[The orbitonasolabial flap. Anatomical and clinical study].

How to use the orbitonasolabial flap in vascular island thanks to his pedicle based an angular vessel. An anatomic study based on 11 cadavers allows to check the existence of a constant pedicle. This flap was used on 6 patients aged 62 to 90 years old on an average period of 16 months to fill up jugular, orbital, nasolabial and inner canthal defects. Two complications have occurred, a superficial necrosis of the lower part of the flap having spontaneously healed and an ectropion on a senile part. It has been necessary to degrease a second time in 50% of the cases. Nevertheless, the flap can be considered reliable and able to cover tissue defect in the central facial region with minor aesthetic and functional sequel on the donor site.
