Hemifacial microsomia: a clinicoradiological report of three cases

Abstract

Hemifacial microsomia is a congenital malformation in which there is deficiency in the amount of hard and soft tissues on one side of the face. It is primarily a syndrome of first and second branchial arches involving underdevelopment of the temporomandibular joint, mandibular ramus, masticatory muscles, ears and occasionally defects in facial nerve and muscles. Here, we report three cases of hemifacial microsomia diagnosed based on clinical and radiographic findings. All three cases had variable presentations ranging from the mildest form that included facial asymmetry and ear deformity to the most severe and unusual form with facial nerve paralysis and spine deformity.
