Chowdhury and Krause propose that autologous grafts are preferable to alloplastic materials. It is easy for me to support their conclusions since they agree with my own. In almost 20 years of personal experience, I have seen several extrusions of Silastic orbital implants (like the one shown by Chowdhury and Krause) resulting in difficult-to-repair deformities of the involved lower lids, while I have encountered no extrusions of autologous bone grafts. However, bone grafts can undergo resorption, resulting in delayed changes in globe position that may require later revision surgery (if so desired by the patient).
