[Trichorhinophalangeal syndrome : analysis of craniofacial architecture in six cases (author's transl)]

Abstract

The trichorhinophalangeal syndrome, first described by Giedon in 1966, is a condition characterized not only by skeletal, nasal, and phanerian anomalies, but by typical changes in craniofacial architecture : the vertical height of the face and cranium is increased, and there is broadening of the sagittal maxillomandibular width compensatory bilateral retroalveoli. According to Delaire, who analyzed the craniofacial architecture, the primary etiological feature of the characteristic craniofacial modifications observed in this syndrome is a reduction in size of the craniofacial basal structure.
