[Congenital eyelid ptosis and dental anomalies in the Francheschetti syndrome].

The observation of an 11-years-old child is presented. He had bilateral congenital palpebral ptosis and multiple facial malformations, like maxillary and mandibular hypoplasia, dental malpositions, ogival palace, anomalies of the external ear, lesions determined by a latero-facial dechyscence (perforation 6, 7, 8). The affection was produced by a embryogenesis disturbance following the existence of two pathological genes. Their actions were overlapped during the 7--8 and 11 weeks of embryonic life, which caused damages in the maxillary and mandibular bones suture, which allow the formation of the inferior and middle stage of the face.
