Enophthalmos of 2 mm or more is aesthetically unacceptable and usually requires surgical intervention. For complex orbitofacial fractures with ocular retrusion, combined modalities such as reduction of the herniated content, osteotomy, fixation of fracture, and placement of onlay graft to support the orbital structures and to correct enophthalmos are usually necessary.1 However, in cases in which loss of volume is not associated with fracture, volume augmentation alone can be performed through placement of autogenous tissues and alloplastic materials such as blocks, sheets, beads, and injectable forms.2-8
