Abstract: Objective To assess the short-term effect of resorbale implants in the treatment of orbital floor fractures. Design Retrospective case series. Participants 12 cases of orbital floor fractures with less than 2.6 cm2 of floor defect. Methods All the patients underwent orbital floor reconstruction via subciliary approach. The resorbale implants were placed on the surface of orbital floor defect. The orbital axial CT and coronal CT scans have been used and compared in all the cases preoperatively and postoperatively. The mean follow-up was 6.4±1.8 months. Main Outcome Measures Ocular symptom, radiological evaluation and complications. Results The diplopia and the restricted globe movement were resolved in 5/12 cases, improved in 7/12 cases. The infection and the extrusion of the implants did not occur after surgery. The paresthesia of the infraorbital distribution with different extent were observed in all cases and could be resolved within 3 to 6 months after operation. CT scans show that the orbital floor was reconstructed and the orbital implants did not dislocate. Conclusion The resorbable implant is an acceptable material for orbital floor reconstruction less than 2.6 cm2 in the short term. (Ophthalmol CHN, 2014, 23: 247-250)
