[Reflections concerning reconstruction of the floor of the orbit using a metal grill (author's transl)].

The author presents four cases of patients with collapse of the floor of the orbit, total in three cases and partial in one. The material used was cut from the perforated plates used classically in maxillo-facial surgery. In one cases, the approach was mixed--sinusal and sub-orbital--whilst in the other three a classical sub-orbital-palpebral approach was used. There was one complication of infection 15 days after insertion in the case in which a mixed approach was used, this having no sequelae--one and a half year having elapsed. In all cases, the Lancaster test returned to normal, proving the perfect mobility of the eyeball over the plate. Despite the small number of cases, and a follow-up of no more than one and a half years, the author feels that the ease of use of these plates and the good results obtained here offer a possible future for this method.
