Orbital Floor Reconstruction With Ethyl-2-Cyanoacrylate

Abstract

The orbital floor is one of the most frequently broken bones in maxillofacial fracture, and orbital reconstruction is needed in many cases. Various materials are used for orbital floor reconstruction. We report here orbital reconstruction using autologous orbital bone with cyanoacrylate. Entrapped soft tissues were freed and repositioned intraorbitally and bone fragments were gathered with a microscope simultaneously. The bone fragments were fixed to a board of bone with ethyl-2-cyanoacrylate and returned to the orbital fracture site. Of 96 fresh orbital floor fractures, this method was used for 31 (32.3%) patients. Simple reduction was performed in 48 patients. Bone graft with iliac crest was performed in the other 12 patients. Reconstruction with alloplastic materials was performed in 5 patients. Diplopia was corrected in 26 patients on whom this method was performed. The reconstructed bone collapsed into the maxillary sinus in 1 patient who underwent iliac bone graft on reoperation. Another 4 patients did not show diplopia preoperatively. None of the patients showed enophthalmos, foreign body reaction, or infection postoperatively. We were able to perform orbital bone reconstruction with autologous orbital bone without another donor site in 30 (62.5%) of 48 cases that required grafting. The indications for this method are that a sufficient quantity of bone fragments can be obtained and returned on a board of bone which can be stabilized in the orbit without collapsing into the maxillary sinus. Good results were obtained, and we consider this to be a safe and useful method.
