Hemifacial microsomia

Unilateral underdevelopment of the facial tissues, including muscles and bones. [from HPO]

Concept ID:
Congenital Abnormality

Goldenhar syndrome

Craniofacial microsomia (CFM) includes a spectrum of malformations primarily involving structures derived from the first and second branchial arches. Characteristic findings include facial asymmetry resulting from maxillary and/or mandibular hypoplasia; preauricular or facial tags; ear malformations that can include microtia (hypoplasia of the external ear), anotia (absence of the external ear), or aural atresia (absence of the external ear canal); and hearing loss. Severity can range from subtle facial asymmetry with a small skin tag in front of an otherwise normal-appearing ear to bilateral involvement (typically asymmetric), microtia/anotia with atresia of the ear canals, microphthalmia, and respiratory compromise from severe mandibular hypoplasia. Other craniofacial malformations including cleft lip and/or palate can be seen. Non-craniofacial malformations, especially vertebral, renal, cardiac, and limb, can be seen. [from GeneReviews]
