Teflon prosthesis in orbital floor fracture
Primary bone grafting is the recommended treatment for orbital floor fractures with bone defects, but this technique has a greater operative morbidity than the simpler use of the Teflon prosthesis. This study evaluates the use of the Teflon prosthesis. In 9 years, 110 patients with 115 orbital floor fractures were treated with Teflon prostheses. Of those, 90 patients had only orbital floor or orbito-zygomatic fractures and 20 had panfacial fractures. The mean operative time was 87 mins. Seventy-seven patients had good results. Complications included diplopia, ectropion, enophthalmia and palpable prosthesis. Seven prostheses required removal between three and 11 months postoperatively. No prosthesis became infected. Orbital floor reconstruction with a Teflon prosthesis is a relatively simple and short procedure associated with a low morbidity, giving good results except in cases of severe floor defects.
