Late reaction to silicone following reconstruction of an orbital floor fracture.

This report presented the clinical and radiographic findings, the surgical management, and the histologic features of a chronic inflammatory lesion that developed in response to a Silastic orbital floor implant placed 13 years previously. A review of the literature supported the fact that implanted solid film polymers can precipitate a continuous, chronic inflammatory response that is dynamic and that may be exacerbated by numerous factors.
