Late extrusion of alloplastic orbital floor implants. 1993

Department of Maxillofacial Surgery, Queen Victoria Hospital, East Grinstead, Sussex.

Complications following the use of alloplastic orbital floor implants are well documented but it is not widely recognised that these can occur many years after initial treatment. Three patients who presented with late extrusion of an implant through the facial skin are reported. This complication occurred 10, 16 and 17 years respectively after treatment of the orbital floor fracture. The tissue reaction to silicone rubber and Teflon inplants is reviewed and the possible cause for this late complication is discussed.
