Experimental repair of orbital floor fractures

Eight rhesus monkeys (16 orbits) were used to evaluate the treatment of experimentally created orbital floor fractures. The fractures were repaired with antral bone, Silastic, and gelatin film implants and studied clinically and histologically. Four orbits were used as controls. All implants appeared to favorably influence healing by preventing entrapment of the orbital contents within the reparative tissue. Autogenous bone appeared to be the best implant. Silastic and gelatin film were also effective and well tolerated.
