Résumé : On the long list of cranio-facial dysostoses, the Hallermann-Streiff syndrome or oculo-mandibulo-dyscephaly with hypotrichosis is one of the most uncommon. The first case was described by Aubry in 1893 under the name of 'Alopecie congenitale suturale'. Since then, 50 other cases have been reported. None of these reports was performed on an anthropometrical basis. In the authors' opinion, however, the only valid way to evaluate a case of cranio-facial dysostosis is with the help of anthropometry. From the literature follows that this syndrome is invariably characterised by seven major symptoms: dyscephaly and bird face, dental anomalies, harmonious nanism, hypotrichosis, skin atrophy, bilateral cataract and microphthalmy.
