title: [Hemifacial microsomia and cardiac malformations. Apropos of 2 cases].
abstract: The authors report two cases of infants with complex heart disease comprising transposition of the great vessels, and a major unilateral facial anomaly involving the ear and the mandible, conforming to the description of hemifacial microsomia. The facial anomalies seen are defined and placed in the classification of known syndromes. The incidence of heart disease associated with facial microsomia is about 20% and in 2/3 of cases it is a ventricular septal defect or a tetralogy of Fallot. An analysis of aetiological factors shows that syndromes of the first two branchial arches are usually sporadic and that they may be the result of intra-uterine disease. The mechanism of the facial lesions is probably vascular.
