A Silastic sheet was used for the repair of a lateral orbital wall defect in a 48-year-old man. Migration of this implant through the defect has caused recurrent episodes of orbital infection. Although migration of Silastic within the orbit has been reported previously, the absence of fixation together with further remodelling of the lateral orbital wall defect contributed to this phenomenon.
