Abstract
The pharyngeal arches develop in the human embryo around five weeks of pregnancy. Disorders in the development of the first and second pharyngeal arches may lead to significant malformations of the face and ears. Syndromes involving the pharyngeal arches often involve tooth abnormalities, requiring regular dental follow-up with specialized management by a multidisciplinary team.
