Abstract

Orbital fractures occur in a significant proportion of people who encounter blunt head trauma. A blowout fracture is that type which involves the orbital walls excluding the orbital rim.
The purpose of our study was to evaluate the use of the resorbable polylactic acid polymer implants (Resorb X) in management of orbital floor blow-out fractures as regards safety, cosmetic and functional results.
In a prospective, interventional case series, 22 patients with traumatic blow-out floor fractures underwent lower fornix transconjunctival repair using polylactic acid implant insertion over the defect without fixation. Orbital imaging was done preoperatively, at one month and one year postoperatively in the form of orbital CT with 2-mm cuts of axial, sagittal and coronal scans. Outcome measures included the maximum vertical height of the orbit at the fracture plane and its changes over time.
At final follow-up, both limitation of elevation and diplopia improved in 82% of cases, while 63.6% of cases showed improvement of enophthalmos. Radiological restoration of the orbital vertical height was recorded in 100% of cases without implant displacement at 1 month. However, after 1 year a significant floor bowing was found in 45.5% of cases which showed a strong positive correlation with preoperative defect size (r=0.820).
The study concluded that Resorb X mesh plates can be a good option for safe reconstruction of orbital floor blow-out fractures. Good anatomical and functional results were obtained in small-sized orbital floor defects. Late sagging under pressure may limit their use in medium-sized floor defects.
