Hemifacial microsomia: a series of three case reports.

Hemifacial Microsomia (HFM) is an asymmetric craniofacial malformation which results in hypoplasia of the components of the first and second branchial arches. There can be various anomalies, which include conductive hearing loss which is caused by external and middle ear deformities. HFM is the second most common congenital facial anomaly which is seen after cleft lip/palate. For the pre-surgical evaluation of this anomaly, diagnostic imaging and classification of the facial structures, based on OMENS classification, is of prime importance. The management of this developmental malformation is multidisciplinary. We are presenting a series of three cases with diverse clinical and radiographic features which ranged from mild facial asymmetry and ear malformation to facial paralysis.
