[Unilateral Moebius syndrome associated with Poland's abnormality in a 25-year-old woman (author's transl)].

The authors present a case of unilateral Moebius syndrome associated with Poland abnormality in a 25-year-old woman. The patient had a complete left peripheral facial paralysis associated with involvement of both VI. In addition, there was microdactyly, syndactyly of the left hand, absence of the pectoralis major, of the mammary gland and nipple adding up to Poland syndrome. Surgery was envisaged with the aim of performing a hypoglossofacial anastomosis. Operation revealed muscles of normal appearance with a somewhat thin digastric and total absence of the facial nerve both at the point of its emergence through the stylomastoid foramen as well as in the parotid.
