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