Abstract:
PURPOSE: To report the results of surgical repairing of inferomedial orbital wall fractures accompanied with loss of bony strut by an overlapping method using Resorb X(R) plates (poly(D,L)-lactic acid). METHODS: To repair inferomedial orbital wall fractures with loss of bony strut, we bent the medial aspect of the plate for floor fracture according to the anatomical structure and then inserted the floor implant, which was supported by anterior, posterior and lateral margins of the floor fracture. Then, the medial implant, which was supported by the bent medial edge of the floor implant, was inserted. Postoperatively, we analyzed the outcomes of 21 patients regarding postoperative enophthalmos, limitation of eye movement (LOM) and diplopia. The diagonal lengths of the orbit in the operated side were compared with the non-traumatized side based on the coronal view of the postoperative CT scans to determine the success or failure of the reconstruction. RESULTS: The average postoperative enophthalmic value was 0.5 mm, and no significant differences between the orbital diagonal lengths of the operated and non-operated eyes were observed. The LOM shown in 7 out of 8 patients was completely resolved during the postoperative follow-up period. All patients with diplopia, including one patient who showed partial remission of LOM, experienced complete symptom resolution. No other complications related to the implant were recorded. CONCLUSIONS: Inferomedial orbital wall fractures with the loss of bony strut can be successfully repaired by the overlapping method using Resorb X(R) implants.
