[Deflected cephalic presentation. Apropos of 80 cases].

Between 1974 and 1986, we have observed 80 deflected cephalic presentations in the Maternity of Hopital Edouard Herriot in babies weighing more than 2,000 g. They are divided in 34 brow presentations, 27 faces and 14 Bregma. The diagnosis was often made late. Caesarean section is the rule in brow and mento-posterior face presentations. There was no fetal trauma.
