Hemifacial microsomia is a rare form of craniofacial anomaly displaying abnormalities of the derivatives of the first and second branchial arches. A diagnosis of hemifacial microsomia is made if the patient presents with microtia, hypoplastic mandible, maxilla or the zygomatic arch on one side of the face. Bilateral involvement is rare. Here we present a rare form of the syndrome which presented with bilateral ear involvement and hearing deficit. Radiographs helped in diagnosing the case as hemifacial microsomia. The condition is extremely complex and heterogenous. Accurate diagnostic workup is necessary to differentiate this condition from other conditions of the first and second arch derivatives. We describe here the characteristic clinical and radiographic features which help to improve the knowledge on the disorder.
