[Long-term complications of silicone implants used in the repair of fractures of the orbital floor].

A 15 patients series is presented concerning complications following the use of silicone orbital floor implants. The more frequent complications are inferior eyelid swelling, pain and ocular dystopia. Complications may occur very belatedly, 10 years for a patient, 9 years for an other. The mean delay from insertion to removal for complication of the implant is 4.3 years. Sinus troubles are found in 70% patients that may indicate a relationship between sinusal pathology and complications observed. The CT study is described. Precautions in insertion of the implant are given. Suggestions are done to prevent such complications.
