Absorbable gelatin film verses silicone rubber sheeting in orbital fracture treatment.

Orbital floor fractures can result in herniation of orbital tissues and impairment of ocular function. In this experimental study, orbital defects were created surgically in cats. The gross and histologic healing of these defects was compared among animals implanted with silicone rubber sheeting or absorbable gelatin film and animals that received no implants. Both implanted animal groups demonstrated enhancement of healing. The absorbable gelatin film showed less migration, less inflammatory response, and improved healing. This animal study supports the use of absorbable gelatin film in the surgical management of orbital fractures.
