INTRODUCTIONTreacher Collins syndrome (TCS) is an autosomal dominant disorder that affects the development of structures originating from the first and second brachial arches during early embryonic development.1 The essential components of the syndrome were described by Edward Treacher Collins (1900), the ophthalmologist after whom the disease is named.2 Treacher Collins syndrome (Mandibulofacial dysostosis) is characterized by deafness, facial bone hypoplasia, chin and cheekbones), anti-Mongoloid tendency to clefts, lower eyelid coloboma and bilateral ear disorders.3 The quality of life of these people can be improved by early detection and treatment.4
