Secondary correction of traumatogenic enophthalmos with auto- and alloplastic implants

In 23 patients with traumatogenic enophthalmos and diplopia autologous (rib cartilage, iliac crest bone), heterologous (lyophilized dura), and alloplastic (Silastic, P.D.S., HA-blocks) material was implanted into the orbit in a late secondary intervention. The results were encouraging as for the improvement of the diplopia as well as the enophthalmos. If rib cartilage should not or cannot be used a hydroxyapatite ceramic block is the best alloplastic implant material due to its stability, inertia, and availability.
