Goldenhar syndrome is a variant of hemifacial microsomia. It is not usually associated with mental retardation; even if present it is mild to moderate. In this case both profound mental retardation and bilateral facial microsomia are present. Early identification and intervention can improve the intellectual functioning, otherwise favorable prognosis. INTRODUCTION: In 1952 Maurice Goldenhar described a variant of hemifacial microsomia called Goldenhar syndrome. It results from an aberrant development of the 1 st and 2 nd branchial arches. It has an incidence of approximately 1 in 5600, more common among males with a ratio of 2:1 and also common among whites. [1] Goldenhar syndrome is a form of occulo-auriculo-vertebral spectrum (OAVS), as a minimal sign microtia must be present. [2] It presents bilaterally in 10-33% of cases. [3] About 10% of children may have mental retardation, usually mild to moderate. [4] Here we report a case of Goldenhar syndrome with profound mental retardation which is very unusual.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
