Probable case of Binder syndrome in a skeleton from Quarai, New Mexico

Binder syndrome (maxillonasal dysplasia) is a not uncommon disorder reported in the clinical literature and is characterized by hypoplastic development of the midface. An extensive review of the paleopathology literature did not reveal any examples of Binder syndrome. In this paper, a probable case of Binder syndrome in a female skeleton, 16-17 years at age of death, from Quarai, New Mexico (ca. AD 1375-1450) is presented. This case was identified during standard documentation prior to repatriation at the National Museum of Natural History, Smithsonian Institution. The skull of this individual (381243) exhibits unusual facial features, including an underdeveloped midface, flattened glabella, absent nasal spine, and apparent alveolar prognathism, in addition to a vertebral anomaly. All of these characteristics are consistent with skeletal dysmorphologies associated with Binder syndrome. Measurements of the Quarai skull are compared with published data on Binder patients and normal control groups in order to quantify the nature of the observed morphology. Univariate analysis of craniometric/cephalometric data provides further support for a diagnosis of Binder syndrome, as critical measurements on the Quarai skull are consistent with those reported in Binder patients and significantly different from those reported for normal control groups. In addition to presenting a probable prehistoric case of Binder syndrome, this paper demonstrates the applicability of using direct comparisons of clinical data to help identify unusual conditions in skeletal remains.
