A new feature of the ablepharon macrostomia syndrome: zygomatic arch absence

Abstract

The ablepharon macrostomia syndrome is an extremely rare congenital anomaly. It is characterised by bilateral absence or hypoplasia of lower eyelids, macrostomia and multiple other congenital anomalies. Three cases have been reported ( McCarthy and West, 1977; Hornblass and Reifler, 1985). In addition to ablepharon and macrostomia, other anomalies common to all patients include auricular deformity, nasal alar deformity, absence of lanugo hair, dry, ichthyotic skin and ambiguous genitalia. A new feature of the syndrome is described—absence of the zygomatic arches. In addition, an expanded and revised classification of the ablepharon macrostomia syndrome and related disorders is presented. Skin graft pigmentation in this black patient has been prevented by prolonged application of sun block.
