. Those cases point to the huge phenotypic variability of the trisomy 18.
