<unk>  (also known as Oculo-Auriculo-Vertebral/OAV syndrome) is a congenital defect characterized by incomplete development of the ear, nose, soft palate, lip, and mandible. It is associated with anomalous development of the first branchial arch and second branchial arch.
The term is sometimes used interchangeably with Hemifacial Microsomia, although this definition is usually reserved for cases without internal organ/verterbrae disruption.
It affects between 1/3500 to 1/26000 live births in the UK.
