Fractures of the orbital floor. Apropos of a homogeneous series of 70 patients]

The authors report their experience based on a homogeneous series of 70 fractures of the orbital floor. Different anatomo-clinical forms were defined in particular fractures of the orbital floor, accompanying an "internal pivoting" of the cheek bone, which by their incarceration mechanism resemble the trap-door fractures. The blow-out fracture associated with the lower orbital margin also raises therapeutic problems. After a clinical and CT study, the authors recommend treatment via the lower orbital approach using silastic implants. The different sequelae are described clinically and are appraised medically and legally.
