title: A use of poly-L-lactide, D-lactide sheet on posterior orbital floor fracture.
abstract: We present the cases of orbital posterior wall fractures that were fixed with poly-l-lactide, D-lactide (PLDLA) sheets. Poly-L-lactide, D-lactide sheet (0.5-mm thickness) was shaped exactly to fit to the area of orbital floor, and then an extended 1 cm was bent across on the infraorbital rim. That part was fixed with 2 absorbable screws to prevent the sheet from crumpling. Orbital floor fractures of 6 patients (3 posterior-one-half defects and 3 posterior-two-thirds defects) were repaired using PLDLA sheets. Diplopia in 5 patients before surgery was improved, usually within 6 months postoperatively. Clinical enophthalmos was not appreciated in any patient. However, preoperative exophthalmometry measured -1.3 +/- 0.3 mm and postoperatively -0.4 +/- 0.2 mm, respectively. Poly-l-lactide, d-lactide sheet is applicable to safely repair the orbital posterior floor fracture.
