Abstract

The fractures of the orbital floor are common after craniofacial trauma. Repair with resorbable plates is a viable reconstructive option; however, there are few reports in the literature. This study describes our experience using copolymer polylactic and polyglycolic acid (PLLA/PGA) orbital reconstruction plates (LactoSorb, Lorenz Surgical, Jacksonville, FL) in 29 cases of the orbital floor fracture repair. We conducted a retrospective review of 29 orbital floor fractures at a single institution repaired through transconjunctival, preseptal dissection using PLLA/PGA plates fashioned to repair the orbital floor defect. Associated fractures included zygomaticomaxillary, LeFort, and nasoethmoid fractures. There were six patients with complications. Four patients had transient diplopia with complete resolution of symptoms within 1 year. One patient had diplopia postoperatively, but was later lost to follow-up. Two patients have had persistent enophthalmos since 1 year. In each of these cases, the floor fracture was coincident with significant panfacial or neurotrauma. We did not encounter any adverse inflammatory reactions to the implant material itself. The study concluded that orbital floor fracture repair with resorbable plates is safe, relatively easy to perform, and in the majority of cases was effective without complications. In the presence of severe orbital trauma, more rigid implant materials may be appropriate.
