Abstract
Purpose:
To evaluate the surgical outcomes of simple orbital fractures with porous polyethylene implant at early and late surgical repair.
Methods:
Long-term, observational and retrospective study of 40 patients with simple orbital fracture, without previous treatment, underwent porous polyethylene implant. It was done since 2006 to 2012. Early and late surgical management of orbital fracture with a porous polyethylene implant was done, focusing on implant survival time without complications. A descriptive and comparative statistical analysis with T-student, Anova and Kaplan survive curves was done.
Results:
34 males and 6 females were enrolled in the study with a mean age of 31 years. The most frequent diagnosis was orbital floor fracture and symptom was diplopia (55%). A mean follow-up of 14.5 months, 27.5% underwent early surgery and 72.5% late (>2 months) repair. Early surgical management improves diplopia in 55.5% and reduces enophthalmos of 2mm to 0.857 mm. The late surgical management improves diplopia in 75% of patients and reduces enophthalmos of 3.02 to 1.862mm. The implant survival time without complications was greater in patients underwent early surgical management and only 25% of complications were present after 2 months of surgical intervention.
Conclusions:
The early surgical management of orbital fractures with porous polyethylene implants has better enophthalmos correction and without survival implants complications. Whereas that, late surgical management reduces diplopia with low implant complications in this study. The porous polyethylene implant is a safe material to repair orbital fractures, so it is important to identify principal symptom and special attention at the time of presentation, to offer better surgical outcomes.
