Computed tomographic scanning for locating an emplaced plastic orbital plate.

An emplaced plastic plate was demonstrated by computed tomographic scanning five years after surgical implantation because of fracture of the orbital floor, proving that it had remained in proper position and that the patient's complaints were unrelated to its presence in the orbit. To the best of our knowledge, this is the first instance in which this method had been used intentionally to achieve noninvasive localization of an orbital plastic plate. It is a valuable and accurate adjunct in ascertaining possible migration or early extension of the emplaced implant.
