Title: [Complex craniofacial synostoses]. Author: Meling TR, Ørstavik KH, Heiberg A. Journal: Tidsskr Nor Laegeforen; 2004 May 06; 124(9):1230-4. PubMed ID: 15131704. Abstract: BACKGROUND: Complex craniofacial synostosis is a group of rare genetic disorders characterized by premature closure of the sutures in the craniofacial skeleton and which to varying degrees affects the extremities. MATERIAL AND METHODS: On the basis of relevant literature, we present a review of syndromal craniofacial synostosis. RESULTS: Phenotypically, the complex craniofacial syndromes have many similarities. Synostosis of the sutures of the cranial vault can result in a variety of skull deformations, depending on the sutures involved, the sequence of premature closure, and the time of closure. Synostosis of the sutures in the skull base and facial skeleton leads to shallow orbits, exophthalmus, hypertelorism, midface retrusion, and prognathia. INTERPRETATION: Precise diagnosis of complex craniofacial syndromes may be difficult solely on the basis of a clinical examination. However, several of the most common syndromes are caused by mutations in genes that code for fibroblast growth-factor receptors. Children with a suspected complex craniofacial syndrome should be referred to genetic testing.[Abstract] [Full Text] [Related] [New Search]
