Alloplastic template fixation of blow-out fracture.

Alloplasts are widely used to reconstruct the orbital defects. The alloplastic material, however, is not uncommonly infected, displaced, and extruded, and forms an epithelial pseudocyst around it. To prevent the depressed fractured bone of the orbital floor from dropping down into the maxillary sinus, an en block fragment of the depressed fracture of the orbital floor was restored after being attached to an alloplastic sheet template which was fixed to the intact orbital floor. This procedure is simple and secure, and intramaxillary packing is not needed to buttress the depressed fractured bone into the sinus.
