Binder's syndrome (nasomaxillary dysplasia): an uncommonly common disorder.

Binder's syndrome or nasomaxillary dysplasia is a disorder characterized by hypoplastic development of the midportion of the midfacial skeleton and its associated soft tissue manifestations. The disorder is probably more common than initially believed with only 40 cases described previous to 1980. However, since 1980, 127 cases have been reported. One case of Binder's syndrome treated with onlay split cranial (calvarial) bone grafts is presented. The technique of using split calvarial bone grafts has become increasingly popular in craniofacial surgery and facial trauma reconstruction. A literature review of Binder's syndrome is outlined and the technique of using split calvarial bone grafts is described. An analysis of the skeleton and soft tissue characteristics of Binder's syndrome is detailed and treatment options discussed.
