Abstract
Proplast was implanted in 15 cases of orbital reconstruction. Seven cases were orbital floor fractures, four cases were phthisical enophthalmos, and four cases were anophthalmic enophthalmos. In orbital floor fracture cases, thin (2-mm) Proplast was placed onto the fractured orbital floor after the incarcerated orbital tissue was released. To correct the enophthalmic socket, Proplast was shaped into small pieces (10 x 5 x 2 mm), then inserted into the subperiosteal space from all directions to fill up the orbital cavity. The results of these 15 cases were satisfactory. The average follow-up period is 13 months. The increased orbital volume seems less than the volume of the implanted Proplast; therefore, we suggest an 80-90% overcorrection rate in accordance with the computer measurements. In sum, Proplast serves as a very good material for orbital floor reconstruction and volume replacement.
